ABOUT US

Built for athletes who take everything seriously.

Opening

Stack Performance exists because no app took serious athletes seriously. 

Most fitness apps are built for casual users, people tracking a morning jog or counting calories loosely. They do one thing reasonably well and ignore everything else. For athletes who treat their performance like a discipline, that's not good enough.

 The problem we solved

Serious athletes were managing their protocols across four or five different apps, a spreadsheet, and their memory. Workouts in one place. Nutrition in another. Compounds logged in Notes. Bloodwork saved as PDFs in a folder somewhere. No visibility across any of it. 

We built Stack Performance to fix that. 

What Stack Performance is

Stack Performance is the only app that tracks the full picture, your training, your nutrition, your compounds and peptides, your bloodwork, your recovery, and your body metrics, all in one place, with an AI coach that has full context of everything you've logged. 

The compound and peptide tracker is the feature we're most proud of. It's the first of its kind in a consumer app. A full library with half-life data, dose logging, and calendar visualisation built for athletes who run a protocol and need to track it properly. 

Our values

Serious — Stack Performance is built for athletes who treat performance like a discipline, not a hobby. 

Honest — we don't sell your data, we don't show you ads, and we don't give you generic advice. Everything in the app is built around you.

 Private — your health data is yours. We store it securely, we never share it, and you can delete it any time.

Closing statement

Stack Performance is built by athletes, for athletes. We're obsessed with getting this right.
