Questions & Answers

As answered by people managing Udemy and Coachstack.

Which are the primary technologies used for building your product?

Coachstack's answer:

Next.js and React with TypeScript, Supabase (PostgreSQL with row-level security), Tailwind CSS, hosted on Vercel.

What makes your product unique?

Coachstack's answer:

Coachstack is built around the decision a coach makes before each session. One page shows how the last session went: sets done, pain reported, messages waiting, and the session planned for today next to what the client lifted last time. Load increases are calculated from the logged sets and arrive as proposals with their reasons; nothing changes the programme until the coach approves. If a client reports pain on an exercise, no increase is proposed on it until the coach has read the report.

Why should a person choose your product over its competitors?

Coachstack's answer:

Because it keeps the training record and the coaching decision in one place. Clients log every set from the phone's browser, with nothing to install, and the logger keeps working without signal. The coach can log on the same session from their own phone or tablet. Programmes and clients come in from Excel or CSV, so there is no starting from zero. It is free during the beta, in English and Italian.

How would you describe the primary audience of your product?

Coachstack's answer:

Personal trainers who coach both in person and online: independent coaches and small studios run by one coach, with clients who train in the gym with them and on their own between sessions.

What's the story behind your product?

Coachstack's answer:

Many personal trainers still run their business on spreadsheets, paper notes and chat messages: the programme lives in one file, the client's sets in another, and the reason a load was changed lives nowhere. Coachstack was built in Italy to put those pieces together, so that every session is recorded once and the next one starts from what happened in the last.
