Your free month

It fits, because somebody makes it fit.

Tell us how you run things. We build the rest.

  • First

    Start the free month

    Your email and your business name. That is the whole signup. 1 month free. No card.

  • Then

    Write to us in the app

    Talk to Anda is a screen in the app, and a real person reads it. Say what is missing, how you colour your calendar, which screens you never use. Several of the screens on this page began as one customer writing to say what she was missing.

    Rather not start with an empty calendar? Send your client list, a spreadsheet, or a photo of your paper diary to contact@tendmatehq.com, and we set it up for you before you log in. Included in the price.

  • By the end

    An app that fits your business

    What you ask for gets built, free, and it arrives for everyone. Your job types, your colours, only the screens you use. $9 a month after, you and up to four helpers included.

One price. That is the whole pricing page.

Already in another app, or in a spreadsheet?

Send it to us as it is: an export, the sheet, or a photo of your diary. We bring your clients, how often each one is due, your prices and your history across before you log in. It is free, and your old app keeps working while you decide.

Before you start

Questions people ask

Does it text or email my clients?

Not yet, and if you want it, ask: a feature a customer asks for gets built, and it is free. Emails to your clients would cost you nothing. Text messages would be a small package, because the SMS providers charge for every message sent, not us. Today TendMate keeps the schedule and the records, and you message your clients the way you already do. For somebody who asked for a price it keeps the message you sent and what they replied.

Can my clients book online?

Not yet. Your work is the same clients coming round again and again, so the calendar fills itself in from how often each one is due, and a new enquiry is written down as a lead with the day to come back to them. If your clients want to book themselves, say so: a calendar you share with your free days, where a client picks one, is the kind of thing we build for the person who asks, at no extra cost. We will work out together what suits your business best.

What does a helper see?

The schedule, the addresses and the notes for the work she is sent to, on her own phone. Not your prices, your expenses or your totals. You choose, screen by screen, what each helper can open.

What if I have more than four helpers?

Contact us. Extra seats are $1 a month each, and we add them for you. Tell us how you run them too: if you want them in teams, or there is something that would make managing them easier, that is exactly the kind of thing we build for you, free.

Does it work without signal?

Yes. Everything you need is on the phone already, and it catches up when you are back in range.

I already have a spreadsheet, or another app. What happens to it?

Send it to us: a spreadsheet, a CSV, an export from another app, or a photo of your paper diary. We bring your clients, your schedule and your history across before you log in, and that is included in the price.

What happens after the free month?

$9 a month, flat, for you and up to four helpers. No card is taken during the month, so nothing is charged unless you choose to carry on. Cancel any time and export everything, clients, visits and history, in one click.

Your clients are in a notes app, a calendar and a spreadsheet.

Not because you like it. Because training software is built for the gym with a front desk and a membership system, and the price and the setup assume one. With a mat, a kettlebell and a car, the choice is a spreadsheet you maintain by hand or a platform meant for somebody else's business.

So the client who trains twice a week is in the calendar because you put her there, and the one who went quiet in March is noticed when you happen to think of her. That is the whole problem we are solving.

Today, and after

Why most client lists fall apart

  • The next date

    On the spreadsheet

    Nearly every list we have seen has the same flaw: it holds the next session. That works until one client goes on holiday, one drops from twice a week to once, and one pauses for a month with a bad knee. Now every date after that is wrong, and the only way to fix it is to rebuild the calendar by hand.

    In TendMate

    The fix is small and it changes everything: record the last session, not the next one. The last session is a fact — it either happened or it did not. The next one is arithmetic:

    Next due = Last session + Frequency (in days)

    Once a week = 7 · Every 3 days (about twice a week) = 3 · Every 2 weeks = 14 · Only when booked = no interval

    Move a session, skip a week, change one client to once a week for the summer — you only ever update one thing, and every date after it corrects itself. That is the whole trick, and it is what TendMate is built around.

What you get

  • Your week fills itself in

    Say how often each client trains and their sessions place themselves on the calendar. Move one to another day and it stays moved.

  • Nobody goes quiet unnoticed

    Overdue and due-soon are surfaced before they bite, and the window is tuned to how often each client trains — so a weekly client is not permanently flagged as due, and a client who has not been in for three weeks is.

  • Paid in parts, tracked on the session

    Half up front and the rest next month — each session carries its price and what has been paid so far, so the balance is on the card and not in your head.

  • You and your other coach, flat

    $9/month covers you and up to four helpers. More helpers are $1 a month each. No cap on clients or sessions. A coach covering for you sees the day — the client, the goal, the last workout — and not your rates or your totals.

  • Your data stays yours

    Export everything — clients, sessions, history — in one click, any time. No contract, cancel whenever, and take your data with you.

Built for you if…

  • You train the same clients on a repeating schedule and you are tired of working out who is due.
  • You take payment in parts and want to see who still owes without adding it up.
  • You have a second coach covering some sessions and need to share the day without sharing your rates.
  • You run the business from your phone between sessions, and the calendar should not need a laptop.
  • You want something genuinely simple — not “simple” with forty settings.
