Mobile app development that stays on the home screen

Stepler, the Swedish fitness app we built end to end: it launched as the #1 fitness app in Sweden in 2020, has passed 10M+ downloads and serves millions of users across 12 markets, on a React Native client that reads steps from Apple Health and Android Health Connect. Guidable, an audio-tour app with hundreds of thousands of users across Germany, backed by Deutsche Telekom. Faktastisch, a German online magazine live on iOS and Android at millions of pageviews a month. All three are in the stores today.

The Stepler case study Guidable

It depends on scope, and anyone quoting one number before a scoping call is guessing. For orientation, the 2026 market bands published by GoodFirms across 267 agencies run $15,000 to $40,000 for a simple MVP, $40,000 to $120,000 for a mid-complexity app with payments, push and an admin panel, and $100,000 and up for products with real-time features or compliance, with maintenance at 15 to 25 percent of the build per year. Our estimator gives you a range for your scope in about two minutes, and a scoping call turns that range into a fixed quote.

A focused MVP typically runs two to four months from kickoff to store listing; a mid-complexity app four to nine. Store review is its own line in the plan: Apple reports that 90 percent of submissions are reviewed within 24 hours, and Google Play requires a new personal developer account to run a closed test with 12 testers for 14 consecutive days before it can publish, so a first-time launch under a new account needs about three weeks for that alone. We schedule both from the start rather than discovering them at the end.

React Native for most products: one codebase, native components on each platform, Expo tooling, and the New Architecture as the default since React Native 0.82. Native Swift and Kotlin when the product is the platform: regulated data, heavy camera or AR work, or an Apple-first audience. Flutter is a credible alternative and our comparison guide weighs it honestly. If you already have a React or Angular web app, Capacitor (Ionic) can wrap it for the stores, and we will say so when that is the cheaper path rather than default to what we prefer to build with.

React Native vs Flutter Hire React Native developers Ionic and Capacitor

You do. The repository lives in your GitHub or GitLab organization with our engineers as collaborators, the Apple Developer and Google Play accounts are opened in your name, and so are Firebase, AWS and every third-party key. The contract is work-for-hire, source and design files are handed over at every release, and we sign an NDA before the first call if you want one.

Apple has required uploads built with the iOS 26 SDK since 28 April 2026, and it still rejects builds whose third-party SDKs ship without privacy manifests. Google Play has required new apps and updates to target Android 16 (API level 36) since 31 August 2026. Texas requires age assurance for new Apple accounts since June 2026, with Utah and Louisiana following, so apps with users in those states implement Apple’s Declared Age Range API and Google Play’s Age Signals. We track these as part of the build, not as a surprise at submission.

2muchcoffee is a US company headquartered in St. Petersburg, Florida, with a distributed senior team and US business-hours overlap. You can bring us in as a dedicated team inside your process and your board, hand us the whole build as a project with agreed outcomes, or mix the two. We have shipped software since 2015 and hold a 5.0 rating on Clutch across 26 reviews.

Our St. Petersburg office

Yes, and it starts with a code review rather than a rewrite pitch: we read the codebase, list what blocks the next release, and quote the takeover against that list. The usual first jobs are dependency and SDK upgrades, the React Native New Architecture migration, crash fixes, and the store compliance work described above. The team that does the review is the team that carries the app afterwards.
