My Bills

Built around one clear number.

Everything in My Bills exists to answer one question: what can you safely spend right now?

Current Balance Income still to come Bills still to come Safe To Spend

Current Balance is entered manually. Marking a bill as paid or income as received updates what remains to come, but never changes your Current Balance automatically.

Bills and income, tracked properly

Log recurring bills, one-off costs and Flexi items whose amount can vary, then tick them off as they're paid or received. Overdue and completed items are always easy to find.

A calendar for what's due

See bills and income for the month at a glance, with reminders so nothing catches you out — plus savings pots and custom budget periods to plan further ahead. Custom Categories and unlimited items are part of My Bills Premium, a Google Play subscription.
