Check that your iPhone or iPad isn’t set to silent mode and that the sound pack volume in the app is turned up. ### Why did background playback stop when you switched apps? Make sure background app refresh is allowed for “HIIT Timer Pro” in Settings, since disabling it can interrupt background playback. ### How do you restore your subscription after reinstalling the app? Open “HIIT Timer Pro”, go to the upgrade screen and use the “restore purchases” option to bring back unlimited workouts, full history and cloud sync. ### Why can’t you start a new session after your free sessions are used? Once your 20 free sessions are used, a subscription is required to continue with unlimited workouts, full history, cloud sync and an ad-free experience. ### Why isn’t your workout history syncing across your iPhone and iPad? Cloud sync is part of the upgraded plan, so confirm your subscription is active and that you’re signed in with the same Apple account on both devices. ### What is the latest version of HIIT Timer Pro, and how do I update? The latest version is 1.3, released on June 14, 2026. To update, open the App Store, tap your profile picture, pull down to refresh, then tap Update next to HIIT Timer Pro. You can also turn on automatic updates in Settings › App Store. ### How do I manage or cancel my subscription? Subscriptions are managed by Apple. Open Settings, tap your name, then Subscriptions, and choose HIIT Timer Pro to change or cancel your plan. Cancel at least 24 hours before renewal to avoid the next charge; deleting the app does not cancel it.
