How to choose an offline fitness tracker

"Offline" is easy to claim and easy to fake: many apps work without signal for a session, then refuse to save until you sign in and sync. Before you commit a year of training data to an app, check four things:

  1. 1. Does it save without an account?

    Install it in airplane mode and log a workout. If it asks you to create an account first, it is not offline; it is cached. The apps on this page store every set, run and meal on the phone with no login.

  2. 2. Is the food or exercise database bundled?

    A calorie tracker that looks up every food online is useless at a trailhead café. Look for a bundled database (PocketPlate ships 15,000 foods on-device) or a lift log that does not need a server to know what a barbell is.

  3. 3. Can you get your data out?

    Free is only free if the export works. Check for CSV or a plain-file export before you have six months of PRs locked inside an app you cannot leave.

  4. 4. What is the recurring cost?

    Subscriptions in this category run $60 to $120 a year, usually for coaching and social features. If what you want is a log, pay once or nothing. Every app on this page is free or a one-time purchase.

The longer answer

Plenty of fitness apps need a signal to save a workout, and many ask for an account before they store anything. The trackers here keep working at the gym in the basement, on the trail and at the crag. Apple's Workout app on Apple Watch and the Fitness app on iPhone log workouts with no extra account and store them in Health. FitNotes on Android is free and ad-free and keeps its log on the phone, with optional Google Drive backup. Strong is a fast lifting log across iPhone, Android and Apple Watch; it asks every user to create an account so workouts back up to Strong Cloud. Our apps keep every set, run, climb and meal on your device with no login. Form Coach, on the App Store and Google Play, checks your exercise form with the camera, on the phone. Ironlog logs your lifts and surfaces last session's numbers, automatic PRs and a plate calculator; PocketPlate counts calories from a bundled food database; Tortoise advances its Couch-to-5K only when your heart rate stayed in range; and Sendlog, Baseweight and Bikebook cover climbing, ultralight pack weight and chain-wear maintenance for places with 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. Form Coach is on the App Store and Google Play; the others are currently in TestFlight beta, so you join those through TestFlight.

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, Bikebook for bike maintenance and chain-wear tracking, and Form Coach for checking exercise form with the camera.
