David R is on the money with the complexity involved, but hey it’s a good start

The thing is, there are two problems with knowing which blessing to say. One is the words of the blessing, which this would help for. The other is knowing what to say on which food, which can get really complicated (there are entire books on the subject, not to mention “Beracha Bees” in Jewish day schools to help students learn).

For instance, not all fruit is haEtz (take melon, which is grown in the ground and is haAdama). And, when does something move from haAdama (potatoes, clearly from the ground) to sheHaKol (potato chips, which aren’t quite as recognizable as from the ground). Cereals can be either haAdamah (corn flakes), sheHaKol (corn chex), or Mezonot (cheerios). And there are Crispix, which (no kidding!) most books will say you need to say two blessings on, Adamah for the corn side and SheHaKol for the rice side (why rice is sheHaKol is just another example!).

You can check out this link for a long list of foods (and I assure you there are disagreements over some of them).
