# Build Your Own Fitbit Alternative - Tool: Build Your Own SaaS Alternative - Last updated: May 2026 ## TL;DR Fitbit, acquired by Google in 2021 for $2.1B, is being absorbed into Google Health. The Premium subscription jumped from $79.99 to $99.99/year in 2025, essential metrics are paywalled, and forced Google account migration upset longtime users. Building a custom fitness tracking app (no hardware) costs $700K–$1.6M over 9–14 months. OSS alternatives Gadgetbridge, OpenTracks, and Wger are available for self-hosting. ## Frequently asked questions ### How much does it cost to build a Fitbit alternative? A software-only fitness platform (importing from HealthKit/Health Connect, no custom hardware) costs $700K–$1.6M with an agency over 9–14 months. Adding custom BLE wearable hardware development adds $3M+ to the budget. Using OSS (Gadgetbridge + Wger self-hosted) cuts cost to $20K–$100K for a self-hosted solution. ### How long does it take to build a Fitbit clone? 9–14 months for a software-only platform with a 4–6 person team. Hardware wearable development adds 18–24 months to the timeline. A self-hosted OSS stack (Gadgetbridge + Wger) can be operational in 2–4 weeks for technically proficient users. ### Are there open-source Fitbit alternatives? Yes — Gadgetbridge (Android, AGPL-3.0, supports Fitbit wearables — hosted on Codeberg, star count unverified), OpenTracks (Android, Apache 2.0, GPS tracking), and Wger (Python/Django, AGPL-3.0, workout logging). None provides the full health dashboard experience. Gadgetbridge is the most relevant as it connects to actual Fitbit hardware. ### Can I build a fitness app without building a wearable device? Yes — Apple HealthKit (iOS) and Google Health Connect (Android) aggregate health data from all connected wearables and provide it via API to third-party apps. A custom fitness platform importing from these APIs gets Fitbit, Apple Watch, Garmin, and other wearable data without building any hardware. This is the recommended approach for app-only fitness platforms. ### What happens to my Fitbit data if Google discontinues the service? Google has not announced any plans to discontinue Fitbit or Google Health as of May 2026. However, Alphabet's history of product shutdowns (Google+, Stadia, Google One VPN) creates legitimate concern. Fitbit's privacy policy allows downloading your data to JSON via Google Takeout — download it now regardless of whether you plan to leave. ### Can RapidDev build a custom fitness tracking app? Yes — RapidDev has built 600+ apps including health data platforms, wearable integrations, and biometric dashboards. We scope fitness app builds from $100K for HealthKit/Health Connect importers to $1.5M for full health platforms with ML analytics.

Consumer fitness apps (steps, sleep, activity) are generally not covered under HIPAA because they are not used in the delivery of healthcare. However, if your app is used by healthcare providers as part of treatment decisions, or if you are a Business Associate to a covered entity, HIPAA applies. Build on HIPAA-eligible AWS services (or equivalent) and implement appropriate safeguards from the start — retroactive HIPAA compliance is significantly more expensive. --- Source: https://www.rapidevelopers.com/clone/fitbit © RapidDev — https://www.rapidevelopers.com/clone/fitbit
