Make up your own, better mnemonics.

Amateurishly conceived by someone not smart enough to pull it off. The relation between hiragana character and mnemonic image is often very contrived and weak, depending on making up big details and ignoring others, and often with overlaps—two are based on the number 3, two are magicians pulling a rabbit from a hat, etc. The relation between that image and its mnemonic phrase is often backward, especially the ones with names—its (sort of) easy to go from something like "Sam is always right" to a picture of a face looking right, but in the other direction—which is the direction needed in actual use—how is it apparent the face should be named "Sam"? But worst of all, the phonetic link often goes by spelling, not actual sound—e.g. the hiragana character for "sa" is not even actually pronounced like the name Sam. Terrible. Also, this app isnt particularly well programmed, with low attention to details like restoring state or making slow animations interruptible.
