Co:Writer® Universal app and third-party keyboard gives students easy access to word prediction on iPad, iPad Pro, iPhone, and iPod Touch. Students simply sign in to their Co:Writer Universal accounts to write with their personal settings and vocabulary. ABOUT CO:WRITER UNIVERSAL This version is for schools with a Co:Writer Universal license only. Users without a Co:Writer Universal license must purchase the Co:Writer app. HOW DOES CO:WRITER WORK? As letters are typed, Co:Writer predicts the intended word with a selection of word suggestions using powerful grammar-smart word prediction. These suggestions can be read aloud with a swipe. Selecting the intended word places it into the writing document. For feedback while writing (and after writing) built-in text to speech can be used to read letters, words, sentences, and the entire document. 4+ MILLION TOPIC-SPECIFIC DICTIONARIES Co:Writer has access to a main prediction dictionary (that includes core words) and Topic Dictionaries (that includes topic specific words). Co:Writer can access over 4 million topic-specific dictionaries which are activated based on the writing task. A small sampling of the variety of topic dictionaries: - America's Cup - Apple II - Compare and Contrast - Dinosaurs - Grumpy Cat - History of the Peloponnesian War - Mahatma Gandhi - My Dog - Pig Latin - Rolls-Royce Silver Ghost - SpongeBob SquarePants - Tommy (album) - Wonders of the World SPELLING SUPPORT Co:Writer handles the widest range of spelling mistakes through its Flexspell™technology including phonetic spelling and inventive spelling errors (letter omissions, word ending omissions, letter reversals, etc). Examples of how Co:Writer aides with phonetic and/or inventive spelling: Before Co:Writer The blk jargon flu over the bra lfnt. R u hpy to ce me? I no hw to nor the fone. After Co:Writer The black dragon flew over the gray elephant. Are you happy to see me? I know how to answer the phone. GRAMMAR SUPPORT Co:Writer bases its prediction off of proper grammar, and uses its understanding of grammar to accurately predict words within the framework of valid sentence structures. Examples of how Co:Writer aides with grammar: Dogs are furry. (noun, verb, adj.) - When you typed d-o, you get plural noun choices Three very mangy dogs ran down the street. (adj., adv., adj., noun, verb… etc.) - After typing three, very, mangy, you get plural noun choices, then you get plural verb tenses. OTHER FEATURES - Built-in Text to Speech - Export

SnapType helps students keep up with their peers in class even when their penmanship holds them back. Students can easily complete school worksheets with the help of an iPad or iPhone. With SnapType, students can take a picture of their worksheets, or import worksheets from anywhere on their device. They can then use their iOS device keyboard to add text to these documents and print, email, or share their creations. It is the perfect solution for kids, and even adults, who struggle with their handwriting. Just read a few of our amazing testimonials: "Dear Amberlynn, Thank you so much for creating this app. You have changed the way my 12 year old son with dyspraxia functions in school. He is more independent and I cannot thank you enough. Please continue to help kids like my son. You are changing lives. Thank you." "Thank you for this ! I am going to talk to my sons teachers about this -you are a blessing ! I can honestly tell you that I have spent many hours crying inside an Hurting watching my son struggle to write pages of sentences and spelling words and other homework - to the point that I have stopped him and honestly wrote for him left handed to make it look more like a neater version of his because I could not take it anymore ! Thank you" "I just wanted to personally thank you for creating it, as this is an app that I use nearly every day with my son to do his homework. You have created an app with a simple interface, but with an incredibly powerful impact. Thank you." "It is wonderful and something so simple yet so so so important for little guys like mine who cannot write BUT is learning to type and has so much to say and SHOW." "We trialed SnapType with an 8-year old who is receiving school-based occupational therapy due to visual motor and visual perceptual issues. The biggest complaint from teachers about handwriting for this student was related to illegible answers on worksheets. The student quickly learned to take images of the worksheets with her iPad, upload them to the device and type in her answers. In addition to making her writing legible and eliminating issues with visual perceptual skills, the child's interest in the task was greatly improved, as was her pride in her work." "Thank you so much Amberlynn. What a wonderful idea and gift to those kids that struggle with dysgraphia. I have converted many a workbook page for my son. This is WONDERFUL!" "Thank you, thank you, thank you. I'm a mother of twins. My son is autistic and my daughter has cerebral palsy. They are still only 2 and a half... but I'm sure they will both need and use this. The fact that you have also made it free and are paying for it out of pocket is just the sweetest thing ever. I read about this last night and cried tears of joy. You are amazing! And I'm going to be telling everyone who will listen about you, this story, and your app. Thank you again, I truly appreciate it!!”

Verdict
The clearest difference is review sentiment: SnapType at 64% against Co's 8%. SnapType also leads on rating (4.5 vs 2.6) and update cadence (every 4 weeks vs every 4 months). Co's advantage is in-app purchases (none vs 1) and iOS requirement (10.0 vs 15.0). On price, ads and device support there is nothing between them.

Co ships an update every 4 months, SnapType every 4 weeks. The most recent releases landed on June 5, 2026 and September 18, 2026 respectively.
