Peptide Protocol is a shot log for people following a peptide or GLP-1 routine their clinician set. Log every dose in seconds: the compound, the amount you took and the injection site, exactly as you enter them. Get reminders at the times you choose. Rotate injection sites with a body map that shows where you went last. Keep track of your vials: what you have on hand, mix and expiry dates, and refill alerts before you run out. Check in on energy, sleep, appetite, side effects and weight, and see your own logs side by side week by week. Works for semaglutide, tirzepatide, BPC-157, CJC-1295, ipamorelin, GHK-Cu and 30+ more compounds. Pause a protocol with a return date and it picks up again on the day you choose. Your records stay on your iPhone. IMPORTANT Peptide Protocol is a personal log. It does not compute, suggest, recommend or adjust doses, and it does not provide medical advice, diagnosis or treatment. Enter the dose and amounts your prescriber gave you, and talk to a qualified healthcare professional before any medical decision.

Strand is the hybrid training log for people who lift, run, swim and race. Track GPS runs, log every gym session, run hybrid circuits with a live split timer, see daily readiness from your watch and count calories, all in one app. Most workout apps only care about one sport. If you do strength work and cardio, your week ends up split across three apps that don't talk to each other. Strand puts it all in one training log, so you can see your whole week and know when to push and when to back off.

Verdict
The clearest difference is monetization model: Strand at freemium against Peptide Protocol's subscription. Strand also leads on ads (none vs shown) and iOS requirement (15.1 vs 18.0). Peptide Protocol's advantage is ratings volume (14 vs 1) and update cadence (every 5 days vs every 11 days). On price, rating, in-app purchases 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. Peptide Protocol sells 11 in-app purchases, starting at $4.99 per 7 days and Strand sells 6 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Peptide Protocol against 5.0 for Strand. That said, the two scores are not equally well evidenced: Peptide Protocol has 14 ratings behind it against 1, so its average is the more settled of the two.
Peptide Protocol ships an update every 5 days, Strand every 11 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
