IN A WORLD WHERE D&D MEETS AUGMENTED REALITY... ——— Augmented Reality ——— AR Grimoire makes it possible to see your D&D spells on the real tabletop. Just go to any area of effect spell like "Acid Splash" or "Burning Hands" and see it in augmented reality. Get started by scanning your mini. The app will instantly visualize the casting range and the shape of the spell. Easily use gestures to move and rotate the spell around your mini. No more counting out squares on the battle map while the rest of your party is impatiently waiting. Search by "AR visualization" to see all the different types of areas of effect: cube, sphere, cone, line, and cylinder. ——— Advanced Spellbook Capabilities ——— AR Grimoire also works as a full-featured spellbook app to help you quickly cast spells and easily manage your spellbooks. Character creation is fast and simple. Just add stats necessary for spellcasting -- no need to add in everything from your character sheet. Enjoy a beautiful interface to track your spell slots, add to your spellbook, and update your prepared spells. Spells in the app have subtitles that remind you of the most important casting information: casting time, range, and damage dice / saving throw type. You only need to read the spell description if you want to dive into more detail. You can use powerful search functionality to easily filter spells down by the following categories: - Character class - Spell school - Ritual spells - Concentration spells - Saving throw types - Damage types The app also includes generated "keywords" that group spells by more abstract qualities. Currently you can choose from 8 different keywords to find the perfect spell, with more coming in the future: - Nature - Weather - Illusion - Willing - Healing - Protection - Teleport - Barrier The app includes all spells available in the System Reference Document (SRD) 5.1 via the Open Gaming License.

Stolo is an encrypted messenger that built off of Reticulum and LXMF Out of the box it is a private, end-to-end encrypted messenger: no account, no phone number, no sign-up. Your identity and your history live only on your device, and Stolo's gateway relays your messages across the internet. When you need more, the same app becomes your own network. Create a network, share one invitation, and everyone who joins is in each other's contacts, trusted, automatically. Phones link directly over Wi-Fi and cellular, and optional long-range LoRa radios carry messages where there is no signal at all. Messages to someone out of range wait and are delivered when they come back. What you can send, on or off the grid: • Messages, photos, and voice notes, end-to-end encrypted. Only the people in the conversation can read them. Not us. • Live GPS positions on a built-in offline world map. See yourself and your team with zero connectivity. Under the hood, Stolo is built on Reticulum, the open cryptographic mesh stack, and sets up in a minute with no config files. Used for backcountry trips, maritime, job sites, disaster response, and everyday group chats that should stay between the people in them. Built on privacy. Works every day, everywhere, and keeps working when nothing else does.
