About
Vialkeep is a peptide tracker and reconstitution calculator for iPhone. It does the syringe math on the numbers you enter and keeps the record. It ships with no dosing database, no presets and no suggested amounts. Every figure in the app is a figure you typed.
Built for people running peptide, GLP-1 or TRT protocols who want the arithmetic checked and the log kept, without an app telling them what to take.
WHAT IT DOES
Reconstitution calculator. Enter vial strength, diluent volume, your target dose and your syringe. Vialkeep returns the units to draw and the volume in mL, and marks the fill point on a drawing of the syringe you selected, U-100 or U-40. The working is written out so you can check it against your own arithmetic. Nothing is rounded silently and no unit is converted on your behalf.
Today. A timeline of every dose due, solid through what has happened and dashed through what is ahead. Shows what is still on board, how many doses remain in the vial, and how many days that is.
Calendar. A month grid with a mark on every dose. Tap any day to log retroactively, which matters if you tracked on paper for a week. Filter by peptide. Export the entire record as a CSV file.
Vials. Every vial you have mixed, with its concentration and a countdown to the expiry date you set yourself.
Schedules and reminders. Set a cadence and get a local notification on your device.
Injection site rotation. Record where each dose went and see what you have been using.
WHAT IT DOES NOT DO
No dosing database. No peptide arrives with a suggested amount attached.
No AI advisor and no chat.
No recommendations of any kind. It performs arithmetic on numbers you supply.
No account, no login, no email address, no advertising.
No dose, peptide name or injection site is ever sent to us. Those records stay on your device and are not transmitted to any server Cloud Motion Lab operates.
WHO IT IS FOR
People tracking research peptides such as BPC-157 or CJC-1295, people on GLP-1 medication who want their own record rather than a clinic's, and people on TRT who reconstitute their own vials. If you want an app that suggests what to take or how much, Vialkeep is the wrong app and says so.
MEDICAL DISCLAIMER
Vialkeep is not medical advice, not a medical device and not a substitute for a licensed clinician. It calculates only what you enter, so a wrong number in produces a wrong answer out. Always verify any calculation independently before acting on it. Decisions about what to take and how much belong to you and a qualified healthcare professional. Many substances people track are prescription-only or restricted where you live, and determining what is lawful and appropriate for you is your responsibility.
Vialkeep is free. Age 18+.
