Tac is a simple iOS app that lets you record reminders with your own voice. Record a message, choose a time or a location, and your voice will automatically play when the moment arrives. No repeating alarms. No endless notifications. Just a message from yourself at exactly the right time. Tac can be used for everyday reminders, encouragement, or even leaving voice capsules for someone that open at a specific moment or place. Tac is free to download. Tac Premium is a one-time purchase ($4.99).
