Cons
Con Nativescript + Angular apps for Android tend to have long startup times.
It's very difficult to have acceptable startup times with NS+Angular in Android. It's not uncommon to see apps taking 6 sec or more to start AFTER having been optimized with Webpack (mandatory!). The same app in iOS takes only 2-3 sec. Also, this seems to happen only with the NS+Angular flavour. People using plain NS (without Angular) don't seem to have the issue.
Con Developed by a single person
Statistically, apps being developed by a single person can be gone without warning.
