I really like app much better than Xavion. Xavion has been tweaked to death and also wants $9.95 per month to keep it working.

Update after a year of use; I absolutely love this app. I have it running on a mini iPad mounted on the post between my windscreen and the pilot’s window. Both safety and convenience are enhanced by it use. As soon as I get close enough to my landing airport I will activate that airport and then go back to the "Nearest Airport" (Just in case). It will tell you the pattern altitude and also give you the time to start your decent at whatever decent rate you have programmed into it. It has never given any trouble at all and works well (mounted in that window) with only the iPad’s GPS. One of my more useful aviation apps. Update after over 100 hours airtime with this app; NRST has worked perfect and never given a minute of problems. I especially like the “TOD” feature that tells me when it’s time to start my decent. I normally fly from 6,000 to 9,000 feet and like not having to calculate my time to descend. I’ve noticed a couple of 1 Star ratings and do not have a clue as to why. Great aviation app.

Not terrible but you can get the same features in a better or similar interface elsewhere. And don't pay the $17.99 fee. The watch part is cool but still not worth the price. "Free" trial is bs, sorry.

And to me a lot of the reviews look more like fake gamers than pilots.

This is a great and very useful app to have available in the cockpit.

Bought this app last week and did a cross country flight. Compared the reading to my Garmin 430W and were the same. Great app for situational awareness and gives TOD to the airports. I had a question and emailed the developer and was back to me very quick.

If you fly cross country and not familiar with all the location of the airports this is something you should have.

I've used this app on two flights so far and I love the TOD feature. If you're a pilot you must go buy the watch and download this app!!!

Very useful for avoiding constant mental math. Does what it says.

Would be nice to see a configurable audio "500 ft" call-out. (Or other configureable altitude)

Toonsy was very responsive. The biggest issue was that the watch software needed to be updated to 2.0 (nrst simply doesn't work on older versions). The iPad "freeze" was finally fixed with a hard reboot.

Loaded NRST on iPad and iPhone. Works on iPhone, but not on iPad (frozen- and can't change screen). Doesn't seem to have I watch support as advertised. Sent email to generic address and awaiting response. I think I bought too soon.

Used it the first time today - it did everything it was supposed to do. The App was exactly what I was looking for. The bonus is it is simple, uncluttered, easy to use, functional, with a perfect display. It is simply an elegant product.

Very helpful to any pilot. TOD and nearest airport could be a lifesaver. For this price and what it could provide in an emergency, PRICELESS! Have this capability on my glass panel, but I am incessantly desiring 2nd or 3rd levels of redundancy. Highly recommend

I installed app and was quite surprised my nearest airport it suggested has been closed for years , not a good start NRST. I do not see anyway to update the database.

This is a great idea for an app but it's "buggy" on my IPad mini which I use for flying. I will update my review if you can work on the Ipad issues. (Airports disappear on left side, does not show runway or direction to airport on main screen which makes this useable on my IPad mini).
