PepLog is a medication reminder & logbook for people who manage a peptide protocol and want to keep track of their progress & history. It's built around one idea: recording a dose should take seconds, right when it happens, the way a food tracker works. WHAT YOU CAN DO • Log a dose in a couple of taps: amount, time, injection site, and a note • Reconstitution made clear: enter a vial's contents and the water you added, and PepLog derives the concentration and converts the dose amount you enter into syringe units • Track your vials: see how much you have left as you log, when each vial was mixed, how long ago, and what 1 mg measures in it. Finished vials remain in your history • Progress photos: capture on a repeatable angle, compare any two side by side, and watch your timeline build over months • See what you've invested: record what a vial cost and PepLog shows your real spend, your cost per logged dose, and how much of what you mixed you've used • Set reminders on your own schedule, with multiple times a day, and log or snooze straight from the notification • See your consistency: a logging streak, badges, a week view, and a history of everything you've recorded • Track your weight and hydration over time, with your own optional goals NEW IN 1.4.2 - A fresh turquoise design throughout PepLog, with light and dark mode, an updated app icon, and refreshed logos. - Tap the sun or moon next to your profile to switch themes, or tap your profile to open Settings directly. - Vial details show when you mixed, time since mixing, and what 1 mg measures in syringe units. - Stats now defaults to 30 days with a cleaner layout. - Additional injection-site choices include left and right waist and lat, and Sign in with Apple reliability has been improved.

Verdict
The clearest difference is in-app purchases: PepLog at none against Dose's 3. PepLog also leads on review sentiment (100% vs 75%). Dose's advantage is rating (4.7 vs 4.4) and ratings volume (99 vs 25). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Dose sells 3 in-app purchases, starting at $4.99 per month. PepLog asks for nothing beyond the download.
Dose holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 99 and 25 respectively. Written reviews complicate that: 75% of Dose's written reviews are positive against 100% of PepLog's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 19, 2026 and October 8, 2026 respectively.
