A free, private tracker for cycles, wellbeing and progress. Everything stays on your phone.
The cycle tracker, wellbeing scores, weight log and progress photos, all in one place.
Tap any screenshot to view it full-size.
No subscriptions, no upsells, no catch. Built because I wanted a proper way to track my own protocols without handing my data to anyone.
All data is stored exclusively on your device. Nothing is ever transmitted, uploaded or shared: no cloud sync, no servers, no accounts to breach.
Open it and start tracking. There is no login, no email capture, no onboarding funnel. Just the tool.
Full control, GDPR-friendly by design. More → Delete All Data wipes everything instantly, no questions asked.
Everything built around real personal research, not a dosing app, not medical advice.
Log and monitor personal cycles from start to end date. Record items in each cycle, set duration, and track progress day by day with a visual indicator. Active cycles show at a glance on the home dashboard.
Log four daily scores: Energy, Sleep Quality, Mood and Recovery, each rated 1 to 10, with 7-day trend charts so you can spot patterns over time.
Track body weight over time with kg or lbs support. See a 7-day trend chart alongside your full entry history.
Capture and store progress photos privately on your device. Never uploaded, never shared.
A straightforward maths reference tool that calculates concentration and volume from vial size and liquid volume inputs.
Copy your cycle data to clipboard and drop it straight into ChatGPT, Claude, Gemini or Perplexity for your own analysis, or export a full PDF report for your records.
My Peptide Pal is a web app (PWA) — no App Store or Play Store needed for the full experience. Install it in under a minute.
Privacy first: My Peptide Pal does not collect, transmit or store your data anywhere but your own device. No account, no cloud sync, no analytics tied to your entries.
Why isn't this on the App Store? Google now wants a full registered business behind any app like this. Fair enough for the big commercial ones, but that's not what this is — I'm not a business, I just build free tools for people trying to sort their own fitness and health out, same as everything else on irishpeptides.ie. Rather than jump through that hoop, I built it as a web app instead. Same features, install it in a minute, no store needed, no headache.
