Repeated injections in the same site cause damage. Drop helps you rotate properly, log every dose, and stay on top of your treatment.
Care in every injection.
Repeated injections in the same site cause real damage: lipohypertrophy, scar tissue, and reduced absorption that affects how well your medication actually works. Drop makes proper rotation simple, so your treatment stays effective.

We've added Spotlight support for your injection history, letting you jump straight to any injection from a search. Siri shortcut suggestions are now seeded automatically after each injection, making it even faster to log with your voice.
Finally, we've improved haptic feedback throughout the app, polished the Add Injection and Add Medication flows, and fixed a number of bugs to keep things running smoothly. Thank you for using Drop!
