Fitness App Development Company

Fitness app development company for apps people keep opening.

The Real Challenge

Downloads are easy. Day 30 is hard.

Most fitness and wellness apps lose the majority of their users within the first few weeks. The ones that last aren’t the ones with the most features; they’re the ones that help people feel progress early and come back tomorrow.

Our approach: design the first week around small wins, then measure day 1, 7 and 30 retention from launch.

01
Generic plans on day one
Users who don’t see themselves in the first workout don’t open the app again.
02
Progress nobody can see
Without visible wins, motivation fades before results arrive.
03
Reminders that nag
Too many or badly timed notifications get the app muted, then deleted.
04
Paywall too early or too late
Subscriptions convert when users have felt the value, not before.

Case Study

QalbSync: a habit app built for daily use.

QalbSync’s founder needed a habit-tracking app that showed progress across weekly, monthly and yearly views. We designed the visual identity and icon system, built the app in Flutter from one codebase, and handled app store optimization and mobile app marketing for launch.

Core Tracking Modules

QalbSync needed one app, not two separate builds, that could track multiple habit types, visualize progress across weekly, monthly, and yearly views, and handle a complete account lifecycle from onboarding to account deletion. We built it in Flutter, designed the full visual identity, and handled discoverability through mobile app marketing and ASO.

Fitness app development questions

About our fitness and wellness app development services. Ask us anything else.

A fitness app blueprint starts from $4,000. A fitness or wellness app MVP for iOS and Android starts from $18,000, and platforms with coaching, video libraries, wearables or gym management features from $35,000. App store fees and subscription tools are billed to your own accounts.

Most fitness and wellness MVPs launch in 10 to 16 weeks, including design, development, testing and app store submission.

Start with personalised onboarding, a clear daily plan or workout, progress tracking, streaks and reminders, and Apple Health or Health Connect sync. Add coaching, community, challenges and video content once people are using the core experience.

Most use subscriptions with a free trial, sometimes alongside one-off programmes, coaching packages or gym memberships. In-app purchases through Apple and Google carry store fees, so we plan pricing and paywalls with those in mind.

Yes. We integrate HealthKit on iPhone and Health Connect on Android, and can build Apple Watch or Wear OS companions or connect to wearable platforms where they offer APIs.

By making the first week succeed: a personal plan on day one, small wins, streaks, well-timed reminders, visible progress and community. We track day 1, day 7 and day 30 retention from launch and improve the weakest step first.

Most consumer fitness and wellness apps are not covered by HIPAA, but they still handle sensitive data and must follow privacy laws and app store health data rules. If your app works with healthcare providers, our healthcare software development team designs for HIPAA from the start.

Yes. We build branded apps for class booking, memberships, check-in, trainer schedules and member communication, and can connect to existing studio management software where it offers an API.
