I also use several different apps. I find that when there is much difference the issue has always been a "smart" phone screen to enter data or my bi-focals! Good luck in resolving the problem but the final test is always at the target.

Post pics from each app showing the important pages and let's figure it out.

Could be the 'scope height' values are set differently as well. Shows a 6 to 7 cm poi difference running fast numbers for 0.5" of scope height variation at 600
For a 6 BR neither sounds close to correct for 600 yards....just going off of 6.5 data ....it's half that number...that 6 would be falling like a manhole cover!

My 21" barreled 243 with 103gr eldx at 3130 shows 9.5 moa at 600 yds and that is with strelok

The mathematics for most ballistic calculators are the same. The differences are almost always a difference in inputs, usually unintentional.
I've run the same data through JBM, Applied Ballistics, Hornady standard and 4DOF, Berger which is a simple version of Applied Ballistics, Shooters and others. My findings have always been the difference was my input error.
Standard Atmosphere is the mean of urban areas across the US it is not always the same from calculator to calculator. Check that as well if you are not setting them for your location.

@Nuclear Worker please post up your load data and we can run it through our app and see what we are getting. Im sure its a simple fix when we find the error. Dont be ashamed, its the fun part about Long range shooting and all of us are weird and like to trouble shoot or we would just play golf of something...LOL
bullet, MV are the 2 big factors and then we can make some calculations.
for a similar example my 6x45 with an 80gr speer SP(flat base) @ 2800fps MV is 16.5moa solution for 600yds

Best most fun is to go zero each at 100 then blackout to different ranges and shoot and measure.....the heck with the app....that's for after....
I don't know the fps coming from my 223ar....but with the scope I can put it on 7x hold the heavy post and blast things at 500yds......

Okay I hope the pictures will help? Just for clarification she is shooting Factory Lapua 105 grain scenars. Her barrel is 18.5 inches long. The mv was taken using a magneto speed 3. I have a Garmin chronograph now when I get a chance I will reconfirm. Otherwise it's a MPA chassis Big Horn action , cf Bartlein, Trigger Tech Diamond trigger, Trijicon 10 mile scope.
