# How Long Does It Take to Build an App? Real Timelines, Phase by Phase DreamLabs is an AI-powered app development agency in California — a fractional product team for mobile and web apps, from strategy to launch. Get version one into users' hands this quarter, on a launch date you can plan around. For founders and teams with a date to hit, DreamLabs designs and builds the app: a two-week strategy sprint scopes your first release, and most builds take about 6 weeks after it. Store review usually adds days, not weeks. Here's every phase, with timelines from our published case studies. By John Krueger and Tomás Quiñonez-Riegos. Updated October 8, 2026. ## From idea to the app stores, phase by phase | Phase | How long | What sets the pace | | --- | --- | --- | | Strategy sprint (DreamLabs) | Two weeks, for a flat $4,000, refunded in full if we don't move forward together | How quickly you decide what version one must prove. It ends with a features table, wireframes, first-release scope and a build price you approve | | Design and build | About 6 weeks for most DreamLabs builds. Published examples: three weeks of development for OOM, eight weeks from idea to launch for GlowCode | Features and user types, integrations, and how fast feedback comes back | | Developer accounts | Start in week one; both stores verify who you are | Apple also verifies an organization's legal entity status and address | | App Store review | At least 50% of submissions reviewed in under 24 hours, 90% in under 48 (Apple) | A complete submission, including a working demo account for anything behind a sign-in | | Google Play review | Up to seven days, or longer in exceptional cases, for some accounts. New personal accounts first run a 14-day closed test, then a production-access review that usually takes seven days or less | Account type and age, and your testing history | | Launch and iterate | Ongoing: Grove shipped 12 updates between its February 3, 2026 App Store launch and August 13 | What users tell you, turned into a monthly roadmap | | For comparison: a typical app project | About 11 months (Clutch, from verified client reviews) | Scope: the number of features and user types | DreamLabs timelines as published on each case study. Store review times and rules from Apple and Google, and Clutch's market timeline, checked October 8, 2026; sources in the guide below. ## Frequently asked questions ### How long does it take to build an app? A focused first release can take weeks; a large product can take a year. Clutch's 2026 data puts the typical mobile app project at about 11 months. At DreamLabs, a two-week strategy sprint scopes version one and most builds take about 6 weeks after it. Grove, our own product, went from idea to both app stores in six weeks. ### How long does it take to build an MVP? At DreamLabs, about eight weeks for most projects: a two-week strategy sprint, then about 6 weeks of design and build. Published examples include three weeks of development for OOM and eight weeks from idea to launch for GlowCode. Store review usually adds days, and a new personal Google Play account adds a 14-day closed test. ### How long does App Store review take? Apple says App Review typically reviews at least 50% of submissions in less than 24 hours and 90% in less than 48 hours. Incomplete submissions may be delayed or may not pass, so include review notes and a working demo account for anything behind a sign-in. You can request an expedited review for a critical bug fix or an app tied to an upcoming event. ### How long does Google Play review take? Google says some developer accounts get extended reviews of up to seven days, or longer in exceptional cases. Personal developer accounts created after November 13, 2023 must first run a closed test for at least 14 days, then apply for production access, a review Google says usually takes seven days or less. ### Why do agencies quote six months or more? Often because of scope. Clutch's 2026 data puts the typical mobile app project at about 11 months, and agencies had quoted Urban Outdoors six months for its MVP before we delivered a no-code version in four weeks. A long timeline often means a long feature list. Cutting version one to what it must prove is the biggest schedule change available to you. ### Does AI make app development faster? It does for us. We build with AI-accelerated development, and Grove, our own product, was built with Claude Code as part of that workflow and went from idea to both app stores in six weeks. AI speeds up writing and testing code. It doesn't speed up deciding what to build, store review or learning from users, so planning still sets the schedule. ### What slows an app project down the most? Scope that grows mid-build and decisions that wait. Store accounts left to launch week come next, because both stores verify your identity and new personal Google Play accounts need a 14-day closed test. A written first-release scope and one decision-maker on your side protect a launch date better than anything else. ### How long does DreamLabs take, and what does it cost? Every project starts with a two-week strategy sprint for a flat $4,000, refunded in full if we don't move forward together. The build price is set and approved at the end of the sprint, and that's what you pay. Most builds take about 6 weeks after the sprint. ## Launch in weeks, on a date you can plan around This guide is for founders and teams who need a launch date they can plan around: a board meeting, a pilot customer, a