Now that Paprika 3 has been released on iOS, Paprika 2 no longer shows up in the search results in the App Store. However, you can still reinstall Paprika 2 by looking in the Purchases section of the App Store. If you've purchased Paprika 3 you can also reinstall Paprika 3 using the same instructions.
iOS 10 or earlier: Go to the App Store, select the Updates tab, and then tap on Purchased at the top. Then scroll down to Paprika Recipe Manager and install from there.
iOS 11 or later: Go to the App Store and tap the user button in the top right corner. This will bring up your account information. From there, tap on Purchased. Then scroll down to Paprika Recipe Manager and install from there.
Make sure you are logged into the App Store with the Apple ID used to originally purchase the app, otherwise it won't be able to recognize your original purchase. For more information, see here:

In some cases we have seen apps accidentally get marked as Hidden in the App Store or Mac App Store, preventing them from showing up under the Purchases tab. If this has happened, please follow the steps here to unhide the app:

Warning: Paprika 2 is no longer being updated and we cannot guarantee it will continue to work on new versions of iOS, as Apple tends to make breaking changes with each iOS release. In particular, we have been seeing more compatibility issues since the release of iOS 13. If you want to ensure Paprika is compatible with the latest release of iOS, we highly recommend upgrading to Paprika 3.
