Omo is a simple meditation app. A timer, a pleasing bell sound, notifications support, custom meditation session lengths and sensible defaults, silence and your mind (silence not required, the app ships with pleasing soundscapes). Inspired by the Do By Friday podcast, the app is just a meditation tool, with no recurring subscriptions, no upfront cost, and all you need to get your meditation done. Just let yourself be, and count on the app logging your mindful minutes to your Health App (only available on iPhone).
Relax.
