Frequently asked questions and direct developer assistance for Peptide Calculator: VialCalc.
Does VialCalc require internet or a user account?
No. VialCalc operates 100% offline. There are no account registration requirements, passwords, or cloud servers. All your calculations remain private on your device.
How do I restore my Lifetime Pro purchase?
Open VialCalc, navigate to Settings, and tap "Restore Purchases". StoreKit will verify your Apple ID receipt and restore all unlocked features immediately.
How does the Reverse Diluent Solver work?
Instead of guessing water volume, enter your target compound dosage (e.g. 250 mcg) and your desired graduated scale tick-mark (e.g. 10 units). VialCalc will mathematically back-solve the exact diluent water volume needed.
