Just downloaded true data and starting to play with it a bit.
Offered by Sierra and Barnes bullets the program work on iPhone and android .
Seems to be straight forward so far.
I do like that one can input bullets other than Barnes and Sierra default listing .
Anyone else trying this program .

Currently running it on a old iPhone 7S . Which is offline (no plan so outside 911 no phone) and being used as a device so far the program seems to work well enough yet simple format.

How much is this TrueData app? I started to download it and it wanted me to log into my Apple account, which tells me it was going to charge me, so I backed out of it.
I have been using StrelokPro for quite a few years but they are no longer around. I still have the app on my phone so it works but I am sure as soon as I get a new phone I will lose it at that time.

In my iPhone the same, log into apple account download. Cost = free. no charge. If there is I have not been hit with it

Like I stated I just started playing with this, have yet to actually put it through it's paces for accuracy. But the base program appears to be spot on with a lot of calculators.
I like :
the ability to set certain rifles then assign certain bullets to the rifle. Input the velocities, etc. Also can create custom bullets profile, by that I mean for example Hornady bullets, you can add you favorites by getting the BC, Length etc to do calculations.

Here is where I inputted the data for CCI Standard Velocity for a Savage MK II

Range cards can be done, although they list them as Target Cards. Same thing actually.

The Range / Target cards at first was a mystery to me as when installed the apps doesn't have any.
on the home screen (the first screen shot) select the range then input the range you want to calculate the card save then you can readily view them. You can also slide the range and get your come ups.
Once the range target card has been established it goes across all the bullet choices in the screen. Which is a plus and a minus.

When spin drift is selected (under the bullet profile) you can see the program takes that into consideration in the example above I have the wind dead still for this. so it just calculates the spin of the bullet.

The program / App was just recently released by Sierria/Barnes this year, so yeah there maybe some bugs, or features that others have that this app doesn't.
Although I'm sure one can submit a suggestion to the developers.

Is this the end all be all I don't think so, but I do like the "HUD" or rather the screen.
I did get the app to gather local weather data so I can update that into the calculation provided I can get to a wifi hotspot.


Why did I stick it on a Iphone? simple I had a old one laying around collecting dust. So I figured to put it to use. I did consider get a Tracphone with a more recent android version for this, as it seems Sierria covered both OS's.

4DOF or other ballistic calculators maybe more desirable for some. I was looking for a free simple calculator so far I like this one. But Like I said may not be everyone's cup of tea.
