My original question was about data availability and completeness so a missing field would be relevant about the thread. However as LeSving didn’t provide information about where he is (which country) and which airfields in the area were missing during his tests, that information becomes irrelevant and unproven.
based on a few years of SkyDemon use for VFR trips around Uk, Ireland, BeNeLux, France, Germany and on my current trip to Norway:
Airspace and airport data is great. Terrain and road data was very poor in the past to the point it was useless (roads and coastlines sometimes miles away from real life) but has improved recently.
General flight planning workflow, for multiple leg trips with in-between fuel stops is great, including filing GARs and flight plans.
NOTAM workflow is poor – no easy filtering of nuisance notams, unable to hide certain NOTAMs based on some builtin nanny rules – but reasonably workable.
Weather workflow and representation is excellent.
In-flight moving map and logging is also very good.
All in all, will keep my subscription, but still a bit cautious about the terrain / map info because of the poor past performance.

For what it’s worth, I share all of Cobalt’s observations.
I seem to recall LeSving is in Norway. I have never tried Skydemon myself in any country except the UK and it seems very good to me, but I’ve never tried Easy VFR at all.
I am amazed how easy it makes the pre flight planning with all the weather, notams, and plog preparation done for you. Wish it had been the same when I did my PPL 35 years ago, the PPL Nav test (or Qualifying Cross Country as it was in my day) would be considerably easier than in the old Map, protractor, scale rule and E6 days of the last century.

Well, that hasn’t changed.

I hope this is still done using the old fashined equipment, not the fancy tablets and iphones.
As I understand it, the nav test is in addition to, and not a replacement for, the QXC

When i was instructing a couple of years ago, I taught them both the hard way (wizz wheel etc) for the theory exam and the smart way (using an app of their choice, they all went with SD) for the actual cross country flying.
For any flight, i expected them to have an accurate paper plog, lines on a paper CAA chart, and to demonstrate to me how they determined a sensible and safe flying altitude, checked NOTAMs and obtained weather information etc.
I did not care which way they did it, I actually encouraged them to use an App. When briefing, I probed more their understanding of what they saw (which side is the wind from? What happens if it is much stronger then forecast? What does this NOTAM mean? Does it affect you?), not how they got yhe information.
In flight they weren’t allowed any of the wizardry (nor did I ever take it with me when dual), though.
Before the final skill test I made sure they still knew how to get the NOTAMs from the AIS site and the weather from the met office. This was more to protect them from examiner bias than anything else.

The precision of the terrain and road data has improved dramatically and now appears to be spot on. The detail of terrain and road data has also improved, but how much seem to vary with the geographical area. In some places there has been essentially no change.

Well, not for me, and that’s the point. I was “testing” SD to see if it was something for me, an if it could do anything EasyVFR did not. I couldn’t find a single thing that SD did and EasyVFR didn’t. SD seemed more “fluent” and that was it. SD don’t even have proper maps, just some cartoonish nonsense (in my humble opinion of course). Besides, I am very happy with EasyVFR, it’s a great app, and for me to change, I have to change to something substantially better.
For the sake of completeness I will show an example. However, at the moment I don’t remember exactly which airports it were. So I took a screen dump of EasyVFR (with the ICAO map) and wrote in red fat letters the 4 airports that I think it was, maybe all 4, maybe just 1 or 2.
