Piri is a private peptide tracker for iPhone. Log doses, cycles and injection sites in seconds, follow a protocol without counting days in your head, and keep a history you can actually search. No account. No cloud. Nothing leaves your phone. Forgot to log yesterday? Backdate it. Any entry can be edited or deleted afterwards, so a missed log is never a permanent hole in your record. WHAT YOU CAN DO • Log a dose in seconds — compound, amount, injection site and time • Record injection sites from a fixed list, left and right kept separate, so your history stays countable • See where your doses have actually gone, ranked by site, with how long since you last used each one • Follow a cycle-based schedule and see where you are at a glance ("Cycle 2 · Day 18") • Run more than one protocol at the same time • Backdate or edit any entry, however long after the fact • Check in daily on how you feel, with notes in your own words • Watch weekly trends, so day-to-day noise turns into something you can actually read • Sync body weight from Apple Health, or type it — you get the trend either way • Search your full history, however far back it goes • Get one daily reminder at a time you choose, and nothing else • Export a CSV or generate a full PDF report, built right on your device PRIVATE BY DESIGN • Your data never leaves your device — there is no account and no cloud sync • Face ID / Touch ID and a PIN, with the database encrypted at rest • A recovery code you keep, so a forgotten PIN doesn't mean a lost journal • Back up to a file you control, and restore it on a new phone • Apple Health sync is optional, covers body weight only, and can be revoked any time • The only thing that ever leaves your phone is what's required for purchases, licensing, and app updates BUILT TO BE SIMPLE No spreadsheets. No logins. No feeds, streak-shaming, or clutter. Just a calm, fast place to keep your routine straight and look back honestly. Piri is free to try. One purchase unlocks everything, forever — no subscription. IMPORTANT Piri is a personal journaling and organization tool only. It does not provide medical advice, diagnose conditions, recommend treatments, prescribe medications, or supply any substances. It never suggests, calculates, or changes an amount — you record what you decide. Always consult a qualified healthcare professional before making healthcare decisions.

Verdict

The call

The clearest difference is price: Piri at Free against PeptideJournal's $5.99. Piri also leads on rating (5.0 vs 4.3) and update cadence (every 2 days vs weekly). PeptideJournal's advantage is in-app purchases (none vs 1) and ratings volume (20 vs 2). On ads and device support there is nothing between them.
