FairSub

Coach Meister is one of the most actively developed substitution apps for youth soccer coaches in 2026. Built by Eloy Bruckhoff (the developer behind the older SubNow app), it added a Live Activity, an Apple Watch companion, and a polished Report Engine in just a few months. If you have been comparing it to FairSub, you have noticed the overlap — both apps are built to make matchday substitutions easier and fairer.

This comparison is written by the FairSub team, so read it with that context. Coach Meister is a serious product and we will be direct about where it is better than we are, because the trade-offs are worth understanding.

Quick recommendation

Choose Coach Meister if you want an Apple Watch app today, you coach a single team and value setup speed above everything else, you want a per-match shareable report PNG with rich event tracking, or you find the idea of one app for everything (substitutions, score, tactical notes) appealing.

Choose FairSub if you want a substitution engine that recalculates when reality diverges from the plan, you coach in a language other than English, you care about minimal data on your players' families, or you want to plan multiple upcoming matches rather than just today's.

What both apps do well

Both apps cover the basics competently. Both:

• Generate a substitution plan automatically, so you do not have to do the math on a clipboard
• Track playing time per player across periods or halves
• Handle goalkeeper time separately
• Send notifications before substitutions are due
• Show match data on the iOS lock screen via Live Activity
• Work offline at the field

If you simply want every player to get minutes, either app can do the job.

Where they differ in substance

The engine — fixed intervals vs forward simulation

This is the most important difference, and Coach Meister's own product shows it clearly.

Coach Meister uses fixed rotation intervals. You set a sub interval (every 5, 10, or 15 minutes), and the app generates a substitution plan as a static list of timestamps. In its Plan View, every substitution is plotted in advance: 01:15, 02:30, 03:45, 05:00, 06:15, 07:30, 08:45. If a substitution gets skipped — because the ball was in play, because a player asked to stay on, because you simply missed it — the plan does not recalculate. The skipped substitution is logged as an "Out of Schedule Sub" with a reason code (Routine, Puffed Out, Minor Injury, Motivation), and the rest of the schedule ticks forward unchanged.

The result, in Coach Meister's own example report on their website, looks like this: "Uneven and short on minutes / GAP 02:07 / Bill 00:00." That is from their own demo. A fixed-interval engine can be set up in two minutes, but it cannot guarantee an even distribution when matches do not go to plan — and matches never go to plan.

FairSub uses what we call forward simulation. At every moment, the app projects the rest of the match and balances the projected end-of-match minutes for every player. When you skip a substitution, the engine recalculates from where you actually are. When a player gets injured and goes off, the engine reshuffles future subs to bring everyone closer to the same final number. The plan is not a static list of timestamps; it is a live projection that updates after every whistle.

We have run 50 simulated full matches through this engine across injury scenarios, goalkeeper rotations, late arrivals, and early exits. 490 unit tests cover the edge cases. More on how the engine works.

Live Activity — passive vs interactive

Both apps have a Live Activity. The difference is what you can do with it.

Coach Meister's Live Activity shows the match time and the next substitution on the lock screen. To act on a sub, you unlock the phone, open the app, and tap the confirmation. The Live Activity is informational.

FairSub's Live Activity is interactive via iOS App Intents. From the lock screen, without unlocking the phone, you can pause the clock, resume play, end the current period, or confirm the next substitution. The phone stays in your pocket for the whole match, and the substitution gets confirmed by a single tap on the lock screen.

One minute before a sub, FairSub also plays a whistle through APNs push, which means the sound and screen wake-up happen even if the phone has been asleep. No banner notification — just the whistle. The Apple Watch is great, but you do not need a Watch to coach hands-free with FairSub.

Player data — what your app needs to know about parents

This one is a deliberate design choice on both sides, and we believe it matters for European coaches especially.

Coach Meister's player profile collects: name, number, photo, notes, and contact details (contact name, phone number, and email). For European coaches, that matters. A child's photo, a parent's email address, and free-text notes about a player are personal data. Collecting that data can create consent, storage, and purpose-limitation questions that many volunteer coaches do not expect to manage.

