■ FAQ

Q. How often should I replace my toothbrush?

Every 3 months is the common recommendation — Reflow's presets already reflect

it, so register once and the reminder takes care of the rest.

Q. Can each item have its own replacement schedule?

Yes. Set a custom cycle in days for every item — shower filter, water filter,

air filter, anything.

Q. Where is my data stored?

Nothing leaves your device. All replacement history is stored locally — no

account, no sign-in.
