Absolutely an amazing app for anyone who uses artillery in HLL. 10/10 for function and offering it for free. Let's get 1 thing clear though: only buy the premium version if you want to support/ thank the developers of the app for their work. Because it doesn't add any value or make anything easier. It could be structured 10x better, allowing you to name saved distances or customize the order other than from close to far. But instead I use it the same way I did when I had the free version.

Thank you for the review! Glad youโ€™re enjoying the app, and heard you on the premium features. I've added named saved distances and better organization based on feedback like yours. Thanks for the support! Keep the suggestions coming!

used first time yesterday and best results were 23 kills. down side is enemy tracking you down especially if team mates don't defend you if you're contributing to the game well. so in first try, is good but it won't allow Shotts in the enemy last parts of the map. especially if you are trying to help your team win the final point. so take that into account. was a decent first try

actually really like this app. only complaint is that the input feels idk, sticky or laggy? making rapid entries and corrections a little challenging. only app I've found with SPA and walking features but the data input is the only thing holding it back from a perfect HLL artillery app. solid work tho!

Yeah it's tricky I've tried to optimize. Can probably do better. I will do another pass. Thanks for the positive review!

Whatโ€™s new

New in v2.19:

โ€ข External keyboard support
Plug in a USB or Bluetooth keyboard or numpad and type distances straight
in. 0-9 enter a distance, Backspace clears the current target, "." clears
all. On SPA, "/" swaps distance and slope, "-" and "+" set the sign.

โ€ข More screen for your numbers
With a keyboard connected the on-screen keypad steps aside, so the
readouts get bigger and history shows more targets. Prefer the keypad?
Settings > On-Screen Keypad keeps it.
