The service is still in beta, so some planned features are missing.
https://pixelbrushio.itch.io/battlemappBattleMapp is free and runs in the browser and there are Patreon-only features: hero characters, an extensive list of props, premade maps, token avatars and much more. Version 1.0 of BattleMapp (in development) will have save/load functionality, map exporting features and much more, and will be free (including all updates) to Patreon supporters, always.
