### 5/5 — Works well for me.

*2026-03-30, version 4.2.3*

Been using this for years now and comparing it to another super calculator I use.  For the practical application I use Bullet drop. I shoot competitions from 200-1000yds known distance.  My chronograph speeds, speed at the target, and bullet drop are all pretty good.  To site in shots……I’m in.

### 5/5 — Excellent app

*2026-03-18, version 4.2.3*

I have no notes on how to improve this app. Maybe could use metric as an option

### 5/5 — Perfect for me

*2025-01-16, version 4.2.2*

Straightforward to use but works fine producing same results as others I’ve tried.

### 5/5 — It’s been updated!

*2024-11-15, version 4.2.2*

Just letting everyone know the app creator updated this after a very long hiatus. You can now delete entries, including the ones that were already loaded in the download. This is the best app and easiest to use.

### 5/5 — Finally Updated!!!

*2024-04-20, version 4.2.0*

App was awesome until it was left unattended and developed bugs as iOS updated.  Thx for fixing!!!

### 5/5 — Love it

*2023-12-10, version 4.1.1*

This is my new favorite no nonsense BC.

### 5/5 — Everything you need

*2023-09-10, version 4.1.1*

Perfect for use on the range, simple easy to use and as accurate as you would ever need. I love that you can adjust increments so one app is good for air rifles through to 50 cal

Thanks for fixing the delete bug and keeping the app add free. It gets 5 stars from me now and a coffee for the developer.

### 5/5 — Finally!!! :)

*2023-08-23, version 4.1.1*

Thank you! Officially the best and most user friendly app now! The patch dropped today so now we can delete saved data entries ^^ the only thing that would send this app above and beyond is barrel twist and barre length. Thank you to the people behind the scenes who fixed the app. You are all amazing!!

### 4/5 — Best One, All Things Considered

*2023-07-23, version 4.1.0*

Pros-
-Its simple. Has just what you need without being overcomplicated
-Its free.  There is a tip jar (which I used) but its voluntary
-No data mining. Data policy is no collection
-Obvious small developer. Its clear that this was made by a shooter for shooters, not developed to extract money. Thank you!

Cons- 
-Only one, limited support. I get it. Anyone who uses this app should get it. It was a gift to us more than a transaction. This guy undoubtedly has a regular job and this was a side hobby. He may well have lost interest, especially after reading some negative reviews.  BUT…if he took a few minutes to update his email address and fix the ‘setup delete’ bug, all of his users would be very grateful Im sure. And retract negative comments, right guys? (Hint)  Sifting through samples and mistakes is pretty annoying. 

Summary. 
Its not perfect but it has what I wanted and I like it.  It just needs a few hours of polish to be perfect.  I cant see using a subscription app when this is available and easier to use.  And I always appreciate apps that aren’t corpo data miners or expensive subscription based.

### 5/5 — Great ballistic app

*2023-07-05, version 4.1.0*

This is my favorite app for load development.  It’s very user friendly and provides all the information I need for the multiple calibers I load.
