Coach's Diary
Who came, what you did, and what to remember next time.
Four sessions · three turned up · one thing to remember
Attendance and the note take ten seconds between clients. The line you leave for next time is the first thing you see when that client returns.
A trainer with twenty clients carries twenty small histories in their head. Coach’s Diary keeps them on the phone instead: who is booked, who turned up, what was done, and the one thing to remember next time. A message to a client is drafted in the app and sent by whatever you already use. A backup is one file, locked with a passphrase you choose and kept wherever you like. Nothing leaves the phone unless you send it.
What it does
-
The week, then the day
Clients repeat weekly, so the week is set once and Today shows who is next. A moved or cancelled session is the exception and leaves the rest alone. When a session ends, the outcome (turned up, cancelled, no-show) and a one-line note take ten seconds, one hand, standing.
-
The line that waits for next time
Before a session, the client's screen shows what happened last time and the standing things worth knowing, which the app calls Key Context. Above both sits the one line written on the way out last time: the thing to ask, check or bring up. It stays there until it is marked done, so a promise made at the door is not lost by the next morning.
-
Messages without a platform
Templates fill in the client's name and time, then hand the text to whatever messaging app you already use, through the phone's share sheet. Coach's Diary never sends anything itself and keeps no record of what you sent.
Process
- Problem
- A trainer's clients live across the calendar, the messages app, a spreadsheet and memory. What gets lost is what happened last time and the small promise made at the end of it: the question to ask, the change to try, the thing to follow up.
- Current bet
- Put attendance, the note and the next-time line within one tap of the session, and make that line the first thing seen before the next session with the same client. Keep the app off the network entirely, so there is nothing to sign up for and nothing to trust.
- Hard problem
- Ten seconds, one hand, standing, between clients. And a message flow that runs through the trainer's own messaging app instead of replacing it with another inbox.
- Status
- In pilot on iPhone through TestFlight and on Android by direct install, with a small roster of trainers. Progress tracking is drawn but waits on what the pilot says.
