TeaCodex is an English tea library stored on your device. Browse a built-in catalog of teas with photographs kept inside the app. Search by name, origin, or cultivar, and open any entry for processing, flavor, brewing, and storage. Add your own teas and choose a picture from your photo library. The picture is copied onto this device. Export a JSON file that includes those pictures, or import a TeaCodex JSON file. If an imported picture is only a web address, TeaCodex downloads it once and then keeps the file locally. Your catalog, notes, and pictures stay on this device.
