About this app

Stop being late. Start being on time.

ReadyBy is the backward planning app that tells you exactly when to start getting ready so you can leave on time, every time.

If you're always running 5–10 minutes late, rushing out the door, or underestimating how long things take, ReadyBy fixes that.

Instead of guessing when to start, ReadyBy plans backwards from your deadline and builds your schedule for you.

No guessing. No rushing. No stress.

Just follow the plan and leave on time.
________________________________________
THE MISSING PIECE OF TIME MANAGEMENT

• Most people plan forwards and hope it works.
• But punctual people plan backwards.
• They start with their deadline and work backwards to calculate when to begin.
• ReadyBy does this automatically.
• This is called backward planning (or reverse planning), and it’s the key to better time management, reliable routines, and staying on schedule.

WHY READYBY IS DIFFERENT

• Most planner apps tell you what to do.
• ReadyBy tells you when to start.
• That’s the difference between being late and being on time.
• ReadyBy is built specifically to fix lateness using backward planning — the same method used by punctual people.
• Instead of guessing… You know exactly when to begin.
• Instead of rushing… You leave calmly.
• Instead of being late… You’re ready.
• If you’re looking for a Routinist alternative, ReadyBy is actively maintained and built for modern routines.
