Highly Recommend for all Real Estate Pros
As a commercial development Project Manager, I highly recommend this app. Buy the app and its in-app purchase ($5 total if I recall), take a few minutes to review the excellent in app documentation, and set up your options.
The basic function is to put data on your image, including location, direction facing, and building elevation ("North Elevation"). Also project number and notes if you like. It will save both the annotated and clean photos.
In the app, you can also see your photo location, and direction faced, on a map.
Anyone whos ever had to photo-document site conditions or a construction progress will LOVE this app.
FYI I use it on a 6s.
