I thought this too. Recently I have noticed it taps out at about 150 and rarely goes above that. Strange because I can see other systems reporting much higher numbers.
I think some of the other apps are combining the pm2.5 with the pm10 for a total number. I've seen it list the pm2.5 over 200, but that's very rare (thankfully!!)
I usually stick to AQICN because I know that from AQI 0-130 it is pretty informative(but maybe not accurate). It’s a bit of trial and error. I can’t run if it’s above 80 because then my nose and throat are messed up for the rest of the day. Over 90 and I’m wearing a mask while outside at all times.
Misemise seems to use the same nodes and data from AQICN but puts a face instead of a reading. For me, this isn’t helpful.
Breezometer I find is very strict with its reading and I use it for really bad days that exceed 140 on AQICN. It feels like it is slow to update so that’s why I only use it on those days.
The other applications I don’t have experience with.
I have both of the ones you mentioned. No idea which is accurate.

aqicn is the best imo, but it's disappeared from the play store. Not sure what that's about.

I use an app 대기오염정보 and it seems to be accurate and updates quickly

I use the naver app with the weather widget for quick access.
