Senior coaches · regional to National 2 · Free
The match call-up, the training register, how players felt after the session: three small tools for the coach. Every player answers with one tap from his own space, and you see straight away who is missing. Nobody left to chase. You keep your WhatsApp group for everything else.
Free, no card required · no time limit · no sensors to fit
One tap for the player, the count for you: “11 available out of 14, 2 absent, 1 no reply”, with the names. And the day you want to go further, the team sheet and the Virtual Staff are already there.
The three tools · free
Who is available on Saturday, who came to training, how they felt: the three questions every coach asks every week, and that get lost in a WhatsApp thread. Here, every player answers with one tap, and you see straight away who is missing.

How they felt after the session
And how are your players notified?
The call-up and the post-session question arrive in each player's MyMister space, with a notification in the app. The Android app is coming to Google Play; on iPhone, MyMister opens in the browser. Keep your WhatsApp group: post the link there, your players answer with one tap, and you no longer count anything yourself.
To get started: you create your account, add your players with their email address, they receive an invitation and create their account in two minutes. Your match schedule, we enter it for you.
What the coach's week looks like
Depending on the club, the staff is a head coach and one assistant, or a handful more. Either way, a good part of the week goes on the same thing: asking, chasing, counting.
Monday
A poll in the WhatsApp group, thumbs up, a few “not sure yet”, and answers buried between two videos.
Friday
Chasing them one by one, counting by hand, and settling the squad the night before the match hoping nobody was forgotten.
Tuesday night
The register in a notebook, or nowhere. The player drifting away, you notice too late. The one who says “I'm fine” and gets injured on Saturday, too.
Whether you are on your own, or with an assistant or an S&C coach
MyMister replaces nobody. It takes what costs you time without teaching you anything: asking, chasing, counting, copying out. You keep the pitch, the team selection and the decision. It documents, you decide.
How they felt after the session
Everybody knows RPE. Almost nobody sustains it across a season, because collection rests on paper, WhatsApp chasing and re-keying — after a month, half the squad has stopped answering. Here, the question goes out to every player on its own, and the staff has nobody to chase.

Nobody predicts an injury, and neither do we. What the tool can do: spot a player drifting outside his usual range and tell you while you can still act on it. Who plays and who rests is decided by the staff.
What the staff gets every week
GDPR & data ownership
How players felt, their load and the response rate are free, with no time limit. Start with call-ups: the post-session question follows naturally once your players have the habit.
Going further · also free
Once your players are used to answering, MyMister also keeps the memory of your matches: the team sheet read automatically, a performance index per player, load for physical risk, and a Virtual Staff that answers about your players in plain words. Enough to arm the four decisions that come round every weekend.
Pick the side
Who is in form, who is playing on, who needs a rest on Saturday.
Protect the squad
RPE collected without chasing, cross-referenced with minutes: the players whose load is out of the ordinary, flagged early.
Develop players
Who is improving, who has stalled, and what to say to him about it.
Answer
The player who asks why he is no longer playing: his minutes, his matches, his index.
What it asks of you
Uploading the team sheet, reading it and writing it up all happen without you. What is left is validating the events — and that is it.

