Built for the stack.
The private, on-device tracker for peptides, GLP-1s, protein and calories. Two taps to log. Zero spreadsheets. Zero noise.
The stack
If you take it,
Stak logs it.
Stak is a personal log. You add what you take. We never recommend, never coach, never diagnose.
The early access crew
Built with the people
actually on the stack.

Stak is shaped by the early access crew, week by week. Get in now and your feedback ships.
I was tracking three things in three different apps. Stak just put it all in one place and shut up about it.
Early access user, Tirzepatide protocol
Finally a log that does not try to coach me or guilt-trip me. It just remembers what I took.
Early access user, BPC-157 + protein
The vial counter alone is worth it. No more counting clicks at 6am.
Early access user, GLP-1 month 5

Built for the protocol
The things you actually
wake up worrying about.
Two taps to log
Open. Tap. Done. A dose, a shot, a scoop, a meal. Logging is the easy part.
Dose + vial calendar
Know what is coming. Know how many shots are left in the vial. No more math at 6am.
Protein floor
GLP-1s crush your appetite. Stak makes sure you still hit your protein number, every day.
Side-effect log
Two-line notes today turn into useful data the next time you sit down with your clinician.
Weekly recap
Every Sunday, a quiet summary of what you actually took, ate and weighed. Trend, not noise.
Yours to export
CSV or PDF, anytime. Your data lives on your phone and leaves with you when you want it to.

Log in two taps
A dose, a shot, a scoop, a meal. Stak remembers the small details so you do not have to.

Read the recap
Every Sunday, a quiet summary lands. Trend, not noise. Share with your clinician if you want.
The Stak ethos
This is not a wellness app.
This is not a coach.
This is not a doctor.
Stak is a quiet log for the people who already know what they are doing.
