Free tools for forgetful brains
No sign-up. No data collected. Built for brains that forget.
Forgetting things costs more than you think. Missed appointments, lost items, wasted food, and blown deadlines add up fast. These tools help you see the patterns and understand how your brain handles time, reminders, and follow-through.
Each tool draws on peer-reviewed memory and time-perception research. Take any of them in under 2 minutes, get your results, and share with friends or your care team. Everything runs in your browser. Nothing is stored or sent anywhere.
Whether you forget appointments, miss deadlines, or lose track of time more than most people, these tools give you a concrete starting point. Numbers are easier to act on than vague feelings.

Why we built these
Most tools like these online are either locked behind paywalls or designed to collect your email. We wanted something different: genuinely useful tools you can take right now, share with someone you trust, or send to a friend who doesn't understand why you keep forgetting things.
Bumbi started as a reminder app for people whose brains ignore regular notifications. We built these tools for the same reason: to help forgetful brains understand themselves better, one tool at a time. If the results are useful, Bumbi is free on Android.
