Jon's Reminders is a text message based reminder service that allows users to send reminders to a dedicated phone number using plain English. The service then sends a text message back at the specified time. It is designed to work on any mobile phone capable of sending and receiving SMS, requiring no app installation or login for daily use. The service uses a verified toll free sender and offers a 30 day money back guarantee. The service includes several key features. Users can set one time reminders, repeating reminders on a daily, weekday, or weekly schedule, and "til done" reminders that automatically resend after 10, 20, and 40 minutes until the user replies with "DONE". The service does not send nudges between 10pm and 8am. Users can manage reminders entirely by text, including snoozing, rescheduling, and marking tasks as complete. A web based calendar and dashboard provides an overview of all reminders, showing which are done, missed, or snoozed. The service also supports reminding one other person, with built in consent. The typical workflow involves three steps. First, the user sends a text message describing what to remember and when to the service's number. Second, if the time is ambiguous or missing, the service sends a clarifying question. Third, the reminder text arrives at the correct time, and the user can reply to snooze, mark it as done, or let it expire. The service costs from $6.99 per month and can be canceled at any time.
