3 stars: I very much like the features, but the calibration never completes no matter how many times I do the figure 8. It also asks to be calibrated every single time which seems excessive. Great having true/magnetic choice and ability to sight and see horizontal. I have tried several compass apps and would like this the best by far if it would calibrate.
5 stars: Best compass app I've used. I'm a pilot, and I have a 50 ft sailboat I spend most of my time on. I'm an old fashioned guy. My sailboat has over 75 he's worth of GPS and other navigational equipment. But being an old fashioned guy I enjoy using the stars, the sun, the moon, my charts and this compass app for my navigation and it is fantastic. Navigation without GPS is quickly becoming a lost art.
5 stars: Once I hot the operational side under control it became an attractive tool to use. But it appears to me that I have to re calibrate everytime I start this app. Is that as designed There is also a challenge to understand the difference between true North and Magnetic North. When would one use which? Otherwise I like the design very much
5 stars: BEST. Simple, easy, smart. Moon and Sun data. ALL of what I want, none of what I don't. I want: calibration mode NOW, done. Vert= backside cam points to where, done. Horiz= top of phone points to where, done. Where is the moon, done. Where is the sun, done. Nothing more- done. I want it to work reliably and fast, done. PERFECTION. Thanks, y'all- for kn...
