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.
