I use Fatsecret, so I can calculate my protein and calories. I tend to travel, so there are barcodes from many countries. And irrespective of the country, the app fails 20% of the barcodes which is the only annoyance on the app (I workaround 'searching' for something similar - I don't care to record perfectly the mg of protein, but ballpark is good enough).
I wonder (not really) how you will find & complete the library (no need to explain) of barcodes and for how many countries/continents.
Some people (e.g. me) don't care to see (e.g.) the "mTOR Activation" but care for Protein, Calories, Electrolytes, etc. So perhaps make it (if you haven't already) customizable, so that people can disable/deactive the 100 metrics, and keep the few they really care for.
