Naptar helps personal trainers keep members, appointments, session credits and payments in one place instead of notebooks and spreadsheets. Members join a trainer’s hub with an invite code and request sessions from the trainer’s weekly availability. It grew out of my twin’s real needs at their gym, and I run it solo end-to-end: product, design and full-stack development. The name comes from “naptár”, Hungarian for calendar, and it happens to contain “PT”.
