However, multiple users report significant issues on the Android version, particularly with music selection and playback, missing features compared to iOS, and annoying pop-ups. The text-to-speech limitations and occasional crashes or UI annoyances like auto-rotation decrease usability. Overall, it remains a useful app but has several usability and feature gaps on Android that affect the experience. ### Pros - Highly customizable and versatile for different types of workouts and interval timers. - Voice prompts are useful and help guide workouts effectively. - The app supports customization of colors, workout structures, and routines, providing good organization. - Works well for various activities including fitness, yoga, meditation, and even productivity timing. - Generally easy to use and praised for flexibility and built-in workout structures. ### Cons - The app's music playback and selection features are problematic; users report issues selecting audio and lack of control over music folders or background music volume. - Android version lacks features and updates compared to the iOS version, including missing support for Galaxy watches and deprecated sound settings for new workouts. - Annoying frequent pop-ups such as rating prompts and exit confirmations that cannot be disabled. - Text-to-speech function only announces exercise names in pre-made workouts, not in custom ones, which is misleading to users. - The app tends to crash or not save/resume timers when navigating away, and screen auto-rotation during timers is considered annoying with no option to disable it. ## Similar extensions and apps - [Seconds Interval Timer](https://chrome-stats.com/d/com.runloop.seconds.free) — 1,115,086 users, 4.38 / 5 - [PRO INTERVAL TIMER](https://chrome-stats.com/d/com.rabbithouse.prointervaltimer) — 198 users - [Interval Timer - HIIT Tabata](https://chrome-stats.com/d/com.benchapps.intervaltimer) — 5 users - [Interval Timer - HIIT Workout](https://chrome-stats.com/d/com.kenley.intervaltimer) — 281 users - [Interval Timer - TimeToTrain](https://chrome-stats.com/d/com.dc.intervaltimer) — 74 users - [Power Interval Timer](https://chrome-stats.com/d/com.zuki.apps.powerintervaltimer) — 72 users - [Interval Timer: HIIT & Tabata](https://chrome-stats.com/d/com.shpavda.interval_timer) — 7,609 users - [Sport Timer Pro: Interval HIIT](https://chrome-stats.com/d/com.justtrain.sporttimerpro) — 560 users - [SportTimer](https://chrome-stats.com/d/com.shaileshpathak.sessionapp2025) — 36 users - [Tabata timer HIIT PRO](https://chrome-stats.com/d/com.tabata2.machy1979ii.tabata2noads) — 129 users - [Premier Tempo](https://chrome-stats.com/d/io.cadenceforge.tempopulse) — 18 users - [Tabata Timer and HIIT Timer](https://chrome-stats.com/d/com.parabolicriver.tsp) — 1,173,272 users, 4.79 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.runloop.seconds)
