Six new characters join Mochi on your wrist. - Meet Macaron, Puffy, Croissy, Tirammy, Donny and Nattie. Mochi is no longer alone on your Apple Watch. Pick the character you like best and he'll show your stress in his own way, both in the watch app and in the watch face widget. You can preview each one before you decide. - Your state right on the watch face. Add the Mochi widget and check in without opening anything. We've included a step-by-step guide, illustrated with real screenshots. - Mochi now tells you what drives your stress. He reads through your data and names the likely causes instead of leaving you to guess. - A full week of history, on any day. History now shows your last 7 days instead of the current calendar week, so you get the whole picture on a Monday rather than a single bar. Every day is coloured by its stress level, so a hard stretch stands out at a glance. - Your history survives a reinstall. New phone, or reinstalled the app? Mochi rebuilds the past 30 days from Apple Health instead of starting from scratch. - Rate Mochi and reach support straight from Settings. - Fixes and polish. A completed purchase now unlocks everything right away, Mochi no longer interrupts your music or podcasts, HRV and resting heart rate load correctly when you scroll further back, and buttons are easier to tap across the app. We're continuing to refine Mochi to deliver a more consistent and reliable experience across iPhone and Apple Watch. As always, you can reach us at support@99wrongturns.com

Thank you, Mochi is a little pink in the cheeks right now. Cute was the easy part. Helpful was the one we worried about, so it means a lot to hear both. If there's ever something you'd like him to notice, we're at support@99wrongturns.com. We read every message.
Mochi visualizes your body's stress levels and physiological data, like HRV and resting heart rate, through an animated character. It aims to help you understand your stress patterns and adopt habits for improvement.
Mochi uses your HRV and resting heart rate data from Apple Health to reflect your current stress state. It compares your readings to your personal 7-day baseline for more relevant insights.
Mochi is currently designed for iPhone running iOS 17.6 or later. An Apple Watch is recommended for live HRV data, but the app can be used on iPhone alone.
No, Mochi does not contain advertisements. The app is free to download and offers an optional Pro version through a subscription for full features.
Mochi prioritizes privacy by not requiring an account, not using the cloud, and not tracking users. All your data stays on your iPhone.
Mochi Pro offers monthly and annual auto-renewing subscriptions. These can be managed and canceled through your Apple ID settings at least 24 hours before the current period ends.
The latest version of Mochi is 1.0.3, last updated on June 14, 2026. Updates are released to improve functionality and add features.
