Why this app exists
About Peptly
Last updated
What is Peptly?
Peptly is a private peptide log and tracker for iPhone and iPad, built by Baris Bingor, an independent app developer. You log each entry with the amount you type, shown exactly as you typed it; Today shows what's planned, with Log and Skip; reminders follow your own schedules; and it suggests your next injection site. It never calculates, suggests or recommends an amount, keeps your log on your phone, and never requires an account.
What Peptly is
Peptly is the tool I wanted to exist when I noticed how often peptide reconstitution math was done with a paper calculator, a Reddit screenshot, or a spreadsheet — all error-prone, none with a visual reference for the actual draw on an insulin syringe.
That math lives on this website: a free calculator that runs in your browser, with the formulas and worked examples beside it. The app does a different job — a private, clear log. Each entry holds the amount you typed, exactly as you typed it, with the site and a note; Today shows what's planned, reminders follow your own schedules, and Peptly suggests your next injection site. The app never calculates, suggests or recommends an amount, and there are no AI chatbots or cloud sync anywhere.
What Peptly is not
- Not a vendor. Peptly does not sell peptides and does not link to peptide vendors.
- Not medical advice. Peptly does not recommend amounts, doses, cycles, or compounds. Every amount in the app is one you typed.
- Not a calculator. The app never works out, converts or suggests an amount; the calculator on this website is a separate, free web tool.
- Not cloud-connected. There is no account, no sign-up, and no server-side log. Your log stays on your device.
- Not an AI chatbot. Peptly does not run an LLM that discusses dosing or medical decisions.
Privacy and on-device storage
Every entry you log, every vial you record, every weight you enter and every reminder you schedule stays on your iPhone or iPad. Peptly uses standard iOS analytics (Firebase + AppsFlyer) for aggregate usage signals like screen views and feature taps — never the amounts, sites or notes you enter. See the privacy policy for the full breakdown.
Who builds Peptly
Peptly is built by Baris Bingor, an independent iOS developer. Issues, feedback, and feature requests go to support — every email is read by a person.
Compliance line
Peptly is positioned for research and educational reference. The app is a personal log, rated 12+ on the App Store: it keeps what you enter and never works out, suggests or converts an amount. This website treats reconstitution as arithmetic — not as medical advice or dosing prescription. Consult a licensed clinician before any injection.
