FitnessSyncer

i 3 Table Of Content

FitnessSyncer is the “universal translator” of the health and fitness world. For businesses that want to support everything—from specialized power meters and smart scales to niche rowing apps—FitnessSyncer is the solution. It acts as a massive data aggregator that supports over 50 different health and fitness clouds, unifying them into a single, consistent stream of data.

Instead of building individual integrations for 50 different apps, you can integrate with FitnessSyncer. This gives your website instant compatibility with everything from Fitbit and Garmin to Withings, Polar, Suunto, and even specific medical devices like blood glucose monitors. It is the most cost-effective way to ensure that no client is ever “left out” because of the device they choose to use.

We use FitnessSyncer to help our clients build “agnostic” fitness platforms. We handle the integration with the FitnessSyncer API, allowing you to offer a “Connect Your Apps” feature that covers almost the entire market. This is particularly valuable for corporate wellness programs or large-scale fitness communities where you cannot control which hardware your members use.

Features

  • Massive Integration Library: Support for 50+ sources including Coros, Oura, Withings, Polar, and Hammerhead.

  • Unified Dashboard: One API call to retrieve data from multiple different sources for a single user.

  • Data Normalisation: Automatically converts different units and formats into one standard JSON output.

  • “ShoeRenew” Logic: Built-in tracking for equipment wear and tear (e.g., mileage on running shoes).

  • Historical Migration: Tools to help users move their data from one service to another.

  • Reporting Engine: Automated email progress reports and social postings based on aggregated data.

FAQs

Does the user need a FitnessSyncer account? Yes, the user typically creates a FitnessSyncer account to act as their “hub.” However, we can often white-label much of this experience so it feels like a part of your own website.

Is there a limit on how many devices I can connect? The standard version allows up to 5 sources/destinations. For businesses, we can implement Pro or Enterprise tiers that offer unlimited connectivity for your clients.

Can it track medical data? Yes, it supports many “wellness-medical” devices like smart scales, blood pressure monitors, and glucose meters. However, it is not intended for acute medical use.

How does it handle duplicates? FitnessSyncer has built-in logic to detect and remove duplicate activities (e.g., if a user records a run on both their watch and their phone simultaneously).

Can I export data to other apps? Yes, FitnessSyncer is bi-directional. It can take data from your website and “push” it to the user’s Fitbit or Strava account.
