Lockstead helps limit access to selected apps before you lend your iPhone or iPad. Lockstead is an on-device app lock and privacy guard for the iPhone or iPad you hand to a child, friend, or family member. Choose the apps you want to protect, set a six-digit PIN, and see the current protection status at a glance. Lockstead works without an account, backend server, analytics SDK, or usage-data upload. LOCK AND BLOCK • Lock selected apps to prevent them from launching until you turn protection off. • Use category, allow-only, and Guest Mode rules. • Temporarily allow access and automatically restore protection when time is up. PROTECTION THAT FITS THE MOMENT • Schedule a daily protection window. • Use allow-only mode and category rules. • Start Guest Mode before handing over your device: only chosen apps stay available, all other apps are blocked, and everything restores automatically. • Use Lockstead Shortcuts to strengthen protection. Unlocking always requires authentication inside Lockstead. PRIVATE ACCESS • Protect settings with a six-digit PIN. • Optionally unlock Lockstead with Face ID or Touch ID. PRIVACY BY DESIGN • No account. • No server. • No advertising or analytics SDK. • No usage-data upload. Your PIN and protection configuration stay in the app’s local container on your device. FREE CORE, OPTIONAL VIP Core protection for one selected app is free. VIP adds multi-app management, advanced rules, Guest Mode, app-removal controls, premium themes, and alternate Lockstead icons. Lockstead uses Apple’s Screen Time technologies and requires Screen Time authorization. Family Controls, Managed Settings, and Device Activity are used solely to let users configure and enforce app restrictions on their own devices.

Verdict
The clearest difference is in-app purchases: JustGuard at none against App Lock's 3. App Lock's advantage is update cadence (every 2 weeks vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
