New Applied Ballistics “quantum”. Who’s figured it out?

[Brandon.miller.4]

Looks like they updated the app just today including adding functionality for using DA as well as some unspecified bug fixes. I havent downloaded the update yet.

Checked for an update and couldn't find? Also looked to see if DA was available, no cigar.

By inputting a current temp and pressure wouldn’t the app be calculating for density altitude? Seems like that would be the case. I can easily get an external temp reading and my phone will supply pressure (and temp) so no internet connection needed.

Edit: Just updated app. You can manually enter your own number for density altitude if you want or leave it as calculated from temp and pressure inputs.

They added Burris reticles in the last week or so. Seems to be a work in progress, but having the CDMS seems like it will be worth the wait for the final version.

I've been messing with he new version fore a couple of weeks and had a bunch of issues at first. It was bad enough I sent in a "help" ticket and got a response the next day. Funny thing was that by the time I could get out again to mess with the app/binos a few days later almost all the bugs have gone away.
A note on the DA question was that they have found that using station pressure was better and easier than DA.
I've always used station pressure so that made me happy!
As of two days ago the app seems to do everything accurately EXCEPT upload a rifle profile to my Leica Geovid AB+ binos. Support said they are working on a fix for that too so hopefully soon.

It seems to be a work in progress....... app was released without thorough testing or something like that.

The problem with using pressure is that altitude and temp are so easy to get via analog means, but pressure isnt b/c I often dont have cell service and dont carry an enabled watch or similar. Maybe Im doing something wrong but the app will not pull a humidity or other wx info if you dont have service. A paper DA chart using absolute altitude and temp has been my go-to. The new app doesnt seem to support this, it forces you to carry and use a gizmo. If it is capable of accepting a manual DA Im all ears, just cant figure it out.

If you update it it now accepts a manual DA entry

Click on the calculator button below pressure and you can input.

Many phones now have an integrated baro sensor. My iPhone does. One of the updates AB posted added baro support for some of the Samsung phones. If yours doesn't you can do the manual entry as described above.

Divide altitude by 1000. Example 2400ft = 2.4

Subtract 2.4 from standard barometric pressure @ 29.91

= 27.51

Will get you close enough just like a DA chart

Perfect, this did it. Thanks!

I can manually enter a da in the calculator field, but it will not update the DA on the hud once I hit the “apply” button. What am I missing?

Yeah I'm not sure. It worked for me.

I hate that I can't have a range card for my 22 that uses different intervals than my centerfire rifle.

Mine can be intermittently glitchy when trying. Re-do and it applies.

Alternatively you can directly enter temp and pressure values directly in the HUD and it'll calculate DA for you.

That saves with the profile you mean?

You can change the intervals, can't take more than a few seconds.

AB support got back to me on this, as the DA calculator function is just not working on mine. Apparently they have a youtube video guide going over the new stuff. I havent checked it out yet at work, but thought I'd let folks know in case anyone else is wrestling with the update. Their advice to me was:

In your case, I would suggest:

1) Deleting the app
2) Restarting the phone
3) Reinstalling the app clean

We have a guide on the new stuff here:
