Helpful but not 100% accurate
The app is very helpful as it notifies me every time a card is charged. I have it set to notify me on all charges so can’t comment on whether the settings to restrict notifications or usage actually work. Occasionally, it would fail to notify or notify 2x. Credits to the card do not appear to show in recent transactions. Random Tax charges show up though not actually charged on the monthly billing statement (or on online banking). When in doubt, I check online banking. I also like that it allows me to add multiple cards for business and personal accounts.
