What you pay

Your price stays flat as you grow. Theirs climbs.

Trainerize, TrueCoach, Everfit and Hevy Coach all charge more as your client list grows. Corner is $49 a month whether you coach four clients or four hundred.

At 25 active clients, Corner is the lowest price of the five. From 21 active clients up, none of the four publishes a price as low as Corner's, and the gap never narrows.

Each line is the tier table on that competitor's own pricing page, read October 5, 2026: TrueCoach 3 steps, Trainerize 9 steps, Everfit 13 steps, Hevy Coach 9 steps. Their cheapest published rate is used, billed annually where they offer it, against Corner's monthly price, so every gap shown is a floor.

The basics are here too: a program builder with templates, messages with files, a rest timer, and coaching from your phone. Corner has no add-ons. Everything it does is in the one price.

What it does

Nutrition your clients will not outgrow.

Ninety-two nutrients, every one with a target from the National Academies' tables and an explanation you can read in the app. On Android and iPhone a food is logged by scanning its barcode, and on any phone or computer by searching Open Food Facts and USDA.

Live in the app today: the nutrient panel, its targets and where each number came from.

A logger that knows what they lifted last time.

Every set opens with the last time they did it and an estimated one-rep max beside it. A rest timer between sets.

Live in the app today, in the client's set logger.

A client side good enough to win you clients.

Your client's app is the same depth as yours, not a stripped companion. The weekly check-in arrives already filled in from what they logged.

The client's app is the coach's rooms, on their phone and their computer.

Every change to the plan, on the record.

Every change to a program is kept, with who made it and when, and one tap undoes it. The roster, the week, the check-ins, the messages and the builder are the same rooms on a phone as on a desk.

Live in the app today, on the desk and on the phone.

One price, and the two either side of it.

Questions

What happens when my trial ends?

With three active clients or fewer, you move to Free: the core features stay on and every client you already have stays readable, and your card is not charged. With more than three, you move to Coach on the card you added, at your price. Cancel online any time before day fifteen and you are never charged.

Will my price go up as I add clients?

No. Corner is $49 a month whether you coach four clients or four hundred. Going from twenty clients to forty on TrueCoach costs $948 more a year. That is $57.99 to $136.99 a month, both billed annually, read from their pricing page on October 5, 2026.

I use another coaching app now. Do I have to switch everything at once?

No. Run Corner beside what you use now for fourteen days, with every Coach feature on.

Can I take my data with me?

Yes. Any day, on any plan, one export from your account takes out everything in it — your roster, your templates and notes, your conversations and their files. Each of your clients takes their own diary, program and photos from theirs, without asking you. And you can delete your account from the same place: it is gone from the app at once and purged within 30 days.

Is there an app to download?

Yes. Open Corner in your phone's browser and add it to your home screen: it opens full screen, like any app, on iPhone and Android. Your clients do the same.

Do you take a cut of my coaching revenue?

No. Corner charges a flat price for the software, never a share of your business.

Coach your whole roster in one app, at one price.

Fourteen days free with every Coach feature, and nothing charged today. After that you pay only if you coach more than three clients; at three or fewer you move to Free.
