Chime

Chime is a privacy-first SMS app for Android. A classifier on the phone sorts every thread into Personal, OTP, Banking, Promos, Carrier, or Spam, and retrains locally when you correct it. It spots dates and times in texts and offers one-tap reminders, copies OTPs straight from the notification, schedules messages with a SIM choice on dual-SIM phones, and lets you build your own categories. No account, no ads, no telemetry, and nothing is uploaded. $2.99 once on Google Play. Built by Sharan Shrivatsav.
