AvaDebt
Plan clearly. Move forward.
AvaDebt can be added directly to your iPhone Home Screen from avadebt.com. It opens full-screen, keeps the same account, and avoids the App Store while the product is growing.

Added to Home Screen
Full-screen app feel
Once installed, AvaDebt opens without the normal Safari address bar, while still using the website underneath.

The Share button is usually at the bottom of Safari. It looks like a square with an arrow pointing up.
Keep the name as AvaDebt, then tap Add. The AvaDebt icon will appear with your other apps.
It will launch in a full-screen app view without the normal Safari browser bar.
Why this works well first
This lets you test the real phone experience with members before deciding whether an App Store version is worth the extra cost and review process.
No App Store download required
No Apple developer account needed for members to install it
Works from the same secure AvaDebt website
One app experience for desktop, tablet, and iPhone
The PWA route itself does not require Apple’s yearly developer fee. The main cost is normal website hosting for avadebt.com.
No. This uses the same AvaDebt app and the same saved account data. The iPhone icon is simply a cleaner way to open it.
Possibly. AvaDebt can start as a PWA first, then move to App Store packaging later if the app needs native iPhone features.
Open this page from Safari on your iPhone, then use Share and Add to Home Screen. After that, open AvaDebt from the icon.
