Air Navigation Free App Reviews

Works really well and is accurate. Cant beat it or the "price". Thank you for doing such a great job.

Note that there is a manual on the developers website (for the Pro version) that addresses most of the critical comments in other reviews. No stability issues for me on iPhone 4. Not sure about currency of database, but it has good info for the airports near me except for comm frequencies for small fields (not inaccurate, just missing sometimes). There is a bug with opening the list of navaids, but re-opening the list several times will get it to populate (reported long ago but not corrected). Overall a very good app. The free version makes a possible backup to a panel mount GPS. Could be used as simple primary GPS for VFR as a supplement to FAA sectionals. The HSI view is very nice. Setting the CDI needle to align with the runway heading provides excellent orientation when approaching and following a traffic pattern.

Nice tool but after 5 attempts to use while flying a Cessna 172, will not capture GPS or any nav freqs. Using on I-phone 4.

I have been unable to find any good HSI app except this one. Id pay for it if it had a heading bug, and the ability to make a basic multi point flight plan or load the fixes on a US approach plate. The developer has a full featured planing app but I already pay for and use Foreflight so I dont need that. However, it lacks an HSI. If the developer reads this, Id push this app to my students if those few items were added, even pay for it.

The app did well on its first download- when it locked up and I reloaded it, it refuses to function. Cant get beyond the initial page. I liked it when it worked- bummer.
