About Peptly
Last updated
What is Peptly?
Peptly is a free iOS peptide reconstitution calculator built by Baris Bingor, an independent app developer. It computes the exact units to draw on a U-100 insulin syringe given vial mass, bacteriostatic water volume, and target dose — with a visual syringe view. The app is research-framed reference only, runs entirely on-device, 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.
The app solves one problem cleanly: convert a lyophilized vial + bacteriostatic water + target dose into exact units to draw, with a visual syringe so the draw mark is unmistakable. Everything else — the injection log, saved mixes, reminders — exists because it makes the core math easier to use over time, not because it adds AI chatbots or cloud sync.
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 doses, cycles, or compounds. Values shown are arithmetic outputs only.
- Not cloud-connected. There is no account, no sign-up, and no server-side log. Your data 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 reconstitution mix you save, every injection you log, 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 contents of your injection log or saved mixes. 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 in the App Store under the Medical / Reference categories, age 12+. All on-page content treats reconstitution as arithmetic — not as medical advice or dosing prescription. Consult a licensed clinician before any injection.
