PepVault vs Pep AI

Last updated October 2026
The short answer
Pep AI centers on day-to-day GLP-1 tracking (food with photo meal scans, water, side effects, sleep and mood), has 3,954 US ratings averaging 4.7, and runs on iPhone and Android. PepVault adds bloodwork tracking and an AI coach that reads your protocol, labs, training, food and recovery together; it's iPhone-only and much newer (4.9 from 8 ratings). PepVault is $69.99 a year or $14.99 a month, with 7 days free on the yearly plan for new subscribers; Pep AI lists $9.99 a month.
Free alternatives to Pep AI
Pep AI needs a subscription for tracking. For GLP-1 shots with food and side effects, MeAgain's free version logs food by photo, barcode or voice, and Shotsy's core features are free. For peptides, Peptide Tracker Log & Reminder is free with no subscription, and Regimen is free for one compound. Pep AI removed its dose calculator in October 2026; PepVault's reconstitution calculator is free on the web with no signup.
