Restore lost app

Greetings Michael-GR,

To help troubleshot, check and see if the app is hidden in your Apple ID purchase history. Check out those steps here:

Hide purchases from the App Store - Apple Support

"Unhide apps on your iPhone, iPad or iPod touch

If you've deleted an app from your iPhone, iPad or iPod touch, the app won't reappear automatically on your Home Screen when you unhide it. Instead, re-download the app from the App Store. You won't need to buy the app again.

1. Open the App Store app.
2. Tap the account button , or your photo or initials, at the top of the screen.
3. Tap your name or Apple ID. You may be asked to sign in with your Apple ID.
4. 
5. Scroll down and tap Hidden Purchases.
6. 
7. Find the app that you want, then tap Unhide.
8. To return to the App Store, tap Account Settings, then tap Done.
9. Search for the app, then tap the download button ."

Let us know if that helps.

Kind regards.

Hi Michael-GR,

Question. When you looked through your previous purchases, did you search through the older ones also? Since it was an older app, we want to make sure you've gotten through all app purchases. Here's how:

Find information about older purchases

If you can't find an item in your purchase history at reportaproblem.apple.com, check the purchase history in Settings on your iPhone, iPad, or iPod touch. Or check the purchase history in Account Settings on your computer.

1. On your iPhone, iPad, or iPod touch

2. Open the Settings app.

3. Tap your name, then tap Media & Purchases. 

4. Tap View Account. You might be asked to sign in.

5. Tap Purchase History.

Your purchase history appears. Tap Last 90 Days, then select a different date range.

If you've made it through all purchases, could you have used a different Apple ID? If you had a previous Apple ID, and made a new one instead of changing the email address used, that would explain why you can't find it. Purchases from separate Apple IDs can't be merged.

Normally we'd advise to contact the app developer. However, they may not be reachable, as the app was removed from the App Store.

Take care!
