Reminders that actually reach you
A nudge before each dose, one on time and one if you miss it. On iPhone they arrive as Time Sensitive, so Focus modes let them through. Water, meal and sleep reminders are there when you want them.

#1 Peptide TrackerHealth & Fitness
A quiet peptide tracker for every dose and every vial.
PepLabo is a peptide tracker that logs your doses, watches what is left in each vial, does the reconstitution math and reminds you on time. Pep, a small porcelain lab companion, keeps watch.

Last dose: yesterday, 21:00
Open the app and your day is already arranged.
Five screens do most of the work. Scroll through them the way you would use them.
-
Today, at a glance
Your next dose counts down live. The last one shows how long ago it was and where it went. Logging the next takes two taps.
-
A vial that feels real
Every vial on your shelf shows how much is left and roughly how many doses remain. Point the camera at a label and the text is read on your phone.
-
Programs and cycles you set
Your own times, on and off cycles and breaks, laid out on a weekly grid. PepLabo never suggests a dose: the numbers always come from you.
-
Ask Pep about your logs
With Pro, Pep answers questions about your own records. Dose and medical questions are declined, and nothing leaves your phone until you confirm.
-
On your home screen and lock screen
Next Dose, Vial and Weekly Lab widgets, a dose window in the Dynamic Island, and a Log dose control on iOS 18.
Reconstitution math, done before you draw.
Enter what is in the vial, how much water you add and the dose you were told to take. PepLabo shows the units on your syringe. It converts units; it does not decide anything for you.
A unit converter, not a dosing guide. Check every number with your clinician or pharmacist. Open the full calculator
Everything else your routine touches.
Travel without losing the thread
Pick your destination on the globe and choose how to handle the time difference: keep home time, switch to local time or shift gradually. Your reminders follow, and a packing list counts what to bring.

Reviews from the App Store and Google Play.
The only tracker I kept
I tried three apps before this one. PepLabo is the first that understands vials: it shows how many doses are left and warns me before I run out. Logging takes two taps.
Reconstitution without the stress
I used to redo the math every time I opened a new vial. Now I enter the amount and the water once and the syringe units are right there. Huge relief.
Site rotation finally makes sense
The body map shows where I injected last and the heat map keeps me from using the same spot. My skin is thankful.
Travel mode is underrated
Flew from New York to Tokyo and my reminders shifted gradually with the time difference. I did not miss a single dose.
Calm, private, beautiful
No account, no ads, and everything stays on my phone. Pep is adorable without being annoying. It feels like a premium app.
My doctor loved the report
I exported the PDF before my appointment and we went through every dose, site and note together. Worth Pro for that alone.

Meet Pep.
Pep is a small porcelain figure with three frosted glass spheres on its antenna. It does not talk. It notices.
Its spheres glow when it is thinking. It gets thirsty when you skip water, celebrates a streak with you, and on Sundays shows you how the week went.

Yes. PepLabo is available for iPhone on the App Store and for Android on Google Play. Some extras, like the Dynamic Island and the Log dose control, are iPhone features.
Do I need an account?

Where are my records stored?
On your phone. PepLabo has no analytics, advertising or tracking SDKs. Apple Health data is read on the device and never written to. When you use Pep AI, you see and confirm what is sent first.
Does PepLabo recommend doses?
No. PepLabo never suggests a peptide, a dose or a treatment. The numbers always come from you or your clinician; the calculator only converts units. PepLabo is a tracking tool, not a medical device.
Which peptides and medications can I track?
Any you enter yourself, in vials, pens, cartridges or other forms. The built-in library helps you find names, brands and codes even with typos, and is meant for education only.
Can I use PepLabo for GLP-1 medications?
Yes. You can log GLP-1 pens or vials, keep a weekly schedule, rotate injection sites and track weight alongside. PepLabo does not give medical advice about these medications.
What happens to reminders when I travel?
With travel mode (Pro) you pick your destination and how to handle the time difference. Your saved dose reminders follow that choice.
How do I cancel PepLabo Pro?
