Even though Docs To Go Premium has been discontinued, you can still install it on a new phone or reinstall it on an old one. The process is different depending on how you originally purchased Docs To Go Premium.
There are two ways you could have purchased Docs To Go Premium. One is by purchasing one of the premium features inside the Docs To Go Standard app. This is called an “in app purchase”. The other way is to purchase the Docs To Go Premium app itself.
Regardless of how you purchased the premium app, you can still use Premium on a new device or an old one that has been reset.
If you purchased via In App Purchase
You must install Docs To Go Standard from the App store. It is still available by searching or clicking here.
Once you do that, the premium features should automatically work. If they don’t, then it’s most likely because you aren’t logged in with the right Apple ID on your phone. The Apple ID that was used when you originally purchased the in app purchase MUST be what you see when you open the Settings app on your phone and then tap on your name at the top of the screen. If ads are still showing or the premium features are not available, you need to know the Apple ID you used to purchase and log in with that.
Note: Once you do that, you might need to restart the phone and/or reinstall Dos To Go Standard in order for the ads to go away and the premium features to show up.
If you purchased the Docs To Go Premium App
The Premium key won’t show up “normally” in the App Store anymore since it’s been discontinued. You need to go to the App Store and click on the icon in the upper right corner (the one that looks like a head with a circle around it) to go into your App Store account. Then go to Purchased and then My Purchases and you will see all the apps you have either purchased or downloaded. Then toggle to “Not on this iPhone” at the top of the screen, and search for Docs To Go. Once you find it, you can then download it as long as it is still compatible with the OS on your phone. The last iOS version that Docs To Go was tested on is iOS 15.4. Anything newer than that it may or may not work.
