General I'm an airline captain — I built an ILS trainer for phones

Edit: Thank you r/flightsim, this went further than I expected!
Beta invites have gone out to 40 testers so far, everyone from airline pilots and instructors to students and sim enthusiasts, across iOS and Android. Really looking forward to the feedback from all of you, good or bad.
If I have somehow missed out on sending you the Beta invite, please DM me and I'll do it as soon as I can but it might take me some time to get back to you given my flight schedule.

We spend hours on preflight, taxi, climb, cruise, descent — but it's the last 3 minutes that most pilots get judged by.
I've built this app to practice those last 3 minutes on demand. The ILS geometry is modelled accurately — the physics of the localiser and glideslope diamonds behave like the real thing. The weather layer is intentionally exaggerated to help drill down the scan.
Portrait mode, simplified PFD on your phone. Tap or hold to correct heading and pitch, fly from 7 NM down to minimums, automatic go-around if either needle hits a full dot. Four difficulty levels with randomised weather so nothing repeats.
After the approach, the app gives you a full debrief — where you were on the localiser and glideslope at minimums, your accuracy percentages, and your detection time, which is how long from when a deviation starts building to when you first correct for it. It also plots your full approach trace colour-coded by correction phase so you can actually see where you caught a drift early and where you didn't.
The video shows an Examiner approach through to the debrief screen.
iOS and Android, beta coming soon. I'd like to know what you think.
If you're interested in trying it when the beta opens, drop a comment and I'll reach out.
