Beta tester guide
Comfort on timing, not the thermostat.
What Thresho does
Thresho tells you the right moment to open or close your windows, so your home stays comfortable without reaching for the thermostat. It reads your local forecast, predicts when the outdoor temperature crosses your comfort thresholds, and tells you the moment to act.
When outdoor air quality is poor, it holds the open-windows alert. If air-quality data is unavailable for your area, alerts run on temperature alone.
No account required. Thresho collects anonymous usage to improve alert timing, and you can turn it off in Settings. Free beta, iPhone, US only.
What you need
- An iPhone on iOS 17 or later.
- A home in the US.
How to join
- Install TestFlight (free) from the App Store. TestFlight is Apple's app for trying betas.
- On your iPhone, open the beta link: https://testflight.apple.com/join/J8HPyFnZ
- Tap Accept, then Install.
- Open Thresho, grant location and notifications, and set your home.
Your first run
Grant location (used to fetch your local forecast, never tracked), review your forecast, confirm your open and close rules, and turn on notifications. That is it. Thresho does the watching.
One open alert and one close alert stay switched on
Try to switch off your last one of either and Thresho will decline, and explain why. The pair is what timing means: watching one edge tells you when to open and never when to close, which reads as the app being broken rather than as something you turned off.
There are two ways to get what you were probably after. If a rule alerts too often, change its temperature. If it arrives at a bad hour, use quiet hours. Both of those keep the loop intact, which is why they are the answer.
Press and hold an alert
When an alert arrives, press and hold it to reveal Opened and Closed, then tap one. iOS hides those buttons behind a long press, so almost nobody finds them, and without them we cannot tell whether our timing is any good. If they feel hidden, say so, and tell us where you would expect them instead.
When nothing is coming, Thresho tells you why
A quiet day used to show a green checkmark that implied all was well. You will now get the actual reason: too hot all day, too cool, already comfortable, or something in your setup, sometimes with a one-tap fix.
A day with no alerts is a normal state rather than a fault, and it is worth checking: does the reason match what the weather actually did?
What we would love you to test
- Setup. Did onboarding make sense? Could you grant location and notifications without getting stuck?
- The glance test. Open the app. Within a couple of seconds, can you tell what to do: open, close, or wait?
- The alerts. Did they actually arrive, and did they come a little before the change, with enough notice to act? Reliability here matters most to us.
- Acting on it. Did you open or close when Thresho told you to, and how often? This is the single most useful thing you can tell us.
- The payoff. When you acted, did your home actually feel cooler or stay ahead of the heat?
- Anything else. Anything confusing, slow, or wrong, and any crash.
How to send feedback
- In TestFlight, take a screenshot and attach a short note. That is the fastest way to flag a bug.
- Or email hello@getthresho.com. Short notes are perfect. We read everything.
One note on safety
Forecasts can be wrong, delayed, or unavailable, so always check the real conditions outside and use your own judgment. Please do not rely on Thresho for health, safety, or emergency decisions, especially during extreme heat.
