You can't literally move an app to iCloud — iOS keeps installed apps on the device. But you can free the space an app uses two ways: Offload Unused Apps (Settings > App Store, or per-app in iPhone Storage), which removes the app's files but keeps its data; and storing an app's documents in iCloud Drive so the files live in the cloud, not on your phone.
"Moving apps to iCloud" — what actually happens
iOS has no feature that relocates an installed app to iCloud. An app's program files always live on the device while it is installed. What people usually want when they search for this is to reclaim the storage an app is using without losing their progress or files. There are two real ways to do that, and they target two different things: the app itself (offloading) and the app's data and documents (iCloud Drive / per-app iCloud sync).
Offload vs. delete vs. iCloud data — at a glance
| Action | Removes app files? | Keeps app data? | Frees space? | Reversible? |
|---|---|---|---|---|
| Offload app | Yes | Yes (documents & data stay) | Yes (the binary) | Yes — tap icon to re-download |
| Delete app | Yes | No (data erased) | Yes (binary + data) | Only by reinstalling fresh |
| Store data in iCloud Drive | No | Yes (in the cloud) | Yes (local document copies) | Yes — files re-download on demand |
How to offload an app (keep the data, free the space)
Offloading deletes the app's program files but leaves its documents, settings, and a grayed-out Home Screen icon in place. Tap the icon later and iOS re-downloads the app, restoring everything exactly where you left off — as long as the app is still on the App Store.
- Open Settings > General > iPhone Storage.
- Wait for the list of apps to load (sorted by size makes the biggest offenders obvious).
- Tap the app you want to offload.
- Tap Offload App, then confirm. The "App Size" is freed; "Documents & Data" stays behind.
Turn on automatic offloading
To let iOS handle this for you when storage gets tight:
- Open Settings > App Store.
- Scroll to Offload Unused Apps and toggle it on.
iOS will then automatically offload apps you haven't opened in a while, but only when free space runs low — and always keeping their data so a reinstall picks up seamlessly.
How to store app data and documents in iCloud
The second half of "moving apps to iCloud" is moving the files an app creates into the cloud. Many apps support iCloud Drive or their own iCloud sync, so documents live in iCloud and your phone keeps lightweight on-demand copies.
- Open Settings and tap your name at the top to open your Apple Account.
- Tap iCloud, then See All under "Saved to iCloud" (or "iCloud Drive").
- Toggle on iCloud for each app you want to sync. Apps that store documents here (Files, Pages, Numbers, and many third-party apps) will keep their data in iCloud Drive.
- Inside an app, look for an iCloud or "Sync" option in its own settings — note-taking, photo-editing, and document apps often have their own toggle.
Once data is in iCloud Drive, iOS can offload local copies of files you haven't opened recently and re-download them when you tap to open. This is different from offloading the app — here it's the documents living in the cloud.
What about photos and videos?
Offloading apps does nothing for your camera roll, which is usually the biggest storage hog. To shrink that, turn on Optimize iPhone Storage under iCloud Photos, or simply delete the photos you don't need. Reviewing thousands of photos one by one is tedious — Swype Photo Cleaner turns it into quick left-to-delete swipes, all on-device with no uploads.
