Send a photo of your food and Slothwise identifies it with nutritional info. You can also send a photo of a barcode on packaged food for automatic nutritional lookup. After identification, you see the food name and macros and can confirm or tap "Wrong food" to correct (RCS) or type your correction (SMS). If the photo is unclear, you may be asked for a closer shot, better lighting, or a different angle. Photos work on both RCS and MMS.
