Review Highlights

  1. "This is a simple finance app that does everything you need to keep track of your finances. Hard to keep tabs of a budget with all the monthly review style apps. Having a daily, weekly, monthly view is so clutch! One feature I can’t wait for is tracking multiple cards."
  2. "I love this app! I love the simplicity and at a glance usefulness. The only thing on my wishlist would be to either toggle from one week to two or add two weeks to the main screen. Would be helpful for us biweeklies but I wouldn’t want to add too much on the main screen and defeat the whole purpose."
  3. "Love using this daily to get a quick idea of how I’m doing this week/month without logging into an app! If you’re having trouble connecting Amex with Teller, the app also supports Plaid for API sync! Brilliant concept executed simply."
  4. "Lightning fast response time updating transactions and extremely well thought out interface."
  5. "Super helpful to see my spending first thing in the morning. gives me a jolt of stress to be more cost effective in my day. Thank you Big Numbers!"
  6. "This app makes tracking your spending as simple and straightforward as possible. You now have no excuse for not doing it!"
