Humans have an internal biological clock that helps them anticipate and adapt to the regular rhythm of the day, namely circadian rhythm. Scientific research has shown the importance of circadian rhythm for human health, and led to a Nobel Prize in Physiology or Medicine in 2017. Tempori is an innovative iPhone and Apple Watch app to help you schedule daily activities based on general circadian rhythms determined by daylight. It offers some timing related advices, and tracks suitability of activities at anytime, based on your schedule. On iPhone, it lets you set constrained schedules with intuitive gestures, and visualizes them as colorful arcs, together with a color-coded clock for daily variation of light conditions. Since light is the primary signal for circadian rhythm, you can study the year-round daylight conditions at your current location interactively. The watch app tracks the suitability of those activities continuously, based on your schedule. Tempori is integrated with the Apple Health app. In both iPhone and watch apps, you can record health activities and save data into the Health app. If you subscribe to premium features, you can study daily weather conditions anywhere in the world, and hourly temperatures in US. You can set travel plans to help prepare for jet lag with automatic schedule shift before the trip. Personal activity data in the Health app will be visualized together with relevant schedules, for convenient comparison. These include sleep analysis, dietary energy intake, caffeine intake, workouts, mindful sessions, tooth brushing, and hand washing events. Your historical heart rates and heart rate variability (HRV) are analyzed and visualized, to evaluate heart health and guide workout intensity. Sound levels and BMI are visualized. Tempori can recognize food text and images with the iPhone camera, and provide some nutrient information, including fish mercury levels. You can also measure correlated color temperatures of light sources. In addition, watch face complications offer gentle hints of the most important activity at anytime. If your device support Apple Intelligence, you can chat with AI on device privately. In summary, Tempori takes advantage of and enhances Apple Watch's essential function: timing. It will help you build habits for health and productivity. ## Key features - Circadian rhythm scheduling - Daylight condition visualization - Activity suitability tracking - Apple Health integration - Jet lag preparation - Health data visualization - AI-powered chat (on-device) ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Monthly subscription | $0.99 | per month | | Annual subscription | $9.99 | per year | ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/tempori/id1459036481/reviews.md ### 1/5 — Nothing on circadian rhytms *2020-10-22, version 2.7* This app is super cheap, yet it should be free because it gives you absolutely nothing useful for your $1.39. I already know not to drink coffee after 6pm and that i’m most productive before 6pm, everybody does. It doesn't show you the up and down cycles that change throughout the day to guide you. Wasted a dollar. Forget about a subscription. ### 4/5 — Cool Idea that Needs to be Fleshed Out *2019-11-06, version 1.6* This is one of the few apps that I wish actually had notifications. It’s nice to be able to use this as a planner, but it’s pretty bare-bones. I’m looking forward to seeing where this app goes. It has a lot of potential. ### 1/5 — Disappointing *2019-09-14* Whilst the app is well presented and is easy to understand, I was really disappointed overall. You merely select you bedtime, meal times, etc... a calendar appointment will offer the same functionality. There is nothing clever or intuitive with regard to your own unique body clock, which was the impression the description and the website game me. **Developer response:** Lighting is the primary signal for body clocks. There is more commonality than differences among people. Better to schedule based on sunlight and manage other light. Current useful features of the app include Apple Watch complications that serve as gentle reminders, study of year-round sunlight with time-travel, and guided (constrained) scheduling with gestures. ### 1/5 — Useless *2019-07-13* Waste of money. Extremely limited. It will not worth even a penny **Developer response:** The app and the approach behind it are simple but effective. It's extremely difficult to change habits. Recurring reminders on the watch are helpful. ### 1/5 — I paid for this *2019-06-06* The app has no value. It does nothing, nothing. **Developer response:** It takes determination and patience to build healthy habits and see good results. This app’s watch complications gently remind and nudge users in the right direction. Should be able to help many users. ### 5/5 — Genius *2019-05-16* That’s a genius way to know what to do at a certain time of the day. Got try it out. ## Frequently asked questions about Tempori ### What is Tempori?
