It happens to everyone. You’re scrolling through your home screen, looking for that one specific flight tracker or a random photo editor you used once six months ago, and it’s just... gone. Maybe you deleted it to save space. Maybe your toddler got ahold of your phone and performed some accidental digital spring cleaning. Or, more likely, your iPhone "offloaded" it because you hadn't opened it in forever.
Figuring out how do you reinstall an app on iPhone isn't actually a single process. It’s more like a "choose your own adventure" depending on how the app vanished in the first place. Honestly, half the time the app isn't even truly deleted; it’s just hiding in the App Library, which is that screen you reach when you swipe left way too many times.
The Quickest Way: Using the App Store Search
If you know exactly what you’re looking for, don't overthink it. This is the path of least resistance.
Open the App Store. Tap that magnifying glass in the bottom right corner. Type the name. If you've owned it before, you won't see a button that says "Get" or a price tag. Instead, you'll see a little blue cloud icon with an arrow pointing down. Tap that cloud.
The app starts downloading immediately. No passwords required usually, since your Apple Account already "owns" the license for it. This works even for apps you paid for five years ago. As long as you're using the same Apple ID, you don't have to pay twice.
Finding Your "Lost" Purchase History
Sometimes you forget the name of the app. You remember it had a purple icon and helped you organize your garden, but the name? Total blank. This is where the Purchased list becomes your best friend.

- Open the App Store.
- Tap your Profile Picture (or the little person icon) in the top right.
- Tap Apps (some versions of iOS still call this Purchased).
- Switch the tab at the top to Not on this iPhone.
This is basically a graveyard of every digital choice you've made since you got your first iPhone. It’s an alphabetical list of every app you’ve ever downloaded that isn't currently installed on your device. You can scroll through here until the purple garden icon catches your eye, then hit that cloud icon to bring it back to life.
Dealing with "Offloaded" Apps
Apple has this feature called Offload Unused Apps. It’s pretty smart, actually. When your storage gets tight, iOS deletes the app itself but keeps all your documents and data.
You’ll know an app is offloaded because the icon still sits on your home screen, but it has a tiny cloud symbol next to its name. If you see that, you don't even need the App Store. Just tap the icon. The phone will "re-download" the app while keeping your login info and settings intact. It’s like the app never left, it just went into a deep sleep to save you a few gigabytes.
If this keeps happening and it bugs you, head to Settings > App Store and toggle off Offload Unused Apps. Just make sure you have enough storage, or your phone will start acting sluggish.

What If the App Is Hidden?
This is a weird one. You can actually "hide" purchases so they don't show up in your history. Maybe it’s an old dating app you don't want your partner seeing, or just an embarrassing game from 2012.
To find these, you have to go a bit deeper:
Go to Settings, tap your Name at the very top, and hit Media & Purchases. Tap View Account. You'll probably have to use FaceID or your passcode here. Scroll down to Hidden Purchases.
If the app is sitting in there, tap Unhide. Now it'll show up in your regular App Store search or purchase list again.
Troubleshooting the "Will Not Install" Headache
Sometimes you hit the cloud icon and... nothing. The circle spins for a second and then turns back into a cloud. It’s frustrating. Usually, this is a storage issue. Your iPhone needs roughly twice the size of the app to actually unpack and install it. If you have 500MB left and the app is 400MB, it’s probably going to fail.
Another common culprit is a weird network glitch. Turn your Wi-Fi off and back on. Or, if you're on a massive app (like Genshin Impact or a heavy video editor), make sure you aren't trying to download it over a spotty 5G connection in a basement.
Lastly, check your Screen Time settings. If you’re on a managed device (like a work phone or a kid’s phone), there might be a restriction under Content & Privacy Restrictions > iTunes & App Store Purchases that literally forbids installing apps. If "Installing Apps" is set to "Don't Allow," that cloud icon will be your mortal enemy until you change it.
Actionable Next Steps
- Check your App Library first: Swipe all the way to the right and search. It might just be hidden from your home screen.
- Verify your Apple ID: If an app is asking you to pay again, you’re likely signed into a different account than the one that originally bought it.
- Clear 2GB of space: If downloads are failing, delete a couple of long videos from your camera roll; it usually clears the hurdle for the installer to run.
