Private by default.
No cloud account to manage or data to be stolen.
No income definition or confusing settings.
Add budgets, expenses, and see the total spent and what's left.
You can easily share it with your family or housemates.
All features revolve around automation and providing less stuff to do or configure, so you have things like automatic budget categorization (based on previous expenses), automatic budget copying for the following month, and there's also a public API (beta) for you to make automations like recurring expenses (via Zapier, IFTTT, or other workflow automation tools).
Additionally, you can import and export budgets and expenses via JSON, and all the apps have their source code available in GitHub, so you're not locked-in.
