Three steps. That's it.

If you can describe what you want, you can build it.

01

Pick an app you know

Browse popular apps by category. Fitness trackers, expense managers, habit loggers, recipe books. Choose the one closest to what you need.

02

Describe your changes

In plain English. "Remove the social features." "Add a column for notes." "Make it track my dog's walks too." Whatever you want.

03

Own it forever

Get a working app that's yours. No subscription. No ads. No data harvesting. Customize it anytime by just describing what to change.

You shouldn't need a computer science degree to make a simple app. And you shouldn't pay $10/month for something an AI can build you in two minutes. Dupl exists because everyone deserves software that works exactly the way they want.
