RENN puts your whole day on one calm screen. Your classes, deadlines, workouts, meals, weather and your team's next game are all on one dashboard, so you stop jumping between six different apps. Works with Google Calendar and Apple Calendar, including iCloud and any other account on your iPhone. Choose which calendars show up, add events to one or several at once, and remove them just by asking. Connect Apple Health to see your activity, sleep and readiness, log workouts with AI training plans, and track protein, calories, carbs and fat. Built by a college student for students who want their day organized without the noise. WORKS WITH APPLE HEALTH With your permission, RENN reads your activity, sleep, workouts, resting heart rate and HRV from the Health app (HealthKit) to show them on your dashboard and check off your gym day automatically. RENN never writes to Apple Health. ADD ANYTHING IN PLAIN ENGLISH Type or say "chem exam next Friday 2pm" and RENN puts it on your calendar. It handles repeating classes, locations and reminder times too. Or just say "Hey Siri, add to RENN."
