Possible disadvantages

  • Limited Features
    Compared to more comprehensive analytics platforms like Google Analytics, Fathom Analytics offers fewer features, which might not meet the needs of users who require in-depth analysis.
  • Customization
    There are fewer customization options available for reports and dashboards, limiting the ability to tailor the platform to specific business needs.
  • Integration
    Fathom Analytics lacks extensive integration capabilities, which can be a drawback for users who rely on seamless integration with a wide variety of tools.
  • Market Penetration
    Being a relatively newer and smaller player in the web analytics market, Fathom Analytics has less brand recognition and fewer community resources compared to giants like Google Analytics.
  • 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

  • Coach on the same session
    The coach can log the client's session from their own phone or tablet while the client trains
  • Program builder
    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
  • Check-ins and messages
    Recurring check-ins the client fills in, and one-to-one chat with the coach
  • Platforms and languages
    Computer, tablet and phone browser, nothing to install. English and Italian, light and dark

Questions & Answers

As answered by people managing Fathom Analytics 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.

  • Google Analytics Alternatives: Umami vs Plausible vs Fathom in 2026
    Fathom is the most "premium" option. No self-hosted version β€” it's a paid product, and they lean into that. The upside is it just works, with excellent uptime and performance. - Source: dev.to / 6 months ago
