Sight Calc App Reviews

Wow! What a wonderful app! If you use the US Power Squadron SR96a sight reduction form this makes the math so easy. Great job on the version 2 upgrade. So much easier to use and the results are perfect. Works perfectly. Thank you. Keep up the good work.

User friendly and accurate. Saves a lot of time

Couldn't be simpler. Great app.

A real timesaver when reducing sights using the USPS forms. Eliminates the need to find and program a scientific calculator. Well done!

As a USPS sight folder reviewer, your app has saved me hours of laborious effort. Thank very much for taking the time to make this job easier. The app works perfectly.

Great tool for sIght reductions in JN class. Thanks for this.

Great app for sight reductions. Users might also want to check out time and degree app at App Store. This sure beats using a calculator from the last century.

Simple, straightforward, works well. I use it to check sight reductions done with HO 249; it’s comforting to have an app give the same result as table lookups. Thanks.

Started using this apt last year when taking USPS "JN" to check my Law of Cosigns calculator method with the old ISO and it worked with some bugs. Upgraded to the new IOS 10 and had to workaround to get the answer. New Sight Calc 1.2 update takes care of that workaround using the new IOS 10. Stilling using it in my new class USPS "N" to recheck my LOC calculations...

I used this a lot to get through my Jr Navigation course last year with The United States Power Squadron. It was a tremendous work saver.

Slide rules and scientific calculators are not my thing. Many thanks to sight Calc for getting me through the USPS JN course!

This app is a "must" for quick and accurate solutions to the "law of cosines" ANEO

This is a great App for doing sight reductions using the law of cosines. I would give it a five star rating except it has compatibility issues with iOS 10.
