Apps, websites, photos and private browsing. Keep your privacy in your hands. QwikLock combines an on-device encrypted photo vault, app and website access controls, and a separate private browser. PRIVATE PHOTOS Import photos, videos and Live Photos, or take photos with the private camera. Vault originals and thumbnails are encrypted locally. Organize albums, favorites and captions; search, browse full screen, edit still photos, select multiple items and export to Apple Photos. Recently Deleted lets you recover private copies or permanently delete them. Imports keep Apple Photos originals by default. Removing a system original requires separate confirmation after the private copy is saved and verified. Check Apple's Recently Deleted when cleaning up originals. Vault storage is local, without cloud sync: export what you need before uninstalling or changing devices. The library closes when QwikLock enters the background. PRIVATE BROWSER Browse HTTPS websites, search, manage tabs and favorites, share links and use full screen. Browser spaces keep their browsing sessions separate. You can add your own supported proxy configuration; QwikLock does not sell a proxy service or provide a system-wide VPN. Browser sessions are temporary and do not replace normal Safari history. Closing or clearing a session removes its browsing data. APP AND WEBSITE ACCESS Choose apps, categories and websites with Apple's Screen Time picker. Organize spaces, manage restrictions and supported time and location rules, and review temporary access before verifying your credential and choosing a duration. Handover check helps review current restrictions and temporary sessions before lending your phone. Enforcement depends on Screen Time authorization and iOS scheduling. App restrictions do not hide notification previews or encrypt other apps' data. FREE AND PRO App, website and space management and basic private browsing are available free. The free vault allows 99 items total, including Recently Deleted. Pro removes the vault item-count limit, offers more browser spaces and saved proxies, and provides Emergency password and optional browser clearing after a valid emergency login. Available device storage still applies. An emergency login opens a separate QwikLock workspace; it is not an iOS guest account. Cleared browsing data cannot be restored by normal login. Subscription expiry preserves saved media and app settings. Pro is an auto-renewable monthly or yearly subscription. Apple displays the current storefront price and billing period before purchase. Payment is charged to your Apple Account. Unless canceled at least 24 hours before the period ends, subscriptions renew and renewal is charged within the preceding 24 hours. Manage or cancel in Apple Account subscription settings. Restore Purchases is available in QwikLock. Deleting a QwikLock account does not cancel an Apple subscription. 13 interface languages: English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Italian, Brazilian Portuguese, Indonesian, Vietnamese and Thai. Adaptive layouts support compact iPhone and unfolded iPhone Duo. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Support: https://qwiktools.app/contact/

Verdict
The clearest difference is in-app purchases: Flash Doc Scanner at none against QwikLock's 2. Flash Doc Scanner also leads on iOS requirement (14 vs 26.0). QwikLock's advantage is update cadence (every 5 days vs every 2 months). On price, ads and device support there is nothing between them.
