Fitness API Changes & Deadlines

Updated August 12, 2026 — new entries added as we verify them.

This is the dated record of what is changing in the fitness-API ecosystem: deprecations, deadlines, pricing-model shifts, and model freezes. Every entry is graded — confirmed means a vendor’s own words are quoted on the linked page; reported means the claim comes from vendor or community notices we could not confirm on an official page. Each entry links the page on this site that carries the sourced detail, and every date keeps the precision of its evidence rather than being sharpened for effect.
confirmed — vendor’s own words, quoted and datedreported — consistent notices, no official page verified

Subscribe once and every deadline we verify afterwards shows up where you already look. Events with no confirmed day are titled [reported month] and placed on a nominal date for planning only — the calendar carries the same grading this page does.

    Google Fit APIs: end of documented support

    Google's own documentation states Fit APIs "will be supported until the end of 2026" (verified against developer.android.com on July 31, 2026). Migration targets differ by integration shape: Health Connect on-device, Health Services on Wear OS, or the Google Health API for server-side reads.

    Fitbit → Google Health side-by-side window reported to close

    A window in which the legacy Fitbit Web API and the Google Health API run side by side is reported to extend into late September 2026 — the practical dual-read period for migrating integrations.

    Fitbit Web API turndown (reported window)

    The legacy Fitbit Web API's retirement in favour of the cloud Google Health API is reported to land around September 2026. No official day is confirmed on a page we could verify; some third-party guides name September 30, which is weaker evidence, not stronger. Tokens are reported not to transfer — every user re-consents via Google OAuth.

    Strava developer terms: Standard-tier subscription (reported)

    Strava's developer access terms reportedly changed during 2026, with Standard-tier developers said to need a paid Strava subscription. The architectural constraints matter more than the fee: athlete data may generally only be displayed back to that athlete, and using it to train AI/ML models is prohibited.

    Fitbit accounts: Google Account consolidation gate (reported)

    Users on legacy Fitbit-only logins are reported to need consolidation into a Google Account by roughly mid-May 2026, and reportedly cannot use the successor API until they do — a gate on your migration, not a detail inside it.

    WHOOP membership restructuring

    WHOOP has restructured its membership recently. Because WHOOP requires both a developer membership and an active end-user membership for data to flow, a restructuring moves two columns of the cost model at once — verify current terms before budgeting.

    Nutritionix open free tier reportedly curtailed

    Reports conflict on whether Nutritionix's open free tier still exists; higher tiers route through a Syndigo sales contact. If the free tier is gone, the freemium classification shifts toward sales-gated.

    Oura personal access tokens deprecated

    Oura deprecated personal access tokens in December 2025 — scripts and internal tools built on PATs need the OAuth flow instead. This page's phrasing has been quoted back to us in search queries, a sign assistants cite it.

    ANT+ membership and certification programs discontinued (reported)

    Per widely-quoted announcements from the ANT+ organization — the official page was unreachable in our research pass, so this stays reported — the ANT+ membership and certification programs were discontinued on June 30, 2025, with certification applications accepted only until March 31, 2025. Device profiles and documentation reportedly remain available and existing devices are unaffected; coverage cites the EU Radio Equipment Directive as a driver. For new fitness apps, BLE is the practical default radio.

    Strava tightened its developer program

    Strava tightened developer-program rules in 2024 — the start of the stricter display, branding, and access regime its API operates under today.

    MoveNet: no model updates observed since 2024

    No updates to the MoveNet pose models have been observed since 2024. The single-person models remain Apache-2.0; treat the weights as stable rather than evolving.

    Google Fit: new developer sign-ups closed

    Google closed Google Fit API sign-ups for new developers on May 1, 2024 — the first hard milestone of the Fit sunset. Existing integrations continued to work.

    MediaPipe Pose Landmarker weights: last modification

    The served MediaPipe Pose Landmarker .task model files were last modified in April 2023. The framework evolves; the pose weights have not — pin versions and treat model updates as an event, not a stream.

  • Google Health API pricing and quota model

    The Fitbit successor's pricing model is not clearly public. Until it is, the free-to-call classification of the Fitbit ecosystem is the least stable cell in our dataset.

  • MoveNet MultiPose licence gap

    The MultiPose model card we read carried no licence line, while the single-person models are Apache-2.0. Confirm independently before shipping multi-person tracking commercially.

  • Garmin developer program sign-ups

    Third parties report new partner sign-ups paused at times, with no reopening ETA. Existing partners are unaffected. Verify current status before planning a Garmin integration.
