Features and specs

What each product offers, as listed by its team.

InboxZero 4 features
Coachstack 11 features
  • Increased Productivity
    InboxZero encourages immediate action on new emails, leading to a more organized workflow and preventing accumulation of unread messages, which can boost productivity.
  • Reduced Stress
    Keeping an empty inbox reduces the overwhelming feeling that can come from seeing a large number of unread emails, which can help decrease stress and anxiety.
  • Improved Focus
    By handling emails as they arrive or scheduling set times to process them, individuals can dedicate more focused attention to other tasks without the distraction of a cluttered inbox.
  • Better Email Management
    Regularly organizing and archiving emails keeps the inbox tidy and ensures important messages are not lost among less urgent ones.

Possible disadvantages

  • Time-Consuming
    Maintaining an empty inbox requires constant attention and can be time-consuming, especially for those receiving a large number of emails daily.
  • Potential for Decreased Efficiency
    Focusing too much on achieving InboxZero can lead to spending unnecessary time on less important emails, detracting from more critical tasks.
  • Pressure and Anxiety
    The need to maintain an empty inbox can add pressure and anxiety, particularly if it's deemed unmanageable due to external factors such as the volume of incoming emails.
  • Negative Impact on Work-Life Balance
    The requirement to continuously check and manage emails to maintain InboxZero can lead to work encroaching into personal time, potentially impacting work-life balance.
  • 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
  • Offline workout logging

  • Coach on the same session

  • 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

Questions & Answers

As answered by people managing InboxZero 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.
