Set your times and start. Kind Timer is a simple interval timer that alternates exercise and rest, or running and walking. • Choose activity time, recovery time and repetitions • Save your favorite settings as reusable timers • See remaining time and the next interval in large, clear text • Hear guidance while the screen is locked • Choose female or male voices in 11 languages, or simple tones • Automatically keep completed and stopped sessions • Browse compact history and delete selected entries • All features without accounts, ads or in-app purchases Settings and history stay on your device and may be lost if you uninstall the app. Every voice cue is included, so no internet or separate voice download is needed. Check media volume and the timer status after calls or disconnecting headphones. Force-closing the app stops guidance. lalajoo71@gmail.com
