This Measurement Application doesn’t need other notes or scientific calculator for measuring levels of something or EDM(Electric Distance Measurement device) measurement. Function of surveying computer . 41 languages are available(English, Arabic, Bengali, Bulgarian, Catalan, Croatian, Czech, Danish, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Low German, Malay, Norwegian Bokmål, Persian, Polish, Portuguese, Romanian, Russian, Simplified Chinese, Slovak, Spanish, Swahili, Swedish, Thai, Traditional Chinese, Turkish, Ukrainian, Urdu, Vietnamese,Belarusian,Serbian,Srpski,Khmer) . Sound and operational(+-) support are available when there is the keypad input. . When you enter a value of level, the ground level is displayed immediately . If you enter the final height, the difference between the ground height and the final height is displayed automatically. .The values of Level Measurement can be stored in the personal terminal and they can be saved as Excel file. . Automatic numbering of station numbers in leveling (When entering the enter key) . Excel file can be imported and inputted when inputting coordinate value (long touch) .You can get the distance and azimuth( Degree, Gradian, Radian) of two coordinates. .If you know the coordinates of one point and azimuth and distance, you can calculate the coordinates of different points. .If you know the coordinates of two points, you can get all coordinates on a straight line between two points. .If you know the coordinates of two points, you can easily obtain the rectangular coordinates between two points. .The coordinates of the center of two coordinates can be obtained. .If you know the coordinates of the two points, you can know the coordinates of the point that you do not know as a resection. . The coordinates of the intersection of two straight lines can be obtained . You can get the Coordinates(x,y,z) of Slope . All the coordinates of a straight line can be extracted and used as desired intervals. . All the coordinates of a circle line can be extracted and used as desired intervals. . All the coordinates of a clothoid line can be extracted and used at desired intervals. . Display of X(N), Y(E), Z and X(E), Y(N), Z . Leveling data can be shared

Verdict
The clearest difference is price: TriCalc at Free against Good Survey's $1.99. Good Survey's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence, device support and iOS requirement there is nothing between them.
