You've tried writing things on your hand. You've tried sticky notes on your monitor. You've tried setting phone alarms, calendar reminders, and app notifications. None of them stuck.
The reason isn't that these systems are bad. It's that they all share the same flaw: they require your active participation to work.
The problem with pull-based systems
Calendars, to-do lists, and task apps are "pull-based" — you have to go to them. Check the calendar. Open the app. Look at the list. On the days you're busiest (and most likely to forget things), you're least likely to check anything.
Push-based systems actually work
The best reminder system pushes information to you, in a channel you already use, at the moment you need it. That's what a text message does. It arrives. You read it. You act on it or delay it. Either way, you've been reminded.
again is a push-based system that uses SMS. Set your tasks once — daily, weekly, monthly, or one-off — and it pushes reminders to your phone. Reply DONE or SNOOZE. The system handles everything else.
No pulling required. No checking in. No opening apps. It comes to you.