funding milestone. For a focused first release, plan in weeks, not months. At DreamLabs, a two-week strategy sprint scopes version one, most builds take about 6 weeks after it, and Apple reviews most submissions within a day or two. The longer numbers you'll see elsewhere are real too: [Clutch's 2026 data](https://clutch.co/directory/mobile-application-developers/pricing) puts the typical mobile app project at about 11 months, and hiring your own team first adds recruiting time, a median 75 days to first fill a technical role according to [Ashby's 2026 hiring data](https://www.ashbyhq.com/talent-trends-report/reports/recruiting-operations-benchmarks-talent-trends). The difference is mostly scope: what version one has to prove, and what it can leave for version two. Every outside figure below links to its source and was checked on October 8, 2026. We learned this as clients first. In 2020, when Tomás and John needed a web app, a team of traditional developers told them the prototype would be ready within one month. Several months later it still wasn't complete, and it was well over budget. They built it themselves in two weeks instead, and DreamLabs started there ([our story](https://www.dreamlabs.pro/about)). ### Timelines from apps we've shipped These are the timelines as published on each case study. Development figures start once user stories and wireframes were done; end-to-end figures include planning. - [Grove](https://www.dreamlabs.pro/project/grove), our own climate fintech app: idea to both app stores in six weeks, with card linking, ACH payments and SMS sign-in. - [Nurture](https://www.dreamlabs.pro/project/nurture): 36 features in four weeks of development, six weeks in all, for a bilingual learner app and its admin tools. - [KPI Dash](https://www.dreamlabs.pro/project/kpi-dash): an AI-powered web app with 15 features in four weeks of development. - [OOM](https://www.dreamlabs.pro/project/oom): three user types working from one QR-code record, three weeks of development and seven weeks end to end, then launched on both app stores. - [GlowCode](https://www.dreamlabs.pro/project/glowcode): idea to launch in eight weeks, in three phases, on both app stores. - [Haikuists](https://www.dreamlabs.pro/project/haikuists): a native mobile app for contract poets and a desktop web app for admins, the first version of both in eight weeks. - [Community Gearbox](https://www.dreamlabs.pro/project/community-gearbox): six weeks end to end, from strategy to launch. - [Urban Outdoors](https://www.dreamlabs.pro/project/urban-outdoors): a no-code MVP built in Adalo, four weeks end to end (a week of roadmap, six days of building, two weeks of QA), after agencies had quoted six months. ### Phase 1: the strategy sprint (two weeks) Most schedule slips start as scope questions nobody answered before the build. The sprint answers them first: what version one must prove, a full features table, UX wireframes for your core flows and the scope of your first release. The build price is set and approved at the end of it, so the build starts from a plan and a number rather than an estimate. If you'd like a head start, our free [product roadmap template and guide](https://www.dreamlabs.pro/blog/product-management-fundamentals-for-your-mobile-app) walks through the same thinking. ### Phase 2: design and build (about six weeks) We build with AI-accelerated development: mostly in Flutter, in Swift when native iOS is the right call, and in React, React Native and Next.js on Firebase or Supabase. One Flutter codebase ships to both app stores, as GlowCode's did, so iPhone and Android don't need two separate schedules. We test on real devices. Whether this phase takes four weeks or eight comes down to the number of features and user types, integrations such as payments or bank linking, and how quickly decisions come back. ### Phase 3: store review (usually days) Apple says App Review typically reviews [at least 50% of submissions in less than 24 hours and 90% in less than 48 hours](https://developer.apple.com/distribute/app-review/), and that incomplete submissions may be delayed; if features require a sign-in, Apple asks for a working demo account. On Google Play, [some developer accounts get extended reviews](https://support.google.com/googleplay/android-developer/answer/9859751) of up to seven days, or longer in exceptional cases. One rule adds weeks if you don't plan for it: [personal Google Play developer accounts created after November 13, 2023](https://support.google.com/googleplay/android-developer/answer/14151465) must run a closed test for at least 14 days before they can apply for production access, and Google says that review usually takes seven days or less. Open your developer accounts in your company's name in the first week. Apple verifies an organization's [identity, legal entity status and address](https://developer.apple.com/programs/enroll/) during enrollment, and Google Play asks every new developer to [verify their identity](https://support.google.com/googleplay/android-developer/answer/6112435). ### Phase 4: launch, then keep shipping A first release starts the learning, so plan the second one before the first ships. Grove shipped 12 updates between its App Store launch on February 3, 2026 and August 13, including a full design overhaul and Google and Apple sign-in. Nurture reached 19 releases across its mobile app and admin web app by August 2024, and the app still receives updates. After GlowCode launched, we led four user testing sessions that produced 24 points of feedback for product improvement; our [user testing guide](https://www.dreamlabs.pro/blog/user-testing-guide-for-apps) shows how to run them. [UNALTERED](https://www.dreamlabs.pro/project/unaltered) grew over three releases in 13 months. ### What stretches a timeline - **Scope that grows mid-build.