Hobby Codex is a mobile app for miniature painters. It keeps your collection, paints, color schemes, projects, and painting journal in one place. Once boxes start piling up, notes get scattered, and you can no longer remember which paints or steps were planned, it becomes hard to keep track. Hobby Codex helps you follow a miniature from the box to the finished model. Start by scanning a box Scan its barcode, or search by name, to find its contents and add its miniatures to your collection in a few taps. No need to enter every reference one by one. The catalogue also lets you browse available factions and boxes. This feature is available with a subscription. You can also add a miniature manually, whether it comes from a box that is not in the catalogue or is a custom reference. Organize your collection Track the miniatures you own or want to buy, along with their assembly and painting progress. Add your own photos, notes, and details to keep a useful record of every model. Plan your painting - create color schemes; - break a miniature down into parts and painting steps; - keep track of the paints and techniques you use; - see which pots are missing from your inventory. Move your projects forward Group related miniatures into projects or campaigns. Track their progress and keep a clear view of what remains to be done. Keep a record of your sessions The journal records your painting sessions: time spent, miniatures worked on, calendar, and progress over time. Pick up where you left off without having to reconstruct your plans. Your collection stays on your device by default. If you create an account, you can choose to back up your data and photos to the cloud and restore them on another device. Hobby Codex is available in French and English, with no ads. Catalogue subscription Tracking features are free. Access to the box catalogue requires an account and a Hobby Codex Catalogue subscription, monthly or yearly, that renews automatically.
