Honestly, I'd rather get lost in the middle of Montana than rely on this compass to guide me anywhere. Whoever made this app should consider letting a blind person revamp this app, maybe it'll actually be effective. I read the directions and everything, it's just the most complicated compass you could possibly create. If you're lost and you have an iPhone, forget this app and just refer to your maps app to get you where you need to go!

So many negative reviews, ouch... Here’s my take: this is free, and it works. The gray “shadow” moves around the dial VERY slowly throughout the day, so don’t expect this app to ‘do’ something active, it doesn’t. As explained, orient your finger’s sun shadow over the gray shadow on the screen, and you will see roughly accurate cardinal headings (N,S,E,W) but not exact degrees. In a pinch, this will get you un-lost if needed. Works great on my iWatch gen 4 too. No need for cell or WiFi connection. Thanks, app maker!!

It is an experimental intelligence measurement system. If the 1 stars vs the 4-5 stars are indeed an measurement of those who simply cannot comprehend instructions, or choose not to, it is a sad commentary on the decline of our societies critical thinking skills. It would be interesting to know if the author is indeed in some psychological expermental field and/or a student of same. The app is great though; I actually used it for real once and the measurement was accurate enough for me to get where I had intended.

I think it’s great if you read the description. It can double as a sundial. Great tool for teaching kids how the earth works, doesn’t work so great on teaching adults to read. Disclaimer: doesn’t work very well on cloudy days... I can’t figure out why?Really... all you haters!
