- Blends: calculate for vials with 2 to 6 components. Enter each component and its amount, and see what one measurement contains. - Back up your data to a file and restore it on a new phone. - Delete a record added by mistake. - Protocols: several times a day, an end date, and a default vial for one-tap recording from reminders. - Inventory: see how long a vial will last, with alerts before it expires or runs out. - App Lock: choose how soon the app locks. - Fixes: entries are no longer marked "Not completed" early, reminders are more reliable, and many smaller improvements.
