This app can use the inverse square law to calculate boundaries using any amount of time, and shielding for 3 different isotopes. It can calculate more accurate UTT readings when taken on hot pipe, and it can do known to blown calculations for you. This app is still being developed, and many more calculations are to come.

However if you just performed UT a 900 degree pipe and need to do a temp conversion, or just shot a butt load of profiles and need to calculate known to blown quickly, or someone just walked into your barricade and you need to know how much they picked up, this is the app for you!
