Simplex Spelling improves English spelling and reading skills in a fun and interactive way by combining a unique "reverse phonics" approach with contextually relevant spelling rules that explain why words are spelled in a particular manner. It works like a personal spelling coach with every word.

Simplex Spelling HD contains over 260 English sight words including all of the words from the Dolch word lists. The Dolch word lists consist of 50-75% of all the words used in children's literature. Learning these high frequency words will help the student to establish a strong base foundation in spelling and reading fluency and will build their confidence.

Rather than using flash cards, Simplex Spelling enables the student to build each word phonetically using the built in "reverse phonics" hint system that teaches both phonics and phonemic awareness. Students gain necessary skills to become both effective readers and spellers, rather than relying on the sheer memorization of words. The informative spelling rule hint feature also explains why words are spelled in a particular manner.

Research studies have found that the best way to teach reading is through phonics and phonemic awareness.[1] In addition, great spellers almost invariably make great readers. However great readers are not always good spellers. So learning to read through the synthetic phonics spelling approach in Simplex Spelling will give your student the best chance to establish both spelling and reading fluency.

Phonics has also been demonstrated to be a much more effective method of teaching reading for students with dyslexia than the whole word approach as it teaches left to right reading of sounds which research shows is in line with the way the brain works.

Many people mistakenly believe that sight words cannot be learned through a phonics approach, but the fact is that the vast majority of sight words can be sounded out properly using a full synthetic phonics approach such as the one used in Simplex Spelling.

Simplex Spelling's unique, immediate letter by letter feedback system is designed with clues and hints that will enable every student to spell each word successfully. It is great tool to have for kids learning to spell and read, remedial students, those with dyslexia and special needs, or those learning English as a second language.

Simplex Spelling is also equipped with an automatic progress tracking system that enables you to see at a glance words that have been mastered and words that require further practice.

Simplex Spelling enhances understanding in a variety of students as it appeals to audio, visual and tactile learners.

What others are saying about Simplex Spelling HD

Applicable2U the review is also featured on I Education Apps Review (

"If you happen to have a young child just learning or is in need of support with their sight words, then Simplex Spelling HD is the way to go!!! Its name says it all, it's very simplex. Applicable2U has explored a number of spelling applications, and this is the best one yet."
"While experiencing this application, Applicable2U felt like we are a part of an interactive spelling bee."
"Currently, it is selling in your iTunes library for $6.99. Some might say that it is a lot of money, but the academic results that you will see in your student or child will be amazing."
"Simplex Spelling uses a reverse phonics approach, but it is certainly not reverse in its thinking as it heads in the right direction of teaching our young population to spell towards the future of reading."
"Whether you have a kindergartener or late elementary aged student(s) or child(ren), Simplex Spelling HD is applicable to you. Start your download today by clicking here."

The iPhone Mom

'If "tremendous" was a Dolch sight word then you would find it in Simplex Spelling HD and it would be right at home because this is a tremendous spelling app!'
"The app begins with one of the best help features that I've ever seen in an educational app."
"I was absolutely pleased with Simplex Spelling HD. Everything about the app feels like it's been done in such a way as to build confidence and spelling success. Bravo!"


"Simplex Spelling HD uses incredibly rich, educationally sound, and powerful tools to teach high frequency words. With 220 words included and the wealth of tracking tools it provides, it is well worth the price."
"The method used – dictation followed by tapping and dragging of letters into the correct order within a word – is incredibly effective at teaching spelling and the combination of the easily accessed phonics hints makes Simplex Spelling a very powerful tool for direct instruction. It is very easy for children to learn directly from the app without parental input beyond assigning a spelling list for each session or asking them to review a certain list."
"The use of phonics is both intuitive and a bit playful – it is fun for my daughter to be able to explore the different potential options for a certain sound using the hints feature."

Mobile iEducator the review is also featured on I Education Apps Review (

"Simplex Spelling HD is incredibly easy to use."
"But what is great about Simplex Spelling HD is that the phonogram for each letter combination that makes that sound, single or multiple letters, is provided for each word."

"Multiple users can be added to the app making it perfect for a household or classroom that has fewer iPads than children."

"In addition to learning the sight words, which increases reading ability, students are supported with positive feedback (whether they used the hint button or not) helping to build confidence as well. Simplex Spelling HD is an excellent tool to support literacy and help young readers grow!"

Teachers With Apps

"Lisa's goal is to take academically challenging work and present it in a clear and concise manner. Simplex Spelling does just that, using the original 220 Dolch Sight Words. This app provides leveled lists to practice spelling skills with complete ease."
"Simplex Spelling enables the student to build each word phonetically using the built in "reverse phonics" hint system"

Technology in (Spl) Education

"Simplex Spelling – If you have Spelling Goals in your IEP, then this [is] the app for you."
"Simplex Spelling – The name says Spelling but we found it is more than that. It is not only a great spelling app but also teaches the word usage/phonics and more"
"Wonderful app…great for kindergarten and up! Easy to use, great record keeping and the sentences spoken for the word to be spelled are clear and well written."

Ms. Amato - Teacher NYC

"The Simplex Spelling HD application for sight words is wonderful. I work with students with autism and my students absolutely love it. It is an amazing way to learn the basic sight words. My students were motivated to keep spelling the words. My students loved when the program said and they saw good job, excellent, mastered go on the screen, it was a positive reinforcement. I also love that this programs gives phonic hints that allow the students to press when they need help [to] remember what letter is next and it gives you the letter and its sound. This is a wonderful concept. My students have increased their spelling correctly by fifty percent. It also helped to reinforce my classroom letters of saying the word and sounding it out to spell it. My students created beautiful writing pieces from a read aloud and spelled all of the words in their sentences correctly. I would recommend this application to all parents and educators. It would be a great use for anyone to utilize with both disabled and non-disabled students/children. Thank you for creating this wonderful application. This is an essential I-Pad application for our early learners and I would get it as soon as you could. Thank you to Simplex Spelling for their wonderful application."

A4cwsn - Tobi Price, assistant school principal

"The simplex apps are designed to help your kids learn how to spell. They feature lessons that let them work through at their own pace."
"This app has a few features that as a parent and educator I feel are a must have. The first is that there are no in app purchases, no links to social media or pop up ads. Next, as a teacher, I like that you can set up to 40 different users in the app & it will track their progress. So everyone in your class can use one iPad and work on the app."
"I like the way you can go through the word lists and see which ones are going to be tested. You can start a student with an easy or difficult lesson. You could also use the app to meet a student's specific spelling needs."

The iMum (Best Spelling Apps On The Market)

"Overall, I really like the Simplex Spelling apps and think they are the best on the market at teaching your child how to spell in English."
"where the Simplex Spelling apps excel is teaching your child how to spell. I really like how individualized the hint system is – you can choose to have no hint, or just hints for individual sounds, and instead of just telling them the letter that is missing, it teaches them what could make that sound. I also like that if the child gets the right letters but in the wrong order, the blue colored tiles let them know that, instead of just labeling it as wrong."

Andrew K from Hub Pages in his "Review of the Best Kids Educational iPhone Apps"

"Simplex Spelling HD is one of the best educational apps for kids"
"I have decided to start the list with this amazing iPhone application. It is intended to improve spelling skills of kids. This application expands vocabulary of kids significantly and provides an easy and interesting way to learn new words. So, playing this iPhone app kids will improve their vocabulary and learn how to spell words correctly. Simply know that this great iPhone app can bring a lot of advantages to child development of your kids."
