Pinly

Pinly is a calculator and logbook for people who keep their own record of injections. It works out volumes, remembers what was taken and when, and reminds you about a scheduled dose. Everything runs on your phone — no account, no sign-in, nothing sent to a server.

WHAT PINLY DOES

• Reconstitution calculator. Enter the vial contents and how much bacteriostatic water you added; Pinly works out the concentration, the number of doses and the units to draw on an insulin syringe. It warns you when a dose will not fit in one draw, or when too little is left in the vial.

• Vials. Every vial keeps its own level, mixing date and shelf life after reconstitution. You can see how much is left and how many doses that covers.

• Protocols and reminders. Set the days and times and Pinly reminds you about a scheduled injection. A reminder can be postponed or logged straight away.

• History and calendar. Every injection with its date, dose and site. History exports to a CSV file.

• Supplies. Syringes, needles and swabs count down on their own with every logged injection. The app tells you before they run out.

• Peptide database. Cards with a description, typical dose ranges and shelf life after mixing — as reference material.

• Progress. Weight and notes over time, on one chart with your injection history.

PINLY PRO

Everything above is free. The Pinly Pro subscription adds convenience and looks: accent colours, a custom notification style, a home screen widget, a dose escalation chart, a cost summary, an injection site rotation map and a PIN lock. Monthly, yearly or one-time lifetime.

PRIVACY

Vials, injection history, weight and notes are stored only on this phone. The app has no accounts, sends none of your data to any server, and contains no ads or analytics. Backups and CSV exports are made by you, to a location you choose.
