Most apps in the Not Another Apps series do not use cloud sync.
All information is stored locally on your device and does not transfer between devices.
App data is stored only on your device. If the app is deleted, reinstalled, or the device is reset, past data cannot be recovered.
The “Not Another App” series is designed to provide clean, essential tools without unnecessary features.
Updates may refine the user experience, but complexity is intentionally kept low.
Apps developed by Andy Arevalo are tested and optimized for:
iPhone
iPad
All modern iOS versions supported by Apple
