Vial is a private logbook for peptides. Keep your vial details, dose history, injection sites, and schedules in one place. Record the vials, pens, and other formats you have on hand, and save their details for future entries. Log your compound, amount, injection site, and time. Reuse your last logged amount to save time. The interactive 3D body map lets you mark an exact location and highlights your most recent site in a distinct color. Create daily, weekday, interval, or on/off schedules. Open the log form, snooze a reminder, or skip an entry from a notification. Reminders clear when you log the matching dose, and your history shows which scheduled entries you logged, missed, or skipped. Track remaining amounts, cost per mg, and estimated days of supply. Get low-stock alerts and manage pens, oral, nasal, and topical formats alongside vials. View weight, HRV, resting heart rate, blood pressure, and sleep from Apple Health alongside your dose history. Record daily check-ins for mood, energy, and sleep quality, and keep a log of side effects. Save progress photos and browse them by date. Record bloodwork with values, units, and reference ranges, then chart individual markers over time.

Verdict
The clearest difference is review sentiment: Vial at 100% against Peptide Tracker's 50%. Vial also leads on monetization model (freemium vs subscription). Peptide Tracker's advantage is rating (4.7 vs 3.4) and ratings volume (177 vs 5). On price, update cadence, ads and in-app purchases 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. Peptide Tracker sells 10 in-app purchases, starting at $7.99 per 7 days and Vial sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Peptide Tracker holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Peptide Tracker has 177 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Peptide Tracker's written reviews are positive against 100% of Vial's, so the app with the better star average is not the one people write more warmly about.
Peptide Tracker ships an update weekly, Vial every 11 days. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
