Personal Trainer Session Pack Tracker with Late Cancel Rule and Session

Personal Trainer Session Pack Tracker is an offline app (one HTML file in a zip). You sell a pack (for example twelve one to one sessions valid for twelve weeks), then book each session with a date and time. A session that is done, a late cancel or a no-show uses a session according to the rule you set. The app shows sessions used, booked ahead and left.

The problem it removes: A client buys twelve sessions and months later neither of you can say how many remain. Late cancellations are argued about, a pack runs past its end date, and a client with sessions left has nothing booked and drifts away. This app keeps the count and the diary together so the answer is one glance.

What is inside:

• Packs with sessions, price, amount paid, start date and weeks of validity, with the last valid day worked out
• Session diary with Booked, Done, Cancelled in time, Late cancel and No-show; the app refuses a session beyond the pack, after the last day or at the same time as another
• Two settings for your policy: whether a late cancel and a no-show use up a session
• Today page with one tap Done, Late cancel and No-show, and a month calendar of sessions
• Pack balance: used, booked ahead, left and still available to book, with status Active, Low, Expiring soon, Expired or Used up
• Income earned so far at the per session rate, money still to give on live packs, and a WhatsApp list of clients with nothing booked ahead
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: independent personal trainers, small fitness studios and yoga or pilates teachers in the UAE who sell packs of sessions and track them in a notebook or in chat messages.

What it is NOT: It does not set programmes, record health information or measurements, take payments, send messages by itself or issue tax invoices. Earned income is a simple share of the pack price per session, not an accounting treatment: ask your accountant how to record prepaid packs. Pair and group packs are one pack per paying client. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.
