Case study· not released

Never forget your tea again.

TeaTime times every cup you brew and lets you know when it's ready. Pip, a little cup, keeps an eye on things while you get on with your day.

What TeaTime does

TeaTime runs several teas at once, knows how long each one needs, and tells you the moment your cup is ready. No account, nothing to set up.

Two TeaTime screens: several timers running and the My Tea Collection grid

Several teas at once.

Green tea for you, black tea for Alex. Every cup gets its own timer and its own name, and the one that's ready first stays on top.

Pip, the little cup, telling you that your tea is ready

Pip lets you know.

When a cup is ready, Pip says so, by name. You see it on the Lock Screen and in the Dynamic Island too, so you don't have to keep the app open.

Tea picker listing your teas, each with its own steep time

Every tea, the right time.

Pick a tea and its steep time comes with it. Add your own teas with a photo and notes, or set a custom timer in 15-second steps.

Brewing journal sheet where you rate a cup from one to five stars

Learns how you like it.

Rate your cups in the brewing journal. After a few ratings, TeaTime suggests the steep time you liked best.

Case study

Built it. Tested it. Stopped.

TeaTime made it to testing on real iPhones. Then I asked whether enough people actually wanted it, and decided not to launch.

Built

Designed and coded solo

SwiftUI, Live Activities, widgets and Pip, from the first sketch to TestFlight.

Tested

A real demand check

Before going further, I checked whether people would actually switch to a new tea timer.

Learned

Demand before code

Next time I validate the problem first and build the app second.

FAQ

Questions about TeaTime.

Can I download TeaTime?

No. TeaTime never made it to the App Store. I stopped the project in October 2026 because there wasn't enough demand.

Did it need an account?

No. There was no sign-up, and your teas stayed on your iPhone.

Which devices did it run on?

iPhone. TeaTime came with Home Screen and Lock Screen widgets and a Live Activity for the tea that's brewing.

Who made TeaTime?

I'm Tim, and I design and build apps on my own under the name one human. TeaTime started as a timer for my daily green tea.
