I haven't seen much of anything about the DM100. So I'm gonna give yall what I did. I saw a tiktok about a guy watching YouTube on a smart watch. Gave me an idea. I went to Amazon and found a different smart watch with a huge screen. https://a.co/d/d6x0rzM is the link to what i bought. This thing has android 7.1 I thought if you could watch YouTube, and play Call of Duty, why can't I run a ballistics calculator? So I watched some YouTube and did some downloading. I started with downloading and installing nova launcher 6.2.19 This was a process. I tried a few different calculator apps and didn't have a ton of luck. I ended up finding strelok pro version 6.2.9 and boom. Digital dope card on my wrist. I have 10yds out to 1000 yrds of dope. I'll gather up a few links to where I got the downloads. And post them asap.
