A physique coach running everything through a Google Sheet. We put the app on top of it: his plan lands on the client's phone, and their weight, sleep, steps, biofeedback, training and weekly check-in photos go back into his sheet on their own.

The sheet worked for the coach and nobody else. Clients were sent tabs they could not read on a phone and asked to type numbers back into cells.

Everything useful arrived late and in pieces: a weight in WhatsApp, a photo in an email, a training note that never came at all.

He did not want to abandon the sheet. It is how he thinks, and his whole process lives in it.

Progress photos are sensitive. They needed handling properly rather than sitting in a shared folder.

Ourapproach.

The app reads and writes his existing sheet, so the coach carries on working the way he always has while clients get something built for a phone.

Clients log weight, sleep, steps, biofeedback and their training as they go, and it lands back in the sheet without anybody copying anything.

Weekly check-ins with private progress photos, stored properly, with consent handled and deletion available in the app.

Wearable data comes in automatically where the client has it, so the numbers are not another daily chore.

Messaging and notifications built in, so the coaching conversation is attached to the data instead of scattered across three apps.

Installs to the home screen and is hosted in the UK, with the client owning the code and the data outright.

Built fora phone first.

Light and dark, installed to the home screen. The rest sits behind a client login, so what is shown here is the front door rather than anybody's check-in photos.
