Wizabee

Your music follows your steps. Wizabee changes the tempo of your music to match your walk. Highlights - Follows your walking tempo: footfalls are detected on your iPhone, and playback speed is matched to the tempo of your walk. The pitch never changes. - Even volume across songs. - Walking feel: how fast the music catches up, and where it lands. - Playlists: mix the included songs with your own, up to 200 per list; free: 1 list, Plus: unlimited. - Five original tracks for walking; try each in the Store. - Apple Watch (optional): your watch measures your heart rate on walks started on iPhone; above a limit you choose, the tempo slows more the further above. The limit is only your own guide. - Health (optional, off by default): save walks as workouts. - Lock Screen, Dynamic Island and Siri: time, distance and tempo as you walk. "Start a walk" and "End a walk" work from Siri, Shortcuts and the Action button. - Tempo Plans (optional): 10–30 min plans where the music tempo changes a little at set times, around your easy walking tempo; the target tempo (SPM) is shown on screen. Free: 2 plans. Wizabee Plus: all 8. - History tab: month totals and a calendar; tap a walk for a graph, per-km splits and a slope path. Or choose "GPS with map" in Settings (off by default) for a map route: While Using location only; the route is not sent to Wizabee's servers; the map is shown with Apple Maps; first and last 200 m hidden. Pricing - Plans and prices are shown in the app; the in-app Store also explains the included songs and Wizabee Plus (subscription). - Your own songs (iOS 27 or later): how many songs you can add for free, and how long each can be, is shown in the app. With Wizabee Plus, there's no limit on the number of songs. - Wizabee Plus renews automatically unless you cancel. If a free period applies, the paid period begins automatically when it ends. Cancel in Settings > your name > Subscriptions at least 24 hours before the period ends to stop renewal. - If your subscription ends, no song is deleted: the free plan's limits then apply, as shown in the app. Subscribe again to use them all. - Terms of Use (Apple's standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - Privacy Policy: https://kyota1123.github.io/wizabee-privacy/en/ Your own music (iOS 27 or later) - Add your own audio files (MP3, AAC, WAV, AIFF, ALAC, FLAC; length limits are shown in the app) and walk to them. - Add songs from the Music app, from the Files app, from the share sheet, or by putting them in the Wizabee folder under "On My iPhone". - Streaming and copy-protected songs can't be used; from the Music app, songs not yet downloaded don't appear either. Songs are converted to CD quality if needed. - Each song gets a free check ("Ready to add", "Not sure", "Can't be used") and waits as "Not added yet" until you tap Add. - The rhythm of your songs is checked on your iPhone. The audio, the title and the file name never leave the device. - In Japan only: Collaborator Mode is optional (off by default); all else, Plus included, works without it. If you join and consent, we get records such as your walks (each step's time), rhythm checks, whether a song came from Music or Files, and when it played; never titles or file names. Heart rate (on walks using the limit) and route info (no coordinates) are sent only if you turn on their switches (heart rate also needs separate consent). As thanks, contributors can add up to 20 own songs (up to 10 min each); if you stop without Plus, the free plan's limits apply; no song is deleted. You can ask us to delete what you sent (done within 30 days). Privacy - No account and no sign-in. - Health data stays on your devices, except as noted above. - We do not collect your name, location, audio, or advertising identifiers. - Walk data is sent only in Collaborator Mode (Japan only, off by default); else just a random value for the song of the month. Take your usual walk, at your own rhythm.
