Every question the Fitness APIs pages answer
The 17 fitness apis pages answer 84 named questions between them. Every one is listed below, and every link lands on the paragraph that answers it rather than the top of the page.
The Best Exercise Database APIs for Developers (2026)
- What is the best free exercise database API?It depends on whether you want an API or data you own. For a hosted API, AscendAPI's ExerciseDB V1 is free with no key: 1,500 exercises…
- Is ExerciseDB the same as AscendAPI?exercisedb.dev now presents itself as AscendAPI, previously ExerciseDB, and AscendAPI's documentation names the ExerciseDB/exercisedb-api…
- Which exercise API has GIFs or video demonstrations?AscendAPI's ExerciseDB V2 gives each exercise an MP4 demonstration video, through RapidAPI, with watermarked media on its free plan; its V1…
- Is wger's exercise API really free to use?Yes. wger is open source with no per-request fees, and its code marks the exercise endpoints as readable by everyone. The costs are…

The Best Wearable Fitness & Health-Data APIs (2026)
- Are wearable fitness APIs free to use?As of 2026, Fitbit/Google, Garmin, Oura, WHOOP and Polar all publish no per-call fee and are documented as free to use. The real cost is…
- Which wearable API is best for GPS and running data?Garmin is generally the richest for GPS, multisport and endurance metrics, with an Activity API for per-activity data such as running,…
- Do wearable APIs push data to me, or do I have to poll for it?It varies by provider, and it changes your architecture. Garmin delivers through registerable push and ping callback URLs, so you build an…
- Do wearable APIs let me pull data for all users at once?No. These are consent-based OAuth 2.0 APIs that return data only for individual users who explicitly authorize your app — none is a bulk or…
- Which wearable API has the least approval friction?Polar's Open AccessLink is generally the most self-serve: you register a client yourself and tokens are long-lived. The trade-off is that…
The Best Health-Data Aggregator APIs (2026)
- What is a health data aggregator API?It is a server-side API that normalizes data from many wearables and health accounts behind one integration, so you connect once instead of…
- How is an aggregator different from Apple HealthKit or Google Health Connect?HealthKit and Health Connect are on-device stores, one per platform, and only expose what is on that phone. Aggregators work server-side…

- Is there a free AI workout tracking API?The pose-estimation primitives are free: MediaPipe/BlazePose and TensorFlow MoveNet are Apache-2.0, and Apple Vision and ML Kit come with…
- Can I build my own rep counting instead of using an SDK?Yes. Free pose primitives give you the keypoints, and you can write your own rep-counting and form logic on top. The trade-off is that this…
- Which AI motion-tracking SDK is best for physiotherapy or rehab?Kemtai is positioned for clinical, physiotherapy, and MSK use cases: its site describes embeddable exercise and patient-management…
- Do these workout tracking SDKs run on-device or in the cloud?The raw pose primitives run on the client. The commercial SDKs all claim on-device analysis, with differences worth checking: QuickPose…
The Best Nutrition & Food Database APIs (2026)
- What is the best free nutrition API?The USDA FoodData Central API is the best free source for authoritative nutrient data — it is public domain (CC0) and needs only a free…

- Which free fitness APIs let you self-host the data?For obligation-free bootstrapping, the free-exercise-db dataset (876 exercises when we counted it on October 22, 2026, public domain,…
- Are Apple HealthKit and Google Health Connect free?Yes, both are free to use with no per-call fee. The catch is that they are platform-bound: HealthKit runs only on Apple devices and Health…
- Is USDA FoodData Central free for commercial use?Yes. USDA FoodData Central is U.S. government data published in the public domain under CC0, so it is free for any use including…
- What is the catch with free-tier fitness APIs?Free tiers of commercial APIs are access you borrow, not data you own. Expect hard rate limits, no support or SLA, and feature or media…
Apple HealthKit vs Google Health Connect (2026)
- Is HealthKit or Health Connect better for a cross-platform app?Neither on its own. They cover different operating systems, so a cross-platform app implements both — HealthKit on Apple platforms and…
- What review or declaration steps do HealthKit and Health Connect require before launch?Both gate your release on a declaration, not just on code. On Apple platforms you add the HealthKit capability and the purpose strings that…
- Can a HealthKit app tell if the user denied read access?No. By design, denied read permission in HealthKit returns empty data rather than an error, so the app cannot distinguish a denial from a…
- How much history can Health Connect read by default?Data from up to 30 days before the app's first permission grant, unless it holds PERMISSION_READ_HEALTH_DATA_HISTORY. Without it, Google's…
- Are HealthKit and Health Connect free?Neither setup involves an API key or a billing account. HealthKit is a capability you switch on in Xcode, and Apple's capability table…
Terra vs Vital (Junction): Health-Data APIs Compared (2026)
- Is Vital the same as Junction?Yes. Junction announced its new brand, replacing Vital, on March 11, 2025, alongside an $18M Series A led by Creandum. It is the same…
- What is the main difference between Terra and Vital/Junction?Reach and price shape, now that both sell lab testing. As of October 17, 2026, Junction offers lab ordering across all 50 US states and a…
- Can Terra and Vital both pull Apple HealthKit and Health Connect data?Yes. Terra's mobile SDK connects Apple Health, Samsung Health and Health Connect, which its docs say have no cloud API for third parties.…
- How do Terra and Vital pricing models differ?As of October 17, 2026, Terra starts at $399 a month billed annually or $499 monthly, includes 100,000 credits, and charges 200 credits a…

- Is the Fitbit API free to use?There is no published per-call fee; Fitbit is documented as free to use with the standard developer registration and approval as of 2026.…

Fitness API vs Building Your Own: How to Decide (2026)
- Is it cheaper to build my own fitness pose-tracking instead of using an API?Only the pose engine is free. Libraries like MediaPipe, MoveNet, and Apple Vision give you joint keypoints at no license cost, but rep…
- What do free pose estimation libraries like MediaPipe give you, and what do they not?They give you a per-frame skeleton of 17 to 33 joint keypoints in 2D and 3D, on-device and free. They do not give you rep counting, form…
- When should I buy a fitness API instead of building one?Buy when motion coaching is a feature inside a larger product, you need to ship in weeks, you lack a CV/ML team, you want a ready exercise…
- When does building your own fitness motion tracking actually make sense?Build when motion analysis is your core product or differentiator, you have in-house CV/ML talent, you need exercises or a clinical domain…
- Is there a middle ground between building and buying?Yes. A permissively-licensed wrapper over MediaPipe (QuickPose is one example) ships pre-built rep and form helpers, exposes raw landmarks,…
Garmin Connect IQ vs Health API vs Activity API
- Does Connect IQ give my server access to a user's Garmin data?Not the way the Health API does. Connect IQ is for code that runs on the Garmin device, optionally with a companion phone app built on…
- How is getting started with Connect IQ different from getting Health API access?Garmin's iOS companion SDK README calls Connect IQ its "open platform for third-party developer apps", and both companion SDK READMEs tie…

- Will a step challenge work on iPhones the employer manages?Not through HealthKit if the employer's MDM profile restricts it. Apple documents that an MDM profile can disable HealthKit on a managed…
- Should roster and benefits data share a pipeline with wearable data?Our recommendation is to keep them apart. Rosters and eligibility come from the employer's HR side, single sign-on from its identity…
Wearable Data Platforms for Research Studies: Fitabase, Labfront, Empatica and Ametris
- Which research platforms will still collect Fitbit data after the Fitbit Web API turns off?Of the four platforms compared here, Fitabase is the one that documents Fitbit collection. Its knowledge base says it is moving to the…
