Scientifically validated as a highly effective approach to improving spelling skills through our phonics approach, a published study revealed that students demonstrated an average spelling improvement of 1.9 grades among children in a classroom setting who regularly used Simplex Spelling over a 18 week period. The largest student improvement observed over the same time period was 4.4 grade levels as assessed by administering the Schonell Spelling Test.

Simplex Spelling Phonics 1 teaches a full year of spelling curriculum with over 450 high frequency words divided into 42 lists that are organized by spelling patterns and difficulty levels. Each of the 42 lists comes with a lesson that teaches one of the basic building blocks of spelling in the English language. These basic building blocks include the different phonograms, sounds, and spelling rules.

Our spelling lists focus on some of the highest frequency words in the English language to help students establish a base foundation of literacy and confidence with spelling and reading.

Students learn a new concept for each lesson building on the skills learned from previous lessons. Simplex Spelling Phonics 1 guides the student and acts as a personal spelling coach with every word, while teaching "how to spell" English words.

Memorization may be sufficient to pass a spelling test, but it often does not transfer into good long term reading and spelling skills. Our goal with Simplex Spelling Phonics 1 is to not only teach a list of words, but to teach students “how to spell” these words, thus building long term skills that can be used for over 84% of the words in the English language that follow phonetic patterns.

Many studies show that students who learn to read through phonics have a higher level of literacy than students who learn to read by using flash cards and the whole word approach. Also, that not all readers are good spellers, but almost all good spellers are also good readers. This is why Simplex Spelling's comprehensive unique phonics approach to spelling really works to create both better spellers and better readers.

Note: Now supports both North American and British accents.

Note: You can not create your own spelling lists.

Working odd

My son just finished and he got Flawless on 13 words but when we finished it said he missed a whole bunch of words. So what is it, that really messes with him. So frustrating.

sam maz ,

great app

It is very educational with great style.I strongly recommend this app to everyone who wants to learn words through the phonics method . It would be more than 5 star if developer could add an exam for each part without HINTS . so parents can really evaluate the learning process. ,

Powerful Intensive Phonics for Spelling

What We Liked:

I am a dedicated teacher of phonics as the primary method of instruction for both reading and spelling in our homeschool but I have had a hard time finding apps that do phonics well. Simplex Spelling Phonics 1 is certainly one of the best, most intensive spelling apps that I’ve found.

My daughter (8) loves that she can use this app independently to learn phonetic patterns of spelling that we haven’t yet covered together in our one-on-one learning times, but because it includes excellent direct instruction, this app can be used as a primary source of phonetic spelling instruction.

My favorite part of the app are the detailed explanations of phonetic concepts and rules, particularly the additional explanations that are available by clicking the white starburst in the phonics hints for each letter, and the arrow bars connecting silent e’s with the vowels they influence.

Most children learn well by recognizing patterns and the introduction of one phonics sound or pattern for each lesson helps children by grouping words together by sound and spelling pattern, making long-term retention more likely.

What We Didn’t Like:

I don’t think there is anything to really dislike here! My one caveat would be that the word lists span at least three grades, there isn’t a lot of depth given for any of the phonetic concepts, so if you have a kindergarten child, he’ll move through all the cvc offerings fairly quickly an the rest of the app will have to wait until grade one (unless your child is a precocious speller!) We are using it with my third-grader who isn’t a strong speller so that isn’t an issue for us, we’ve jumped in on phonograms she hasn’t used in her spelling yet because you can choose any of the 42 lists.

Parents might also want to note that there isn’t any direct teaching of syllabification/open syllables in this app, though many other phonics patterns are explicitly taught with the hints option.


Simplex Spelling Phonics 1 is one of the most powerful spelling apps for phonics I’ve ever used. The arrangement of 450 high frequency words according to phonetic sounds and principles, the self-correcting, direct-instruction, statistics, multiple users – it meets ALL of my criteria.

I received a promo code.
