Starting with one useful feature

The first Pocket Ledger build: a small scope, a working prototype, and a list of things deliberately left for later.

The smallest useful version

In this fictional build log, the goal is simple: record a project expense and see it again tomorrow. No subscriptions, no charts, no elaborate onboarding.

The prototype needs a description, an amount, and a date. Everything else can wait until the basic interaction feels right.

What changed while building

Editing turned out to matter as much as entering data. A fast input form is only useful if a mistake is easy to correct. The next iteration puts those two actions on equal footing.

Next on the list

  • Add a clear CSV export.
  • Test the empty state with a first-time reader.
  • Explore a weekly summary before building more charts.

There are no revenue or customer claims here. This is a sample of how a side-project journal can capture decisions as they happen.
