Sorry about that. These steps fix most crashes on launch.
- Close it fully and reopen. Swipe up from the bottom of the screen, swipe just streak away, then open it again.
- Update the app. Open the App Store, search for just streak, and tap Update if it's there.
- Update iOS. Go to Settings › General › Software Update.
- Restart your iPhone.
- Free up some space. A nearly full iPhone can stop apps from opening properly.
Thinking of reinstalling? Check first whether you have an account. If you do and your habits have synced, you'll get everything back by logging in. If you're using the app as a guest, deleting the app deletes your habits too, and we can't restore them.
If the app opens but shows Oops, something went wrong, note the error code on that screen. See Where do I find my support code?
Still crashing? Contact us with your iPhone model, iOS version, and what happens right before it closes. We're on it as soon as we hear.
