Comments on Nautical Calculator for Android

★★★★★ Amazing App. I have a question about the Celestial Navigation feature... the observation point at the top of the page, is that supposed to be the DR of your first sight or your last? Thanks.

★★★★★ Discovered that both the free app and PRO app was on phone. So deleted free app. All appears to be okay now. Very pleased. Thank you. Great App.

★★★★★ Being a Navigating officer always wanted an Offline App to work through Course n Distances. ALL I CAN SAY IS THIS IS THE BEST APP related to my Profession Simply Put Lat Lon Calculate Dist and start sailing... Basically does all what U need while being offline at Sea. Keep it up Thx. They should have added an Extra Star .....👍👌👌👌👌👌

★★☆☆☆ I gave it 1 Star to alarm you. I have purchased this app long ago. I may be one of the first user to ever subscribed to your app. But after changing my phone, I can't use the full version anymore. Any thoughts,

★★☆☆☆ So here's what I think . . . But wait, first, a word from my sponsor. . . . Okay so what was I saying, oh yeah, so here's what I think. . . After another word for my sponsor, of course. . . Okay back to what I was saying, so your app is really a. . . Wait, wait a minute, wait, hold on. . . There's another word from my sponsor. . . UNINSTALLED right f'n NOW!

★★☆☆☆ Why even have it as free if you are just going to block all features unless you pay for each one?
