Used by teachers, parents, and learners since 2010, Reading Machine is now available for free! This app for beginning and struggling readers is still 100% satisfaction guaranteed. If you have any technical issues with the app, or if the app does not meet your expectations for any reason, please email us so we can address your needs and strengthen our support for more readers and a better world. Email: diana@dianasharp.com or support@sharpcuriosity.com Reading Machine helps readers learn new words by seeing and hearing how the letters and sounds in a word go together. The app is perfect for times when readers can’t or don’t want to ask someone else for help on unfamiliar words. Like a personal reading tutor, the app guides readers into figuring out a new word based on the word’s letters and sounds. Readers can use the app while they read traditional books or other printed material. They can also use the app alongside e-books, websites, and other digital material on the iPad. The app is a fun addition to parent-child reading time, and it also works well for older readers who do not like to ask for help on words when they read independently. Developing readers of any age can gain self-confidence as they figure out new words on their own with the app’s support. Videos of how the app works are available at www.sharpcuriosity.com. Created by a parent, learning scientist, and reading researcher, the app’s underlying dictionary is powered by a real human voice with support for over 5,000 words, plus a text-to-speech engine for pronouncing all other words. As readers advance from simple to more complex words, the app dictionary provides tailored decoding support for each word, ranging from individual phonemes and letters, to multi-letter sounds, syllables, prefixes, suffixes, root words, and whole words within compound words. The app also includes suggestions for parents about fun books to get at the library or bookstore to match readers’ interests and skill levels. • The Reading Machine is like a secret decoder ring for unlocking printed words. Use it paired with real books – books you already own or books you’ve borrowed from the public library. Or use it on the iPad alongside e-books or web pages. • Great for early or struggling readers. • Lets you have more fun reading with your child because your child can use the Reading Machine to figure out words instead of having to ask you for help. • Best for children who already know the sounds that go with each letter and can read some words, but still need help reading sentences and books. • Comes with full decoding and phonics support for all the words in over 125 well-loved early reader titles. Older readers can even use the app with the first chapter of Harry Potter. • The app provides lists of suggested titles (“Book Sets”) for readers with different interests and skill levels. This is a great guide for finding books your reader will enjoy. These books are easy to find for free at your public library. Or head to your favorite bookstore. • All the words in over 125 books, listed in the Book Sets, have phonics support provided by the app, with clear pronunciation recorded by a natural, human voice. • For any word not in the app’s dictionary, readers can hear the whole word pronunciation with text-to-speech voice. So they are never stuck on any word. • Among the words that have phonics and decoding support are the 300 most frequent words in the English language, which cover 65% of all English reading material. Many of these words are often called “sight words.” • When new Book Sets and new words are available for the app, they can be downloaded for free from within the app. For more info and videos, see http://www.sharpcuriosity.com

Verdict
The clearest difference is rating: TurboWords Spelling at 4.6 against Reading Machine's 3.6. TurboWords Spelling also leads on ratings volume (1.8K vs 13) and update cadence (every 4 months vs every 14 months). Reading Machine's advantage is in-app purchases (none vs 3) and iOS requirement (8.0 vs 15.6). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. TurboWords Spelling sells 3 one-off in-app purchases. Reading Machine asks for nothing beyond the download.
TurboWords Spelling holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: TurboWords Spelling has 1.8K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 75% of Reading Machine's written reviews are positive against 69% of TurboWords Spelling's, so the app with the better star average is not the one people write more warmly about.
Reading Machine ships an update every 14 months, TurboWords Spelling every 4 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
