Putting an installable client app on top of a coach’s Google Sheet — synced automatically.
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.
Where friction was costing momentum before the rebuild.
Rigid SaaS coaching apps broke the coach’s trusted spreadsheet logic
Generic platforms could not replicate the coach’s nuanced biofeedback ratios and tracking calculations already perfected in Google Sheets.
Poor mobile UX for daily weigh-ins and check-in photos
Editing spreadsheet rows on a phone screen caused missed client check-ins and scattered photo links.
What we changed, engineered, and shipped cleanly.
App UI on the front, Google Sheets intact underneath
Designed a native-grade mobile interface reading training & nutrition plans from the Sheet while pushing clean check-ins back automatically.
Wearable metrics & photo check-in automation
Synced sleep, steps, body weight, biofeedback, training logs, and weekly progress photos straight into structured columns.
Built for desktop clarity and thumb-first mobile conversion.

Skulpt
A triathlon coach writing swim, bike, run, brick and strength sessions in a spreadsheet, and athletes trying to train off it on their phones at six in the morning. We built the app instead: the coach writes the block, the athlete opens their phone and sees today's session, the numbers to hit and what to eat.

Team Tonk
Jimmy Tonkinson is an IFBB Pro in Classic Physique who coaches online as Team Tonk. Every new client came through word of mouth: a basic enquiry form, then a Loom from Jimmy. We built the front door and the clubhouse behind it, a website that sells the coaching and takes applications, and a client area with Jimmy’s lesson library and the team’s own community. Thirteen days from go-ahead to signed off.

Scheduling, payments and paperwork software for personal trainers, designed and built by us from the database up. It deliberately does not touch the coaching. Programmes, check-ins and nutrition stay in whatever app the trainer already uses, and PT Desk takes the admin that eats their evenings.
