Free Peptide Tracker App
Peptrack is a peptide and GLP-1 tracker that is free all the way through: a dose log, vial inventory, reminders and a reconstitution calculator, with no subscription, no in-app purchases and no ads.
For research, informational and record-keeping reference only. It keeps your records and does arithmetic on the numbers you enter. It is not medical advice.

Free, without the asterisk
“Free” on an app store often means free to download. Here it means the whole app, for as long as you use it.
No subscription
Nothing to subscribe to, monthly or yearly, and no free trial that quietly ends.
No in-app purchases
There is no paid tier, so there is nothing to unlock. The app you download is the whole app.
No ads, no ad trackers
No banners, no sponsored compounds and no advertising SDKs. We do not sell your data.
No limits
Add as many vials, protocols and log entries as you like. Your history is never capped.

How “free” tracker apps usually work
Most trackers are free to download and then limit the free plan, often to a set number of compounds or protocols, with a subscription to lift the limit. That is a fair way to fund an app. It is just worth knowing before you put months of records into one.
Peptrack has no limit and no paid plan. It is also a new app, and other trackers do things it does not, such as blood work tracking or a web app. We wrote up the differences, with sources and without a ranking, so you can pick what suits you.
