Cooldown & Repeat

Cooldown is the simplest way to track anything that has a

refractory period. The app has one job: tell you, at a glance,

how long until you can do something again.

Tap when you took it. Watch the ring fill up. Get a ping when it

hits Ready. Reset and repeat.

WHAT IT'S FOR

• PRN ("as needed") medications — ibuprofen every 6 hours,

antihistamines, the emergency inhaler

• Daily supplements and vitamins

• Caffeine pacing — coffee, tea, or that one energy drink

• Watering plants, fertilising, repotting cycles

• Sunscreen reapplication

• Hygiene routines — shaving, flossing, contact lens swaps

• Anything else with a "how long ago did I…" question

THE RING

Every cooldown is one ring. The ring fills as time passes:

• Red — you just reset, can't reset again immediately

• Amber — cooling down, getting closer

• Green — Ready, tap to start the next cycle

Same visual on the phone, the widgets, the lock screen, and the

Apple Watch. One pattern, learn it once.

WIDGETS

• Home screen Small — one cooldown, big ring, tap-to-reset on Ready

• Home screen Medium — three cooldowns side-by-side

• Lock screen — circular, rectangular, and inline complications

APPLE WATCH

A native watchOS app with the same list-and-detail interaction as

the phone. Reset from your wrist; the change syncs back to the

phone instantly. Plus four complications:

• Circular — ring + emoji

• Rectangular — name + live countdown

• Inline — single line above the watch face clock

• Corner — ring tucked into a watch-face quadrant

SIRI

"Hey Siri, Cooldown reset Coffee."

"Tell Cooldown to reset Vitamin D."

The reset runs without launching the app — quick and quiet.

ICLOUD SYNC

Every cooldown syncs across your iPhones and iPads automatically

via your private iCloud account. Nothing is uploaded anywhere

else. The Apple Watch syncs through its paired iPhone.

PAY ONCE, OWN IT FOREVER

One up-front purchase. No subscriptions. No in-app purchases. No

premium tier. No ads. The app you buy is the app you keep — the

one you'll see in three years is the same one you bought today,

just a little more polished.

PRIVATE BY DESIGN

• No accounts, no signups, no login screens

• No analytics, no telemetry

• No tracking

• Your data lives on your devices and your iCloud — that's it

DESIGNED FOR "AS NEEDED"

Cooldown is built for the opposite of a fixed schedule. If you

take something at 8:00 and 20:00 every day without fail, a

scheduled-reminder app is the right tool. If you take something

only when you need it — every few hours at most — and want to

know how soon you can take it again, that's exactly what Cooldown

does.
