Best offline fitness tracker apps, 2026

Most fitness apps stop working the moment you lose signal, then ask for a subscription and an account before they'll save your data at all. The trackers here flip that: every set, run, climb, and meal lives on your iPhone, with no login and nothing synced to a server. Ironlog logs your lifts and surfaces last session's numbers plus automatic PRs and a plate calculator; PocketPlate searches a bundled 15,000-food database to count calories without phoning home; Tortoise advances its Couch-to-5K only when your Apple Watch heart rate stayed in range; and Sendlog, Baseweight, and Bikebook cover climbing, ultralight pack weight, and chain-wear maintenance for the trailheads and crags where there's no Wi-Fi anyway.

FAQ

Do these apps actually work offline? ▾

Yes. Every app on this list stores your data on-device and runs without an internet connection. PocketPlate even bundles its ~15,000-food database locally so searches work with no signal, and Baseweight loads your gear library instantly at a no-signal trailhead. There's no cloud round-trip for normal use.

Are they free, and do they require an account? ▾

None of these apps require an account, a login, or a subscription, and there's no social feed or ads. They keep your training data private on your phone. These apps are currently in TestFlight beta, so you join through TestFlight rather than buying on the App Store.

Which app should I pick for my sport? ▾

Match the app to what you track: Ironlog for strength training and PRs, PocketPlate for calories and macros, Tortoise for a heart-rate-paced Couch-to-5K, Sendlog for bouldering and route climbing plus a hangboard timer, Baseweight for ultralight backpacking pack weight, and Bikebook for bike maintenance and chain-wear tracking.
