# TempoLife > TempoLife is an Estonian health diary: snap a meal photo, get an editable AI calorie estimate, and track food, weight, sleep, steps and fasting in one place. Free to start on Google Play. There is no iPhone app, but the web app works in any browser including iPhone Safari, where it can be added to the Home Screen. Not a medical device. TempoLife helps people keep a food and health diary with minimal effort. The AI suggests visible foods and portions from a photo; every estimate is user-editable before it is saved. Data is stored on servers in the EU; users can delete their account and data at any time. ## Guides - [Photographing food for better AI calorie estimates](https://tempolife.app/article.php?p=photo-food-calories&lang=en): light, angle, one meal per photo — practical tips for a more accurate calorie and macro estimate. -
