There was no grand vision. No market research report. No TAM calculation.
It started with a conversation with my fiancée.
She's a yoga instructor. She has students she genuinely cares about — people who show up twice a week, whose progress she tracks, whose payments she remembers, whose birthdays she knows. She runs a real practice. A small one, but real.
And she was managing the whole thing on WhatsApp.
Not because she didn't know better. She told me herself — there are apps for this. Apps that track attendance, manage payments, send reminders. She knew they existed.
She just found it easier to open a WhatsApp chat, type a name and a date, and move on.
I sat with that for a moment. Here is someone smart, organised, genuinely good at her work — and the best tool she had found for managing her clients was a messaging app not designed for any of this. A thread of names and dates that she had to mentally parse every time she wanted to know who had attended last Tuesday or who still owed her for the month.
I told her I was going to build something better.
Before writing a single line of code, I did what I should have done — I asked questions. Not just to her, but to her friends. Other yoga instructors, fitness coaches, tutors. I wanted to know what they were actually using.
The answers were the same everywhere.
A paper register. A WhatsApp group. Phone notes. Sometimes a copy of Excel with columns that had drifted into chaos. One person was using a physical notebook she carried to every session and updated by hand.
Nobody was using a proper app. Not because they didn't want one — but because every app they had found was either built for gyms with staff and membership systems, or for agencies billing corporate clients. Nothing was built for one person managing thirty students out of their own home or studio.
That is the gap. One person. Thirty clients. No admin staff. No time to learn complex software. Just someone who wants to do the work they love and not spend their evenings on WhatsApp trying to remember who attended last week.
I decided to build it from scratch. No templates, no open source base — built from the ground up because I wanted to get every detail right for this specific person: the solo professional who is good at what they do and just needs the admin to stay out of the way.
The app would track clients, attendance, payments. It would be free. It would work on Android and the web. And it would have an AI assistant — not a chatbot bolted on for the sake of it, but something genuinely useful. Something you could just talk to. "Mark Amrita attended today." Done. No tapping through menus.
I called it UFCM. Universal Freelance Client Manager. Not the catchiest name, but it described exactly what I was building. That changed later.
The app is called Prabzo now. It has been live on the Play Store since May 3rd. 250+ users across 15+ countries found it without a single rupee spent on advertising.
I built it for my fiancée. Turns out a lot of people needed it.
If you are a yoga teacher, tutor, fitness coach, therapist, or any kind of solo professional managing clients on WhatsApp or Excel — Prabzo was built for you.
