Sift vs App Lock

Sift is a privacy-first SMS filtering app for iPhone, built to make your inbox quieter and easier to control. Sift uses the iOS message filtering extension to classify junk, promotions, and important notifications directly on your device. By default, filtering does not send message contents to a server. Your custom rules, local statistics, and on-device personalization stay on the device. Key features - On-device SMS classification for spam, promotions, verification codes, delivery updates, banking notices, travel alerts, and more - Custom sender or message-body rules - Category mapping that redirects selected categories to Promotions or Junk - Private statistics that count categories without storing message text - Optional sample contribution with an on-device redaction preview, export, and deletion controls - Sift Premium: a one-time purchase that unlocks an on-demand multilingual Transformer model Sift is not a fraud-prevention guarantee. SMS classification is probabilistic and can make mistakes. For payments, accounts, verification codes, or other important messages, always verify the original message and official channels.

Lock the apps you do not want others to open. Lockstead helps you restrict selected apps on your own iPhone or iPad using Apple Screen Time. Choose apps to block, enable protection, or set weekdays and times for restrictions. Protect access to Lockstead settings with your six-digit PIN and optional Face ID or Touch ID. VIP GUEST MODE Choose specific apps, select a duration from 15 minutes to 12 hours, and confirm the session. Lockstead applies an allowlist to supported apps through Screen Time. Try opening an allowed app and a restricted app before handing over your device. CHOOSE, APPLY, CHECK Block selected apps, set protection schedules, or temporarily allow access. Guest Mode takes priority over normal lock and temporary-access rules. When it ends, Lockstead reapplies the rules for that time; it does not simply unlock everything. iOS background scheduling can delay changes. FOR EVERYDAY HANDOFFS Let a friend use a map or lend your iPad for reading, with the apps needed for that session. Content inside allowed apps remains accessible. Guest Mode does not create a separate user account or separate app data. FREE CORE, OPTIONAL VIP Core protection for one selected app is free. VIP adds multi-app management, Guest Mode, advanced rules, app-removal controls, themes and alternate icons. Choose a monthly or yearly auto-renewing subscription, or a one-time lifetime VIP purchase. Prices are shown by your regional App Store. SETTINGS ON YOUR DEVICE Protect access to Lockstead with a six-digit PIN and optional Face ID or Touch ID. No app account, developer backend, advertising SDK or analytics SDK. Protection settings stay on your device; purchases use Apple services. Requires iOS/iPadOS 17 or later and Screen Time authorization. Availability and enforcement depend on iOS. Restrictions do not encrypt files, guarantee hidden icons or suppress notifications. This is not remote device management.
