StackMate
Read full descriptionHide full description
Everything you take, in one calm place. StackMate is a thoughtful way to organize your peptides, supplements and medications. Keep your schedule together, log your doses, do the vial math, and get gentle reminders that fit into your day. Built with women in mind, StackMate brings a little more ease to a routine that already has plenty of moving parts. YOUR STACK, BEAUTIFULLY ORGANIZED Add what you take from a library of nearly 200 peptides, vitamins, minerals and botanicals, each with its own page: what it is, route, half-life, storage and sources. Set daily, weekday or custom days, days on and off, weeks on and off, or a set length that counts Day 12 of 30. SNAP THE VIAL Photograph a vial label and StackMate AI reads the name and amount for you to check. Vial math shows units on a U-100 syringe from the numbers you enter, and keeps past vials when you start a new one. A LITTLE LESS TO REMEMBER Today shows what's scheduled, what you've logged and what's still ahead. Log a dose with the site on a front and back body map, and see where you logged that compound last time. GENTLE REMINDERS A quiet nudge when it's time. Discreet notifications keep the names of what you take off your lock screen. SEE YOUR RHYTHM A calendar of complete, partial and missed days, weekly insights, check-ins on how you feel, and weigh-ins on a simple chart. YOUR RECORDS, IN THE SAME PLACE Bring in bloodwork, InBody and DEXA pages. StackMate AI reads the printed values and the lab's own ranges into a record you can check and edit, and lines them up across visits and labs. LEARN AT YOUR PACE Short lessons on syringe units, reconstitution, half-life, storage and reading lab ranges, with drawn diagrams and a Listen button. A KIND COMMUNITY Optional. Share your week with photos or a short video, follow friends and cheer each other on. No medical advice and no selling, with reporting and blocking built in. ASK STACKMATE AI Ask about your own data and get a plain answer drawn from what you logged. It describes; it never advises. Off until you turn it on. YOUR DATA, YOUR CALL StackMate works fully without an account. Sign in with Apple or Google only if you want a cloud copy, the web view or Community, and delete your account any time. Your stack, made simple. StackMate is a tracking and organization tool and does not provide medical advice or suggest treatments or dosages. Check with your clinician before starting or changing any medication, supplement or peptide routine. Terms: https://stackmate.rork.app/terms Privacy: https://stackmate.rork.app/privacy

Verdict
The clearest difference is update cadence: StackMate at weekly against One Athletics's every 5 weeks. One Athletics's advantage is device support (4 vs 1) and iOS requirement (15.5 vs 18.0). On price, ads and in-app purchases there is nothing between them.
