Session Flow for personal trainers
Session Flow is a scheduling and payments app for professionals who work by appointment. For a personal trainer, that means you add a client once, with the days, the time and the fee, and the schedule fills itself in. One tap marks a session as paid, and the app adds up what is still open, client by client.

Your whole week, booked
- Monday, Wednesday and Friday at 7 am: pick the three days in one go, and the app books the sessions for every week.
- Client missed a session or asked to move it? The no-show is recorded; a reschedule moves the session to the new day, and the app warns you if it clashes with another client.
- Holidays and time off that you mark take the sessions off those days; a client who travels gets a pause of their own.
- The Today screen lists the day's sessions in order, with each client's time and anything still open.
Monthly fee, package or per session
Each client on their own terms: a flat monthly fee, the sum of the month's sessions or a price per session. A prepaid package becomes a balance, and each session draws from it (Premium). A rate increase starts on the date you choose, and anything left open before it keeps the old price.
Reminders and payment messages
The session reminder, with the day and time, comes ready for WhatsApp on every plan; on the Today screen, the bell shows who still needs one. On Premium, the payment message comes ready too, with the open sessions and the total, and you can send them one client after another.
Partner and small-group training
Partner training or a small group is a group: one time slot, and each participant has their own fee, no-shows and payments (Premium).
What it does not do
Session Flow does not build workouts or store fitness assessments: it takes care of the schedule and the payments. PDF receipts and a spreadsheet of payments for your accountant are built in, and the data stays on your phone (the cloud is optional, on Premium).
Questions personal trainers ask
My client trains three times a week and pays monthly. How do I set that up?
Pick the three days at their time and choose monthly billing with a flat fee. The month's sessions show up on their own, and one tap marks the month as paid.
I sell packs of 10 sessions paid up front. Does that work?
Yes. Set the repeat to end after 10 sessions, and the app stops when the pack is used up. On Premium, the prepayment becomes a balance, and each session uses part of it.
I train clients at the gym, at home and online. Is that fine?
Yes. The app does not care where you train: each client has their own time and session length, and online clients can have the video link on their record, sent along with the reminder.
Can I build workouts or programs in the app?
No. Session Flow is your schedule and your payments; workouts stay in the app or spreadsheet you already use.
