Exbal or similar for phones

[fire at will]

Hi I am a uk based shooter with a 6.5 x284 and a 243 Ackley. Both are used for hunting. I am considering investing in exbal or similar to aid my long range hunting. I use a leupold 8.5x25x50 vx3 lrt scope . I also use leica rangefinding bins although these are in mtrs. I think the phone option could work well for me .

Any advice or ideas welcome !!

Regards
