What is Rand/0
Rand/0 The Pocket Prophet is a smart e-ink device you can carry with you.
It is not a serious productivity tool. It is more like a small oracle slip in your pocket. When you get stuck on small questions like “what should I eat today,” “should I go out,” or “should I do this first,” shake it and let the little screen say something first.
The Book of Answers, dice, coin flip, random numbers, and quick decisions can all give you a lightweight result. It does not make the decision for you; it simply helps break the pause and gives you a direction to keep moving.
What it can do
- Random decisions: Book of Answers, dice roll, coin flip, random numbers, and quick decisions;
- Daily companion: personality guide, wooden fish, custom lock screen, and other lightweight content;
- Daily hints: daily prompts, lucky colors, do/don't suggestions, and daily status;
- Calendar and time: always-on e-ink display to reduce the need to pick up your phone;
- Practical tools: Bluetooth remote control and NFC card support.
