ReflowNever forget a replacement again
"Wait… when did I last change this filter?" — never again.
Toothbrushes, shower filters, water filters, dish sponges — the things you always mean to swap but forget. Reflow remembers the cycle, shows remaining life as a gauge, and reminds you right when it's due.
Sound familiar?
You have no idea when you last changed the shower or water filter
Hygiene items like toothbrushes and razors get swapped way too late
Notes and alarms always fizzle out and you forget anyway
Reflow solves all of it ✨
No clutter. All about timing.
Add it once — the reminder takes it from there
Quick add with presets
Common items — toothbrush, shower filter, water filter, dish sponge — come with sensible replacement cycles built in, so you add them in one tap.
Remaining-life gauge
A circular gauge drains as the due date nears, so you can see exactly how much life is left right from the home screen.
Replace reminders
Get a notification right when a replacement is due — and set an early reminder a few days ahead so you can prepare.

Swapped it? Tap once. The gauge fills back up and the next cycle is calculated automatically.

Frequently asked questions
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.
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.
How does it remind me when something is due?
It sends a notification on the due date, and you can enable an early reminder a few days ahead in Settings. Just allow the notification permission.
What kinds of supplies can I track?
Hygiene items like toothbrushes, razors, and contact lenses; shower, water, air-purifier, and AC filters; dish sponges and towels; bedding and pillowcases; supplements; pet supplies — anything with a replacement cycle can be added with a custom interval.
