I’m still getting used to using this but it is intuitive and that is what I need. Thanks for making it easy

Response from developer

Thanks!!

Was the best Nav app available

Sadly I report that I prefer the previous version to the new enhanced release. Why? Because I want an app that is simple and can be used on an iPad mounted on my inner helm station and far enough away so that it’s uncomfortable to reach tiny plus and minus zoom buttons or use fingers to enlarge or reduce the zoom factor. The previous version had an optional zoom slider that could be reached on the screen’s right side and controlled easily by my right hand stabilized by the iPad’s frame. I have requested twice to have this feature added back but to no avail. Also the new version which is also Android compatible just seems to have too many marketing attractants that I should be able to turn off but cannot figure out how. As a navigation instructor this is frustrating to the max. I would love to rewrite this review to be more positive but only will if TZ-Nobeltec responds with some better news.
