These ideas are for web applications. Each includes a first screen to build and a reference product. Test the workflow with a user before adding complex accounts, a native mobile app or automation. No mobile download metrics are used here.

Useful questions

Which app should I build first?

Choose a task you see repeated. Have someone complete it in a prototype and observe where they get stuck.

Can I start without coding?

Yes, for some forms, portals and simple workflows. Check permission, export and integration limits before selling.
