It is adequate for helping to keep track of what you already learned. It gives recipes for things like enchanting which is nice but does not give recipes for provisioning and thats what I bought it for. In defense of the app, it did state that it only tracked what you learned and not the ingredients so my fault for not reading. I wish the developer would add the ingredients so this doesnt seem like such a bare bones app......in relation to provisioning anyway.
