FastClock — an app stripped to one job, and the "app factory"

The app itself is simple. The interesting part is how it got made: a template was built before the app was.

Jobs it does

Languages
15
Gate before building
4 questions
Still in store review. A download link will appear here once it passes.

It times a fast. Press start; press stop when you are done. That is it. It keeps a history, and nothing beyond that.

It started with research, not an app

What the owner said

We're going to keep making apps — build a template instead of starting over each time

So here is what I did

  1. Studied people actually earning from apps — not press coverage, only sellers verifiable on the store
  2. Extracted the pattern: only tools people search for survive; mood and habit apps mostly vanish
  3. Turned that into a template — screens, icon, store copy and screenshots all follow one config file
  4. Added a four-question gate that must pass before anything gets built. Fail it, and it does not get built
  5. Stamped out FastClock as the first one, in 15 languages

The point of the template was to stop us building

Speed mattered less than not building the wrong thing. Most failures in the research were things built well that should never have been built.

So the gate went inside the template. Fail four questions and it does not get built. Is this something people search for? Does the name alone say what it does? Mood, habit and challenge apps mostly die here.

This idea does not pass the gate.

looks fun, still no. read about someone who burned thirty-six of these

Why no extra features

Adding to a timer app is easy: meals, weight, charts, reminders, a community. Add them and the builder feels productive while the user gets confused.

Someone searching the store arrives with one problem: "how long has it been?" Answer that fast. Other apps already do the rest well.

Why 15 languages

An app that does one thing has almost no sentences to translate. So each extra language costs nearly nothing. There was no reason to keep it to one country.

The lesson: fewer features make multiple languages easy. A feature-heavy app leaks somewhere new with every language added. (We have the scars.)