Per match. That is all we ask of you.
On the post-session side you have nothing to do: the question goes out to every player on its own. On the match side, validation is the only step that depends on you — and for a match whose events you have not kept in your head, allow for the time to find them again in your notes or in the video.
MyMister does not coach for you. It gathers, reads and formats what your season already produces — so that every decision is taken with the full picture.
Performance · going further
It is calculated from the team sheet alone — line-up, minutes, events that you validate. You will have to defend it in front of a player who disputes it, so here is how it is built.
SFI · Performance
One index per match, accumulated across the season, built on 25 criteria — not just goals and assists. The model reads the strong signals, the decisive events, and the weak signals, everything that never shows up in a stat line. That is what makes a full-back comparable to a striker, and a holding midfielder readable despite an empty stat sheet.
Method
A CIFRE doctorate with the URePSSS laboratory at the University of Lille is working through the 25 criteria that feed the indices. The work is ongoing: we claim no established validation, but the arrangement is formally agreed and the protocol documented.
In practice: one number per player and per match, calculated from the team sheet alone, that you can show the player who disputes it.
The player's side
Every player has his own MyMister space, free. He answers there in a few seconds, and finds what concerns him.
What he does
What he sees, and what he keeps
He gives his consent when he creates his account, and can delete it at any time.
The product, for real
Captures taken inside the application, with names and identifying data removed. Nothing here is reconstructed — we would rather show fewer screens, but real ones.
Coach workspace · on opening
The state of the squad written in plain words, and the three priorities for the week — each with the button that leads to the matching screen. Here, 9 injured out of 27: the tool states the situation and suggests where to start. What you do with it stays with the staff.
← drag to explore the screen →
Squad · mapped by position, and the first eleven
Average SFI line by line — a goalkeeper at 12, a defence at 16, an attack at 14, comparable with each other. Then the eleven suggested for the shape and the intent you choose, with each player's trend: improving, steady, declining. Staff comments are tagged with @ and stay attached to the player.

Virtual Staff
Eleven specialists you call on with @ — strength and conditioning, doctor, analyst, recruiter, youth development, psychologist, nutritionist, goalkeeping coach. They answer about your players, with your data attached. At the foot of the screen, the sentence the tool displays itself: “Decision-support recommendations — the final decision is yours.”

Price
Call-ups, attendance and how players felt should not depend on anyone's budget: that is what gives you time back from the very first week. You create your account, you invite your players, that is it.

No, and this is not a safety rail bolted on afterwards: it is how the product is designed. MyMister states the facts, shows the trends, flags the thresholds crossed and writes up a reading of your squad. There is no “do this” notification anywhere in it. The team, the rotation, the transfer window — that is your signature, not ours.
The call-up and the post-session question arrive in each player's MyMister space, with a notification in the app. The Android app is coming to Google Play; on iPhone, MyMister opens in the browser. There are no text or email reminders: the simplest way is to post the link in your WhatsApp group. You then see who has not answered, and chase only those.
Yes. It stays the place where the squad lives. MyMister only takes what gets lost in it: the answers to call-ups, attendance and how players felt, which you no longer have to count yourself.
They cannot answer a call-up or say in advance whether they are coming. You can, however, take the register for them and enter how they felt in the dressing room. Signing a player up takes two minutes and counts as consent; a player may decline.
No. Call-ups, attendance and how players felt need nothing but a phone. If your club already has GPS, its data can be imported and shown alongside; it is never a prerequisite.
Two distinct regimes, and it is better to know before you start. Analysis of your squad — collective reports, indices, the season's history — stays with the club. Data belonging to each individual player is jointly held by the player and Sfeira: it remains his, the club accesses it within the sporting relationship, and nothing individual is processed without his explicit consent. Under-15s are excluded from the scheme — a legal constraint. And a player's score is never published unless he asks for it.
One minute to call players up, thirty seconds for each training register, nothing for how they felt: the question goes out on its own. And no more chasing by hand.
No catch: it is free, with no card required and no time limit. MyMister is published by Sfeira, which works with sports clubs on other products (ticketing, memberships, supporter app).
Who builds it
You are about to hand us your players' answers, attendance and how they felt. Here is what sits behind the tool, so that you know who you are handing them to.
Research
The 25 criteria that feed the indices are being worked through in a CIFRE doctorate with the URePSSS laboratory. The work is ongoing and the arrangement formally agreed — we will tell you what is established and what is not yet.
Method
Every Virtual Staff specialist draws on a knowledge base built with practitioners: RPE and load monitoring as a foundation that holds at every level, GPS data as an enrichment layer.
Publisher
MyMister is developed by Sfeira, a SaaS publisher serving sports clubs — ticketing, memberships, supporter engagement. One company, a named team, somebody to talk to when it goes wrong.
MyMister is a Sfeira product — sfeira.com
Call-ups, attendance, how they felt: your players answer with one tap, you see who is missing. Free, from next week.
