How do I re-download the old 2Do for iOS app?
The previous 2Do for iOS app, the single app that ran on both iPhone and iPad, is no longer available for new purchases. If you've already purchased it, you can still download it any time from your purchase history. It just won't show up in App Store search:
- Open the App Store and tap your photo or the My Account button at the top.
- Tap Apps & Purchase History, then Your Apps. In a Family Sharing group, tap My Apps or a family member's name.
- Tap Not on this iPhone or Not on this iPad.
- Find 2Do and tap the download button.
These are Apple's own steps, described in full in Redownload apps you bought.
Make sure you're signed in with the same Apple Account you originally bought that app with, because each purchase is tied to the account that made it. See also Can I restore an iOS purchase?
Looking for the current apps?
2Do for iPhone and 2Do for iPad are new apps with their own App Store listings, so you find them by searching the App Store as usual. They are separate purchases and do not appear as an update to the old app. See what the new iPhone and iPad apps are.