FairSub asks for one thing per player: a name. Optional positions if you want the engine to consider them. No photos, no parent contacts, no free-text notes. Communication with parents happens in WhatsApp or your team's preferred channel, not in FairSub. We wrote about this design choice in what a youth soccer app really needs to know about your players.

This is less a criticism of Coach Meister than a product-philosophy difference. Coach Meister treats the rich player profile as a feature. FairSub keeps player data deliberately minimal so coaches do not collect more family information than the app actually needs.

Languages

Coach Meister is English-only. FairSub is available in English, Swedish, German, Spanish, French, Norwegian, Danish, European Portuguese, and Italian — with terminology checked against each federation's official vocabulary. If you coach in Germany and want to call kick-off Anstoß instead of "kick-off", that matters.

Multi-match planning

Coach Meister handles one match at a time. There is no "upcoming matches" concept — the team's format is the match's format. When you finish today's match, you set up tomorrow's by editing the same shared configuration.

FairSub treats each match as a separate object with its own opponent name, date, squad, formation, period count, and rotation style. You can plan three matches in advance, see the upcoming list, and edit the lineup for any of them without affecting the others. For coaches who plan a few weeks ahead, this matters.

Squad selection rate — who gets picked?

Coach Meister tracks playing time within a match but does not surface a season-level signal for whether every child is being selected fairly across matches. A coach who calls up the same nine players every weekend, and distributes minutes evenly within each match, can still be quietly unfair to the children who keep getting left out.

FairSub shows a green/yellow/red dot next to every player based on how often they have been selected across the season. It is a small thing, but it changes which child you remember to text on Friday evening. More on fair squad selection.

Where Coach Meister is genuinely better

Three things, honestly:

Apple Watch. Coach Meister has a native Apple Watch app — run subs entirely from your wrist, with timer pause/play and auto-rotation. FairSub does not have a Watch app yet (it is on the roadmap for late 2026). If you coach on rainy fields and value at-a-glance feedback, Coach Meister wins on this dimension today.

The matchday share PNG. Coach Meister's Report Engine generates a polished, branded image you can save to Camera Roll and share with parents or club admins after a match. The image has a small "subs managed with Coach Meister" footer, which is honestly clever marketing. FairSub's equivalent is the monthly report — a different format covering a longer time window — and we deliberately do not generate a per-match PNG. That reflects a different belief about what coaches should share with parents after a match.

Setup speed. Coach Meister markets "under 2 minutes" from download to first match, and they hit that target. FairSub asks you to name your players upfront, which adds a few minutes but means the engine knows who is who from day one.

Side-by-side feature comparison

Pricing

FairSub's Coach licence is $14.99/year with a fully functional free tier. The free tier includes unlimited matches, full match history, the smart engine, basic alerts, and dark mode. The paid licence unlocks position-aware substitutions, the monthly report, sound alerts, and other quality-of-life features.

Coach Meister is $2.99/month (no annual plan), which works out to $35.88/year — roughly 2.4× FairSub's annual price. Free tier limits you to one team and locks the entire match history behind Pro, which means a new user cannot save the data from their first matches without paying. That is a more restrictive free tier than FairSub's and pushes the subscription decision earlier in the coach's trial experience.

Two product philosophies

Coach Meister optimises for getting started fast and showing parents what happened today. The PNG report after a match is a real marketing strength because it is made to be shared. The implicit trade-off is that the coach's role expands toward broadcasting: every match becomes a deliverable that gets shared, every weekend.

The coach's role is already visible. Every parent watches. Every player questions why they were taken off. Every matchday is a review. We do not think broadcasting that role in real time makes coaching easier — we think it makes it harder. FairSub is designed for the coach: phone in your pocket, engine recalculating when reality changes, eyes on the players. Parents get a summary at the end of the month, not a play-by-play after each match. Per-minute scrutiny pushes coaches toward second-by-second fairness when the real fairness work happens over a season.

Neither approach is wrong. If you read this list and Coach Meister's strengths matter more to you, download Coach Meister. If FairSub's strengths matter more, try FairSub. The free tier covers a full team with no time limits, so you can find out within one match whether the engine and the lock-screen workflow click for you.
