<prompt> Human: I know I should keep all receipts and reconcile them with my statement at end of the month. So if I go to a restaurant and get a bill for 100 and tip 20. I should save my receipt and when I get my statement match the 120 receipt with the 120 statement. I dont do that. Id rather not start doing that. At best I look at my statement and think ehhh yeah I remember going to that restaurant around then and the total looks like its in line ... so if the waiterwaitress changed it to 140 I probably wouldnt catchnotice then ... There have been a few times where the total felt off but I had tossed the receipt and difference wasnt enough to investigate. Im sure I hope the amount of fraud is minimal... but maybe Im a sucker for thinking that...A while back I saw few posts about anti-fraud calculators which round updown a tip to a certain number to make it easier to catch if you tip has been messed with. that seemed like a pretty neat idea, but I dont see any iOS apps for this.Is there an easy way of tracking this? I wish credit card statements showed details... e.g. separating both total and tip, and a percentage. And I also wish you could create a notification for if a totaltip line was set beyond a certain threshold e.g. send a notification if its more than 22.5.  <response>: Could you just implement the method of making cents after youve added the tip match the tens and units of your bill? Then you can just scan down your items and see odd man out. 24.24 96.96 103.03 152.32 -- this is the one where 20 got tacked on. 63.63
