TinyWalk: Health Test Data

TinyWalk is a developer utility for generating synthetic HealthKit test data on a real device. Building or QA-testing an app that reads step counts, walking distance, or workouts? Populating a test dataset by hand in the Health app is slow, and the iOS Simulator cannot reproduce device-only HealthKit behavior. TinyWalk writes well-formed sample data in one tap so you can exercise your read paths, charts, aggregation windows, and permission flows against realistic input. [What it writes] • HKQuantityTypeIdentifierStepCount — one sample per minute • HKQuantityTypeIdentifierDistanceWalkingRunning — derived at 0.75 m/step • HKWorkout (.walking) — wrapping the samples in a single session, so your workout-reading code has something to parse [Features] • Six dataset presets: 100, 1,000, 2,000, 3,000, 5,000 and 10,000 steps. • Provenance control: write samples tagged HKMetadataKeyWasUserEntered (as the Health app does for hand-typed values) or untagged like device-recorded data. Most apps branch on this flag, so testing that branch needs both. • Back-dated generation: spread a dataset minute-by-minute across a past time range, so you can test how your app aggregates historical data without waiting in real time. • Live generation: write progressively over a countdown, to test how your app reacts to HealthKit data arriving while it runs. • Realistic variance: samples carry ±12% per-minute variation and a configurable cadence (walk / jog / run) so your charts and averages are tested against non-uniform input instead of a flat series. • Local log of every dataset written, so you can find and clean up what you generated. • No ads, no account. Data generation happens entirely on your device — the only network request TinyWalk ever makes is if you choose to send feedback (Settings → Feedback), which posts your message and an optional screenshot to our support channel. [Important] The data TinyWalk writes is synthetic. It is intended for developing and testing your own software. Do not use it to represent real activity, and do not use it in fitness challenges, insurance or workplace wellness programs, games, or any other context where step counts earn rewards. Samples written by TinyWalk can be deleted at any time from the Health app. [Pro Lifetime Unlock] The 100-step and 1,000-step presets are free. A single one-time purchase permanently unlocks the 2,000 / 3,000 / 5,000 / 10,000-step presets and removes daily generation limits.
