Research.

Five questions about the competition

The next step after discovery was a close look at the apps trainers already use with their clients. I wanted five things answered before a single screen was drawn: who the top competitors are, what features their apps contain, how they gamify, how they market themselves, and how they make money.

I had Claude run the research from a written brief at its highest reasoning setting, reading each platform's own website, pricing page, help centre and store listings on one day, with every claim recorded against the page it came from. The result is a report in the RepGarden repository, fourteen platforms long. The names are in the report. What matters here is the shape of the market, because that shape decides what RepGarden has to include and what it is free to do differently.

What fourteen apps have in common

Fourteen noteworthy apps serve personal trainers and their clients, including the one Benji uses now. Nearly all of them work the same way.

	What the market does
Who pays	The trainer. On eleven of the fourteen the trainer subscribes and the client is invited in; a client cannot find these apps on their own.
What the trainer uses	A website. On it they manage their clients, set programmes and workouts, and can upload their own exercise videos.
What the client uses	A mobile app with a calendar of what to do each week. They watch the videos and log their progress. Five of the fourteen let a client film a set and send it to the trainer.
Reminders	A push notification when a workout is due is standard.
Chat	Every one of the fourteen has built-in messaging.
How they charge	A monthly subscription paid by the trainer that rises with the number of clients, from about $9 to $700 a month across the set. The client pays nothing.
How they get trainers in	A free trial of 14 or 30 days, on all but one. One also has a free tier for a handful of clients.
Gamification	Three of the fourteen have anything you could call a game layer, and it is built from habit checklists, leaderboards, streaks and badges. None has levels, a character, or a world that grows.

The website sells to trainers

Every competitor has a website, and that website sells to trainers, not to people who go to the gym. That matters more than it sounds. The trainer is the customer; the client is a guest who arrives by invitation and pays nothing. So the marketing effort, the free trial, the referral schemes and the paid ads all point at trainers, and the client app only has to be good enough that the invited client keeps using it.

For RepGarden it settles where the effort goes. The website's job is to make a trainer want to move their clients onto it. The app store listing exists to get approved and to be the thing an invited client taps.

Two gaps

The first gap showed up in the app Benji pays for now. It can take a video of a set, and he never uses the feature. Five of the fourteen let a client film a set and send it, and on every one the trainer's reply is a comment under the clip. None has a way for the trainer to pin a note to the second where the knee caves in, step through the video, or mark the moment they mean. The upload is not the feature. The reply is, and nobody has it.

The second gap is gamification. The whole market's idea of a game is a scoreboard: a number that goes up, a list that ranks you, a chain you must not break. Three platforms have built that properly; the rest have one mechanic sitting unused or nothing at all. Nothing in the market has a character, a place, or anything that grows and can be tended. That is where RepGarden's garden goes, and it gets its own entry.

What this changes for RepGarden

• The shape every trainer already knows holds: a website for the trainer, an app for the client, and clients who arrive by invitation.
• The reply to a client's video is the feature, not the upload. It has to land on a moment in the clip, because that is the one thing nobody has.
• The game layer has no one to copy, which is the best news in the report.
