The #1 data-backed peptide app.
Log every dose. Pull in your bloodwork and your wearable. See all three on one timeline, and find out if your peptides are actually doing anything.
What are you working toward?
Most people open the app with one of these five in mind. Pick yours. We start with what the peptide does, in plain language, and get to the logging once you know why you’re taking it.
Weight and body recomposition
You want the weight to come off and stay off.
Read how GLP-1s and the other metabolic peptides work, in plain language. Then log doses, weight and how you feel, and look back on the weeks instead of guessing.
More energy
You want to stop running on empty by mid-afternoon.
Short guides cover the mitochondrial and metabolic peptides. A daily check-in puts what you did next to how you felt.
Better recovery
You want the hard session on Saturday without paying for it on Monday.
Read how a recovery protocol is usually structured, then see training and sleep land on the same week as the doses.
Better sleep
You want more mornings that start rested.
Sleep from your Oura, WHOOP, Garmin or Apple Watch sits beside the dose log, so a change in one shows up against the other.
Sticking to your protocol
You want to stop wondering whether Tuesday’s dose happened.
Reminders, one-tap logging from the phone or the watch, and a streak that notices when you miss.
Know what you’re taking before you track it
Most people arrive with questions, so the site starts there. The guides, the compound library and the calculators are free to read and use, no app needed. The app comes second, once you know what you’re doing and why.

Graded by evidence,
not by reputation
Most peptides sold today have almost no human data behind them. We label every one of the 57 peptides with how much research actually exists, and say plainly when the answer is very little.

| BPC-157 | SubQ | Extensive | 142 |
| Semaglutide | SubQ | Extensive | 89 |
| CJC-1295 | SubQ | Moderate | 34 |

Your protocol and your body, on one axis
See when something changed, not just that it did. Doses, side effects and workouts land on the same timeline as your labs.
Everything the app does, so the protocol has a paper trail
The paper trail
Doses, vials and the maths between them, on the phone or from your wrist. The log is what the rest of the app reads.
- 01Dose logEvery dose, route and site, with the vial it came from.
- 02VialsDoses left on every row, the expiry date, a refill reminder at three.
- 03ReconstitutionVial and BAC water in, units to draw out. No mental arithmetic.
- 04Apple WatchLog the dose from your wrist. Today’s rings, the streak and your vitals on the watch.
What goes in besides the peptide
Food, supplements and training, logged in seconds and read into the same week.
- 05NutritionCalories and macros. Snap a plate, scan a barcode, or type it in.
- 06Supplement scannerPoint the camera at the bottle. It reads the barcode, or the label.
- 07Supplement stackMorning, midday, evening. One tap logs the whole stack.
- 08TrainingWorkouts and activities on one weekly goal, Apple Watch sessions imported.
What your body says back
Bloodwork, the wearable and the scan, each on the same timeline as your doses.

Company, and a coach
Remi reads the lot. Friends keep the streak alive. Everything stays yours.
- 12Remi, your coachAnswers from your own log, with the research cited.
- 13CommunityFriend streaks, a room for every peptide, a weekly board. Doses stay private.
- 14PrivacyFace ID lock, export everything, delete on request.
A coach that reads your logs, not your mind
Ask Remi anything about your protocol. It answers from your own doses, labs and wearable data, and cites the research behind the compound. Never a number it did not read.
- Charts drawn from your own series
- Every claim tied to a reference you can open
- Says plainly when the evidence is thin
Fifteen things the app does
The chapters above are the short version. This is each piece explained properly, so you can hold it against any other peptide tracker before you install anything.
-
01
Dose log
Every dose is a timestamped row: compound, amount, route, injection site, cycle day and the vial it came from. Log it on the phone or from the Apple Watch. The log is the spine of the app. Labs, wearable data and Remi all read from it, so a dose you did not log is a dose the rest of the app cannot explain.
-
02
Protocol and stack schedule
Build a protocol with more than one peptide in it, set the frequency and the cycle, and the app turns it into a calendar of what is due and when. Reminders fire for each dose. A streak counts the days you kept to it, and a daily check-in records how you felt alongside what you took.
-
03
Vials and reconstitution
Enter the vial size and the bacteriostatic water you added. The app returns the concentration and the units to draw for the dose you want, in U-100 and U-40 syringe units. Every vial keeps a running count of doses left, an expiry date, and a refill reminder when three doses remain.
-
04
Injection site map
A body map records where each shot went and suggests the next site from healing time, so the same spot is not used twice in a week. Pain, swelling or bruising can be logged per site, which turns a vague sense that one area reacts badly into a record you can show someone.
-
05
Compound library, graded by evidence
57 peptides, each with its mechanism, the human and animal research that exists, dosing ranges reported in the literature, common stacks and contraindications. Every compound carries an evidence grade. When the honest answer is that almost no human data exists, the page says so instead of padding.
-
06
Apple Watch
Log a dose from your wrist without opening the phone. The watch shows today’s rings, the streak and your vitals. Workouts recorded on the watch are imported into the training log on the phone.
-
07
Nutrition
Calories and macros, logged three ways: photograph the plate, scan a barcode, or type it. Food lands on the same week as the doses, which matters for anything appetite-related and for anyone trying to hold muscle while losing weight.
-
08
Supplement scanner and stack
Point the camera at the bottle. The app reads the barcode, or the label if there is no barcode, and adds the supplement to your stack. Stacks are grouped by morning, midday and evening, and one tap logs the whole group.
-
09
Training
Workouts and activities count toward one weekly goal. Sessions from the Apple Watch come in automatically; anything else is a few taps. Training sits on the timeline beside doses and sleep, so recovery peptides can be judged against actual load rather than a feeling.
-
10
Bloodwork
Upload any lab report as a PDF. The app reads 36 biomarkers from it, including IGF-1, ApoB, HbA1c, hs-CRP and fasting insulin, and plots each one against the weeks you were on each compound. Two draws six weeks apart stop being two pieces of paper and become a line with your protocol drawn underneath it.
-
11
Wearables
Oura, WHOOP and Garmin connect directly, and anything that writes to Apple Health or Health Connect comes in the same way: heart rate variability, resting heart rate, sleep stages, recovery and activity. The point is not another sleep chart. It is seeing the sleep chart and the dose log on one axis, so a change in one can be checked against the other.
-
12
Body scanner
Track body composition with the camera on the phone you already own. Scans are dated and sit on the same timeline as weight, food and doses, which is the only way to tell recomposition from the scale going down.
-
13
Remi, the coach
Ask Remi anything about your protocol. It answers from your own doses, labs and wearable data, and cites the research behind each compound. It never produces a number it did not read from your log, and it never recommends a dose. That line is deliberate and it is where most AI health apps fail.
-
14
Community
Friend streaks keep people logging. There is a room for every peptide and a weekly board. Doses, labs and anything personal stay private; the community sees that you logged, never what.
-
15
Privacy and your data
Face ID or passcode lock on the app. Export everything you have ever logged as a file you own. Delete the account from the app or by request and the data goes with it: deletion is processed within 30 days, and backups are cleared within 90.
Every feature has its own page in the app guide. See the features page for the overview, or how it compares with the other peptide apps.
