The situation

Independent personal trainers in India run their business from notebooks, spreadsheets and WhatsApp threads. Sessions go uncounted, payments slip and clients drift away without anyone noticing. They needed one tool built for how they actually work: on the phone, between sessions.

What we did

A session in one tap.

Punch cards show each client's progress at a glance, and logging a session takes one tap.

See who's slipping.

Overdue and lapsed clients show up on their own, so trainers can follow up before they're lost.
