Track your stack.
And theirs.
A free app that keeps track of your peptides and everything else you take on a schedule — and your partner’s, side by side. What’s due today, what’s in the fridge, what’s on order, and what you logged.
Free for one person, with every feature. Add a partner or family member with Peptivist Together — the first 14 days are free. Nothing is collected until you sign in.
Your data is never lost
Backed up as you go. Sign in on a new phone and it is all there, and you can export everything, any time, on every plan.
Free for one, for good
Everything for one person stays free. No feature that is free today will be moved behind a paywall. It is written into our terms.
Reminders you can trust
They ring with the app closed. A checklist makes sure your phone allows it, and a test button proves it in a minute.
In the app
Everything you currently keep in a spreadsheet, a notes app and three alarms.
One place for what is due, what you have, what is on the way and what you have done — shown exactly the way you entered it.
Today
What is due this morning and tonight, in the order this person actually lives their day. Tick it off when it is done — and if your partner ticked it first, it says so.
Schedule, timeline, calendar
Every day, certain days, every few days, or a cycle with a last day. Doses that step up over time, written the way you typed them. A month view of what got done.
Inventory
Vials, bottles and prescriptions — yours, or shared between two people. Sealed, in use, finished, went bad. Every dose shows which vial it came from.
Orders
Carrier and tracking number, shipped to delivered, didn’t arrive, replacement sent. When the box lands, check what came, note anything wrong, and it goes straight into your inventory. Anyone who shares that stock gets the alert.
Journal
Weight, measurements, water, food, training, sleep, notes, lab results and progress photos — in whatever units you already use.
People and sharing
Keep a profile for a partner who has their own login, or a parent who will never install an app. Choose what each person can see — schedule, inventory, journal — and take it back any time, instantly.
Reminders that know when you are done
A nudge before each dose, snooze, and follow-ups until it is ticked. A reminder when a vial reaches the use-by date you set. On the lock screen it says only “Peptivist” unless you want more.
What Changed
A record of every edit to a profile — what changed, who changed it, when. Nobody can alter or delete it, including you. In an app two people share, that is a safety feature.
Learn the basics
Short step-by-step walkthroughs of the real screens: add your first item, add a vial, share a profile. They sit on the Today screen until you have something scheduled.
Pinning for two?
Your schedule and your partner’s, side by side.
Every other tracker is built for one person. Peptivist keeps a separate profile for each person — a partner with their own login, a parent who will never install anything — each on their own daily rhythm, sharing the same stock.
- Everyone view. Both schedules on one screen, each in that person’s own order.
- Night shift. For someone who sleeps days, the app says Wake up and Before bed instead of Morning and Night, at the hours they actually keep.
- One shared stock. Both of you draw from the same vials. The app knows who paid, what is left, and who used the last of it.
- Who logged it. If your partner ticks a dose on their phone, yours shows it was them. No double entries.
- Take access back in one tap. It ends immediately. They are not asked, and they are not told.
The fridge
Know what you have, what is on the way, and which vial you are using.
- Vials, bottles, prescriptions. Sealed, in use, finished. Lot numbers, so if one vial from a batch went bad you can find the rest.
- Orders, start to finish. Tracking, didn’t arrive, replacement sent. When it lands, a quick check-in puts what came straight into your inventory.
- The life of a vial. Ran out? It offers the next one. Went bad? Note why, add a photo, and the app flags the rest of that lot.
- Use-by dates you set. Put a date on a vial and the app reminds you that morning. It never picks the date for you.
What it will never do
Peptivist never works out a dose for you. On purpose.
It keeps your records. It does not give advice. That rule shapes the whole app, and it is written into our terms, not buried in a footnote.
- No dose math. It does not convert syringe units to milligrams, calculate concentrations, or suggest amounts. Every number in the app is one you typed.
- No tracking software. No analytics, no ad tracking, no crash reporting. None.
- Your photos are just photos. Never measured, scanned or analysed. Location data is removed before upload.
- Export and delete are always free. From inside the app, on every plan. Your records are yours to take.
- No vendor lists, no affiliate links. We do not sell, recommend or get paid for anything you buy. Vendors you note are private to you.

SoonCommon questions
Things people ask.
What is Peptivist?
An app for keeping track of peptides and anything else you take on a schedule — for you, and for the people you look after. It shows what is due, what you have, what you ordered, and what you have logged. It works in your browser today; the iPhone and Android apps are coming.
Is it free?
Yes, for one person — every feature, with no limit on how much you track. If you want to add a partner or family member, that is Peptivist Together, up to six people, with a 14-day free trial. Founding Member is optional: a way to support the app if you want to, not something you need.
Does it give dosing advice?
No, and it never will. Peptivist does not do dose math of any kind: it cannot turn syringe units into milligrams, work out a concentration, or suggest an amount. Every number in the app is one you typed. It keeps your records; it does not advise you.
Is my data private?
Yes. There is no advertising or tracking software in the app at all. We never sell your data and never use health data for advertising. Your photos are stored as files and never analysed. The only sharing is what you set up yourself, and you can take it back instantly. Privacy policy · Consumer health data.
Can my partner see everything?
Only what you choose. Schedule, inventory, journal, lab results and photos, and the change history are each a separate switch. Someone who can see your schedule and nothing else cannot see your bloodwork — that is enforced where the data lives, not just hidden on a screen.
Who makes it?
