1. Genius Scan What it does: Puts a document scanner in your pocket. Enables you to use your phone’s camera to take a picture of a document, then email it to anyone in PDF or JPEG format.Why it’s useful: Many real estate agents now use digital document signature software which allow you to sign with a click and, more importantly, without faxing documents back and forth. But some don’t - and some mortgage lenders will simply not accept anything but a copy or scan of your ‘wet ink’ signature. Throughout your transaction, you might find yourself needing to scan and email your contract documents with your original signature, a copy of your deposit check, new payroll check stubs as you receive them, your driver’s license, a gift letter from your Auntie Grace or any of a number of other documents you’ll need to get to your agent or mortgage pro across town - or across the country. Having the ability to scan documents and checks and email them right from your phone can save you a lot of time and hassle - not to mention gas and cash.

The Dictionary includes over 3,000 real estate terms, charts and graphs. You can save your searches and email terms to others. Your phone does not have to be connected to the Internet to use the Dictionary, which can be useful if you need to look up a term on an inspection or appraisal report while you’re in a home or office where you don’t have a great connection.Why it’s useful:  I can guarantee few things in life, but one thing I do feel comfortable assuring you is that home buying will expose you to terms you have never heard before. You need to know what the terms used in your inspection, disclosure, contract and loan documents mean, and sometimes looking them up is the best way to do that.Works with: iOS and AndroidPrice: $1.99 (iOS) and 99 cents (Android)3.