** Every added feature lands on a schedule that was set without it. Keep a version-two list and park new ideas there. - **Decisions that wait.** A build stalls whenever a question does. Name one person who can approve screens, copy and trade-offs within a day. - **Accounts left to launch week.** Store enrollment, identity checks and Google's closed-test rule all run on their own clocks. - **Providers with their own onboarding.** Payments, bank data and messaging services have setup steps of their own; Twilio, for example, notes that US business texting on standard 10-digit numbers is subject to [A2P 10DLC registration](https://www.twilio.com/en-us/sms/pricing/us). Start those in week one. - **Content and data that aren't ready.** Lessons, product catalogs and imported records are often the last thing to arrive. Treat them as part of the scope, with dates. ## When a fast build isn't the right plan A short build is the right goal for most first releases. Here's when a different plan will serve you better. - **You need something to show this week.** An AI app builder or a clickable prototype gets you a demo in days. Bring it to us when it has to hold real users and real data; our [AI prototype to production guide](https://www.dreamlabs.pro/services/ai-prototype-to-production) covers that step. - **The date is fixed and the scope can't shrink.** No team can honestly promise both, and you should hear that before you sign. The strategy sprint is where that conflict surfaces, before you've paid for a build. - **Your launch waits on someone else's approval.** If a regulator, a partner or a customer's security review sets the date, build speed won't move it. Plan around that approval first. - **You need many teams working in parallel.** We're a small senior team. Large multi-team programs fit a larger agency. - **Your own engineers already know the codebase.** On a short timeline, an outside team's ramp-up can cost more time than it saves. - **Your product needs a stack we don't build in.** We build most apps in Flutter, work in Swift when native iOS is the right call, and build React, React Native and Next.js apps on Firebase or Supabase. If yours needs something else, hire specialists in it. ## Two weeks to a plan, about six to launch DreamLabs is an AI-powered app development agency in California that works as a fractional product team, from strategy to launch. Tomás Quiñonez-Riegos leads product and John Krueger leads development ([meet the founders](https://www.dreamlabs.pro/about)). - **Two weeks to a plan.** Every project starts with a strategy sprint for a flat $4,000: product strategy, a full features table, UX wireframes for your core flows and the scope of your first release. It's refunded in full if we don't move forward together. - **About six weeks to launch.** The build price is set and approved at the end of the sprint, and that's what you pay. With AI-accelerated development, most builds take about 6 weeks, with end-to-end QA on real devices and app store publishing included. - **Proof on the stores.** [Grove](https://www.dreamlabs.pro/project/grove) reached both app stores six weeks from idea. [Nurture](https://www.dreamlabs.pro/project/nurture) shipped 36 features in four weeks of development and has been on the App Store since March 2023. - **Yours from day one.** You own every line of code, every signing credential and every store account. - **Then keep shipping.** Stay with us monthly, priced from your roadmap, or hand the product to your own team. Erick Szentmiklosy, co-founder of [Haikuists](https://www.dreamlabs.pro/project/haikuists): “They delivered on time every single time.” ## Five ways to protect your launch date ### Write down what version one must prove One outcome: paying users, a pilot customer, a metric for your next round. Everything that doesn't serve it goes on the version-two list. This is the biggest single lever on your timeline. ### Open store accounts in week one Enroll in the Apple Developer Program and Google Play Console in your company's name at the start. Both verify who you are, and new personal Google Play accounts must run a 14-day closed test before they can apply for production access. ### Decide within a day Name one person who can approve screens, copy and trade-offs. A six-week build has no room for week-long feedback loops. ### Submit complete Give App Review everything it needs, including review notes and a working demo account for any feature behind a sign-in. Apple says incomplete submissions may be delayed or may not pass. ### Plan release two before release one ships Decide how you'll learn from your first users, through analytics, user testing or both, so the weeks after launch produce decisions as well as downloads. ## Case studies - [Grove](https://www.dreamlabs.pro/project/grove.md): Climate fintech round-up app - [Nurture](https://www.dreamlabs.pro/project/nurture.md): Native Mobile App - [KPI Dash](https://www.dreamlabs.pro/project/kpi-dash.md): AI-powered web app ## Links - Full page: https://www.dreamlabs.pro/services/how-long-to-build-an-app - Offerings & pricing: https://www.dreamlabs.pro/offerings - Contact: https://www.dreamlabs.pro/contact
