Track GLP-1s, peptides, hormones and other injectable medications - simply, privately, without any ads and absolutely free. Now with weight tracking!
Injectly is the simple, yet powerful way to track your injectable medications. No ads, no subscription, and no tracking — just free help for staying on top of your regimen.
Log every injection, set reminders that match your cadence, and review your history in a calendar or list. No account is needed for any of this. A free account with Apple or Google syncs your data across devices and unlocks advanced scheduling, such as on/off cycles and custom intervals.
For supported medications, the Insights tab turns your logbook into a serum concentration view: an estimate of current and projected levels from the doses you've logged and your weight, how close you are to peak, and how much of the last dose is still active.
Your health data is always yours: never sold, never used for advertising, and you can export or delete it anytime.
Whether you're managing peptides, prescriptions, or personal health therapies, Injectly helps you log every injection, stay on schedule, and understand what's happening between each dose. Enjoy!
I like this so far, I recommended update needed for this would be on the cadence tab at the bottom below the cycle and titration options would be helpful if there was a small Notes field to be able to put in some specific information. Some meds require like take 30 to 90 minutes prior to bedtime, which is perhaps a different time every day or some of them say must not eat two hours before bedtime or need to eat with 40 g of carbs. You know some of the medication’s require some more specific instructions and we have nowhere to put that in here. From there on the saved medication screen for each medication at the bottom has a little square where you can click and edit pencil and right next to it is an alarm button that represents a schedule right next to that I would put another little square that looks like a little notepad that you could click on there that would take you right to the specific notes or the special instructions you have required for that medication they might also include specific needle sizes or specific injection locations, this would really show up this app!Additionally, it would be nice if you could have all of your medication’s that live in a “medicine cabinet” and you can pull them out of the cabinet to put them into a protocol.
Super easy to use and free!

I love this app unlike the “pep ai” apps which cost money, are annoying to use, have too much added things to make it look special. If you just need to track your injections this is the app you go for that is free and extremely easy to use. I have two peps that are nasal and even though it would be nice to have that option, it is basically the same thing since each spray is 100mcg on a nasal so I honestly don’t mind it. Love this app
The Only Pep App I Keep Coming Back To

Honest review by a long time user!! This is a great app, and honestly it's really all I'm using now. I wish there was a bit more info on certain peptides, but I'm sure future updates will fill that in. I've tried many peptide apps, and this is the only one I keep coming back to.I also want to mention that I sent in some suggestions to the developer and have received an actual email back!

Thanks for developing this wonderful app. I used to struggle with my research. I had to put it down in notes and got overwhelming. It allows you to input the mgs you are reconstituting and how much recon fluid. Then it calculates how much to use if you know the mgs or mcs you are injecting. Records when and you can put in notes where if you like. Easy peasy, like butter. Cant find a better app than this to use if you are researching peptides
This update is about App Store compliance, not new features.
Under App Store guidelines, only apps from drug manufacturers, pharmacies and similar institutions may compute doses. So Injectly no longer shows how many syringe units to draw. You enter the dose you take, as instructed by your prescriber or pharmacy, and Injectly logs it, reminds you and keeps your history as before. Everything else works as it did.
I know many of you relied on this. Thank you for your understanding.
