Everyone tells you going outside helps. Green Hour is how you find out whether it helps you.
Check in before you head out, then again when you get back. The gap between those two ratings is your delta, and a few weeks of them add up to a picture of what time outside does for you.
HOW IT WORKS
A check-in takes about ten seconds. Tap the feelings wheel, pick up to three emotions, then rate how you are doing from 0 to 10. Start your session and put the phone away. When you come back, check in again.
Green Hour subtracts your second rating from your first. That is the whole calculation. Your emotions are never scored. No feeling here is worth more or less than any other, and the only number in the app is the one you gave it.
Over a few weeks those deltas become your Nature Delta: a rolling average of the shift, plus the patterns underneath it. Which feelings change most when you head out. What time of day works for you. How many days you got outside at all.
WHAT YOU GET
- A feelings wheel with a small set of emotions, capped at three, so a check-in takes seconds
- Sessions that start with one tap and keep running if you restart your phone
- A daily goal, 30 minutes by default, and a streak that counts the day even when you skip the check-ins
- Your Nature Delta with a trend line, a green-days calendar and time-of-day patterns
- Widgets: goal ring and streak, delta with a sparkline, and a lock-screen circular
- Apple Health import for outdoor walks, runs, rides, swims and hikes, brought in quietly, with mood optional and added later if you want it
- A daily reminder that knows how much light is left
- A monthly recap card you can share
BUILT TO BE KIND
A session with no check-ins still counts toward your streak. Days where the delta went the other way show in muted amber, and the copy takes them in its stride. There is no leaderboard.
Green Hour tracks the sun through your day and the whole interface moves with it, from morning through golden hour into a night palette that feels like standing outside after dark. It will tell you where the light is, never what the weather is doing. It cannot see the sky.
YOUR DATA STAYS ON YOUR PHONE
There is no account and no server. Your check-ins, notes and ratings sit on your device, and there was never anywhere else for them to go.
GREEN HOUR PLUS
The habit is free, forever. Logging, sessions, streaks and your headline delta are never paywalled. Plus adds full history, the emotion-level breakdown, all widgets and share cards without the watermark.
And if money is the thing standing in the way, the paywall has a "Can't afford it?" link. Tap it and Plus is yours. No proof, no email, nothing sent anywhere. Money should not decide who gets the whole picture.
Green Hour Plus is monthly or yearly, with a 1 week free trial on the yearly plan, or a one-time lifetime purchase. Subscriptions renew until you cancel, which you can do anytime in the App Store.
Green Hour is a wellbeing tool. It does not diagnose or treat anything.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Thank you for using Green Hour, the app that shows how time outside shifts your mood.
This update lets you add time outside by hand, for the time the app didn't record. Say roughly when you headed out and how long you were gone, and it counts toward your day like any other session.
Feedback is always welcome. If you have suggestions for improvements, get in touch.
