Possible disadvantages

  • Cost
    FastMail is a paid service, which might deter some users who are accustomed to free email services like Gmail or Yahoo.
  • Limited Free Tier
    Unlike some competitors, FastMail does not offer a free tier, meaning users have to commit financially from the get-go.
  • No E2E Encryption
    FastMail does not provide end-to-end encryption by default, which may be a drawback for users seeking maximum security for their communications.
  • Complex Interface for Beginners
    While feature-rich, the interface may be overwhelming for users who are not technically inclined or are new to email management.
  • Limited Integration
    FastMail may not integrate as smoothly with some third-party services and applications when compared to giants like Google Workspace or Microsoft Office 365.
  • Session brief
    One page before each session: last session, pain, messages and today's plan next to last time
  • Progression proposals
    Load increases calculated from the logged sets, with their reasons. Nothing changes until the coach approves
  • Pain reports
    Clients report pain during a session. No increase is proposed on that exercise until the coach has read it

    The coach can log the client's session from their own phone or tablet while the client trains

    Weeks, days, sets, reps, load, RIR and rest, with supersets and circuits. Published versions stay unchanged
  • Import from Excel or CSV
    Programs and clients come in from an .xlsx file, a CSV or a paste
  • Goals
    A target on a lift with a date, and whether the client is ahead of pace
  • Calendar
    Day, week, month and agenda views. Clients can request a session and the coach confirms it

Questions & Answers

As answered by people managing FastMail 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.
