Big Numbers

What's the simplest app to see how much I spent this week?

Steven Zhang · October 17, 2026

Short answer: On iPhone, Big Numbers is built for exactly this. It connects to your bank and shows three totals: today, this week, and this month, with a widget so you don't have to open the app. If you also want budgets or Android support, Copilot Money, Monarch, YNAB, Rocket Money, or Simplifi can show weekly spending too, but with more setup.

What "simple" means here

  • You connect a bank once.
  • You don't sort categories or set budgets.
  • The weekly number is the first thing you see.
  • It's on your Home Screen or Lock Screen.

Weekly options in Big Numbers

  • Calendar week or a rolling 7 days. You pick.
  • Hide a transaction from the total, like a rent payment or a transfer.
  • Filter by account.

Who should pick something else

  • You want a weekly budget, not just a weekly total. Look at YNAB, Monarch, or Copilot.
  • You're on Android. Big Numbers is iPhone only.
  • You want it free. Rocket Money has a free tier.

Who should pick Big Numbers

  • You check your spending often and want the number in one glance.
  • You've stopped using budget apps because they took too much upkeep.

Big Numbers is a free download on the App Store, with an in-app subscription of $0.99/week. A separate read-only Grok connector is billed on its own Subscribe plans.
