FAQs

Spotter. Every platform in this category gives you somewhere to put a plan; Marginal Improvements will write it. Ask for a four day upper/lower split, an intake form, or a list of who has gone quiet this week, and it does the work and shows it to you before anything reaches a client.

No. Spotter drafts and proposes, and you approve. It will tell you it has written a split and show you the split, and nothing lands on a client’s plan until you say so. That is deliberate and it is not a setting.

An iPhone app with their plan, their habits and their next session with you in it. It is the only client app, so a client on Android uses the web for now. Everything they log comes straight back to their profile in Marginal Improvements.

Yes, through Stripe, and the money goes to your own Stripe account rather than through us. Clients can pay for a session when they book it, buy a package, or subscribe, and the payouts are yours.

No. There are 5,000+ exercises and recipes to pull from, and you can import a starter library rather than beginning with an empty screen. Anything you build on top of it is yours and reusable across every client.

How many clients you can carry, and nothing else. Every plan including the free one has the whole product, so you move up when you grow rather than because a feature was being held back.

Yes, and you should expect to spend an afternoon on it rather than a minute. Client details and measurements import cleanly; plans built in another tool’s format usually need rebuilding, which is the honest answer and the reason the library is worth setting up first.

On everything your clients see. Your public page lives at your own link in your own colours, and Marginal Improvements can suggest a theme from a photo of your existing branding rather than making you pick hex codes.
