Set Zenith as your default launcher
Making Zenith your default launcher means it becomes your home screen: the Home button and the home swipe bring you back to the sky. You can undo this anytime, so it's safe to try.
Set it during the welcome
- Open Zenith. The welcome appears on first launch.
- Go to the "make zenith your home" step.
- Tap "set as default →".
- In the system prompt, choose Zenith as the Home app and confirm.
Zenith is now your home screen.
Set it later, if you skipped the welcome
If you skipped that step, your phone's own Settings still let you switch home apps — look for the Default apps → Home app (sometimes "Home screen") choice and pick Zenith. The exact path differs by phone brand; see the per-brand notes in Set-default won't stick / getting back to default.
How to tell it worked
Press the Home button. If you land on the sky, Zenith is your default. Zenith also confirms it with "zenith is your home launcher" on that welcome step once it's set.
To switch back
You're never locked in: reopen your phone's Default apps → Home app setting and choose your old launcher. Zenith won't stop you.
