I've been meditating for a while and got frustrated with the existing apps. They're either bloated with guided sessions I don't need, plastered with ads, or locked behind subscriptions just to use a basic timer. Also, I don't want the data to go out for farming anything funny, keep all private and safe. So I built MTimer - Meditation Timer. A clean, unguided timer for people who just want to sit and meditate without distractions - there no AI feature kind of gimmicks.What it does: Just basic timer things with added Calm scoring based on heart rate (currently testing HRV based scoring)- Meditation timer with an intuitive rotating dial and custom presets (of max 10)- Inifinity/Open ended session for experienced users. Long press in the start button to edit.- Interval bells for Vipassana, mindfulness, and mantra practice- Ambient sounds: rain, ocean waves, white noise, pink noise, bamboo flute.- Zen Mode distraction-free black screen that stays awake during your session (In any sessions, if the DND mode enabled, it will suppress any calls/notifications so you would have distraction free session)- Calm Score uses heart-rate data from your wearable to measure physiological calm after each session. All processed on-device, nothing leaves your phone.- Session history, streaks, weekly progress, and heart-rate graphs- Health Connect & Google Fit sync- Google Drive backup: no account required, no lock-in- Works completely offline- option to switch sound output for privacy- Theme support, and zen mode customizations.The philosophy: No guided voices. No social features. No ads. No subscriptions. Just a timer, bells, optional ambient sounds, and tools to support your practice. All features available for everyone.It supports mindfulness, Vipassana, mantra, breath awareness, self-inquiry, and silent sitting — with beginner guides drawn from traditional practices.Link: https://play.google.com/store/apps/details?id=com.gnaanaa.mtimer
