Say it once. WhisperAct turns it into reminders, calendar events, and todos — in Apple Reminders and Apple Calendar, where you already look. "Dentist Tuesday at 10, remind me to email the landlord Friday, pick up milk" becomes three items, correctly dated. No retyping. SPEAK ONCE, STAY ORGANIZED Talk naturally. WhisperAct works out what you meant and files it in the right place — understanding "next Friday", "after lunch", "in two hours", and "end of the month". Prefer typing? That works too.

Your brain isn't built for holding onto things. BrainBuffer is. Open the app, type a thought, tap send. That's it — no folders to choose, no categories to pick, no setup standing between you and getting something out of your head. Simply effective. CAPTURE WITHOUT FRICTION Just type. BrainBuffer strips away every extra step between having a thought and having it safely out of your head. DATES THAT WRITE THEMSELVES Type "call mom tomorrow" or "email the client in three days" and BrainBuffer picks up the timing automatically — no date picker required. Need something more specific? Tap the calendar icon to set an exact time instead. A LIST THAT SORTS ITSELF Unfinished thoughts float to the top. Pinned ones lead the pack. Anything scheduled soonest comes first. You never have to organize anything — open the app and the most important thing is already waiting at the top. SEE YOUR DAY AT A GLANCE Switch to Timeline view to see everything grouped into Overdue, Today, Tomorrow, This Week, and Later — a clear shape for your day without lifting a finger. REMINDERS THAT ACT, NOT JUST ALERT When something comes due, BrainBuffer lets you know — and you can snooze it an hour, push it to tomorrow, or mark it done right from the notification. No need to even open the app. ALWAYS ON YOUR HOME SCREEN Add the BrainBuffer widget to see your latest thoughts without unlocking your phone. STAYS WITH YOU Turn on iCloud Sync and your buffer follows you across every device signed into your iCloud account. Prefer to keep everything local? Turn it off anytime — your data, your call. MADE TO GET OUT OF YOUR WAY Pick your accent color, choose light or dark mode, and switch between List and Timeline views — BrainBuffer adapts to you, not the other way around. BrainBuffer isn't trying to be a project manager or a life-organization system. It's the fastest possible path from "I need to remember this" to "it's handled." Empty your brain. Trust the buffer.
