Great!

Broke out my Sextant and started playing with it again. This app makes it fun and easy to see how well you're shooting. If you use your GPS is your DR and you're not too far away or close than you know your site is accurate.

This app makes it fun and easy to use again. I don't feel like I'm cheating, but I do feel like using my Sextant again.

Wrote a bad review, developer responded asking for a chance to address the issue. After multiple emails for days there is no response from the develiper… this app does not work after upgrading to pro and paying money!!! The Developer never responds to emails. Apple gave me a refund.

Response from developer

This is certainly not what we expect from our app. If you provide us the specific details we will figure out where the issue maybe. Our latest version fixed a bug for iPads not properly handling a popup alert message. Give us a chance to address this and email support@skytip.net for a quick response.
