Pep AI vs Dosely vs Pepti AI: peptide & GLP-1 tracker comparison
Pepti AI: Tracker App is a peptide & GLP-1 tracker for iPhone by Mister Business Enterprises.
Pepti AI: Tracker App is a different app from "Peptides Playground - Pepti AI", "Pep AI", "PepAI: Smart Peptide Log" and "Peppi AI", which are made by other developers.
Pep AI and Dosely are the two established peptide and GLP-1 trackers on the App Store; Pepti AI is a third option launching late 2026 with a free core, no account, and on-device AI. Pep AI leads on rating count (4.73 from 3,983 ratings) and features like meal photo scanning and a community; Dosely offers cost per dose and a stack-conflicts reference; Pepti AI's pitch is that it never locks your log and never had a dose calculator to remove. This page compares them on App Store data and on what their own reviews say.

What earns 4–5 stars for the incumbents
Worth saying plainly: both apps earn real praise — fast one-tap logging, clean UIs (before Pep AI 4.0), Dosely's fridge linking vials to protocols, multi-compound stacks and blends, reliable reminders, logging past and missed doses, site tracking, weight and nutrition in one place, the PK level chart, doctor exports, and developers who answer and ship fixes in days. Pepti AI's design borrows the good parts and targets the complaints.
Who should pick which app
- Pick Pep AI if you want meal photo/menu scanning, a community, and the biggest rating base — and the 3-day trial followed by a hard paywall suits you.
- Dosely includes cost-per-dose figures, a stack-conflicts reference, and label titration ladders. These describe Dosely's features; they are not a recommendation to use a dosing aid. Its onboarding leads from a questionnaire to a paywall.
- Wait for Pepti AI (late 2026) if you want a free core with no account, a quiet adult design, private on-device AI, protocol-level scheduling, late or skipped missed-dose logging, and an app that is upfront about having no calculator.
Other trackers worth knowing
This page compares three apps, but they are not the only options. Larger GLP-1 and peptide trackers on the App Store include Shotsy (about 34,000 ratings), PeptidePal (about 4,900) and PeptIQ (about 950), as listed on 28 October 2026. If a large user base matters most to you, look at those too.
FAQ
Which has the most users?
Pep AI shows the most ratings by far: 3,983 at 4.73, versus 108 at 4.63 for Dosely. Apple only publishes recent written reviews (152 for Pep AI, 25 for Dosely); the star-only ratings are not readable, so we cannot compare actual user counts.
Which is cheapest?
Annual plans: Dosely $19.99–39.99 (it runs many price tests), Pep AI $29.99–49.99, and Pepti AI at proposed launch pricing of $29.99/year with a 7-day trial, $4.99/month, or $59.99 lifetime. Pepti AI's core is free either way — check the billing period before any trial.
Which works on older iPhones?
Pep AI needs iOS 16.4, Dosely 17.0. Pepti AI's on-device assistant needs iOS 26+, with a rule-based card flow on other devices.
Why do both apps lack a dose calculator now?
Apple App Review guideline 1.4.2 allows drug-dosage calculators only from approved sources; both removed theirs in September–October 2026. Full story.
Which is best for GLP-1 shots specifically?
All three are log-only trackers for GLP-1 medications and peptides; none suggests doses, and none of them makes claims about whether any peptide works. Pep AI adds meal scanning; Dosely adds cost per dose; Pepti AI adds a free core and on-device AI.
Which respects privacy most?
Compare the App Store privacy labels: Pep AI lists third-party advertising (device ID) and analytics (usage data); Dosely lists third-party advertising (purchases, email, user ID, device ID). Pepti AI has no ads and keeps the log in a local encrypted store with user-held backups.
Should I wait for Pepti AI?
If the paywall, redesign, data-loss, or AI-cap complaints in the incumbents' own reviews ring true, Pepti AI is designed around exactly those — it ships late 2026.
