A lot of work for just a single person with a day job, but it's finally ready, and I'm pleased: https://creativevirgo.itch.io/gamers-dice-free. I hope you guys like it. Feedback can be included in the upcoming Gamer's Dice Plus, which will cost a little bit.
For table-top gamers who leave home without their dice, this app has got you covered. The physics and graphics look so believable. We hope you will enjoy.
