Phonics Genius is a FREE app with over 6,000 words grouped into 200+ categories. There is a learning mode and a quiz mode. In the learning mode, words are presented and pronounced one at a time. The sound that is being emphasized is in red. In the quiz mode, kids have to choose the correct word from a list that can be set to include 2 – 6 words. The app permits you to pronounce/record the words in your own voice – a great option for kids working on articulation. The app also permits you to add/delete cards.You can also combine categories.

So, here are some things to consider:

The “ing” and “ed” sounds have 3 categories based on what happens to the base word when the “ing”  or “ed” is added. Does your lesson focus on the sound in the words or the structure of the words? If it’s about structure, use all 3 lists and have kids discover the rule. 🙂 Please note – skiing should be in “ing 2” since the root does not change.

Some of the categories contain more than one syllable – ary, ation, etion, ician, ible, ical, ician, ity, etc.

Some sounds (such as ff, ck, ll) are found in multiple categories only because they occupy different positions in the words. You can combine these categories if you wish.

The category “j sound of g” contains 3 words (hedgehog, gadget, garage) that also have the hard sound of g. I would delete these 3 words to avoid confusion.

The “h hat” category is labeled as “g beginning”.

The “o cvc” category has bow as the example card but the cards in the stack do follow the rule. Bow should be in the one of the “ow” categories depending on its pronunciation.

There are 2 “oi” categories – oi & oid. I would combine them since the sound is the same. I would also delete tortoise.

If you are trying to generate a list of words with specific sounds, this app could be a resource. I did not go through all 6000+ words in this app – there are probably additional tweaks that I would make depending on how I was going to use it. But, because it is customizable, you can add, delete, and combine categories to make this app work for you!
