PowerScreenX gives parents simple, flexible control over their children's screen time. How it works: Children receive a time balance that they spend in sessions. When time's up, the device locks automatically. Parents can manage everything from their own device. Key features: • Balance-based screen time — no rigid schedules, just a time budget • Start, stop, and extend sessions remotely from the parent app • Bonus time — reward good behavior with instant extra time • Automatic device lock when session ends • Uninstall protection — the app can't be removed without parent authorization • Works offline — device stays locked even without internet • Multi-device support — manage multiple children and devices Easy setup: 1. Parent signs in with Apple ID 2. Add your child's profile 3. Link the child's device with a simple code 4. Done — start managing screen time right away PowerScreenX uses Apple's Screen Time framework to enforce limits directly on the device. A child iCloud account in the same Apple Family Sharing group is required.

SyncUp is an open-source client for the Syncthing protocol. A peer-to-peer file synchronization protocol that has been around since 2014. If you already run a Syncthing node on your computer, NAS, or home server, SyncUp lets your iPhone join the same network of devices and keep selected folders in sync. All transfers happen directly between devices you own, end-to-end encrypted with TLS 1.3. This app does not host or store your files on any third-party server. It connects only to peers you have explicitly authorized. FEATURES • QR code device pairing -> scan a peer's code or display your own. The 56-character device ID never has to be typed by hand. • Folder sharing controls -> accept, ignore, or auto-accept folder offers from peers you trust. • Live status -> folder progress, peer connection state, and incoming offers update in near real time. • Per-folder pause and resume from Settings. HOW SYNC WORKS ON IOS iOS reserves continuous background execution for a small set of app categories that SyncUp does not belong to. Sync runs in the foreground whenever the app is open, and SyncUp also registers two background tasks that the system schedules opportunistically, typically a short window or two per day, with the exact timing controlled by iOS. For an always-online node, run a Syncthing instance on a computer or home server that stays powered on. Your iPhone reconciles against it whenever it next runs. OPEN SOURCE SyncUp is licensed under MPL-2.0. The Syncthing daemon is embedded in-process and the full source code is available on GitHub. REQUIREMENTS You will need at least one other device running Syncthing (on macOS, Windows, Linux, Android, or another iOS device with this app) for SyncUp to be useful.
