Prodigy Math and Duolingo ABC teach different subjects to different ages, so this is not a straight fight. Prodigy is a free to play fantasy game for grades 1 to 8, where children answer adaptive math questions inside battles, quests, and pet adventures. Duolingo ABC is a free learn to read app for children ages 3 to 7, with short lessons on letters, phonics, sight words, and early reading, and no ads or in app purchases. If your child is learning to read, Duolingo ABC is the pick. If your child is in grade 1 or above and needs math practice, Prodigy is the pick. Many families use both, Duolingo ABC for the younger child learning letters, and Prodigy for the older child doing math.
What each one is
Prodigy Math is a role playing game. Children play as a wizard, explore a fantasy world, and answer math questions to win battles and earn pets and gear. The questions adapt to the child level and cover the full math curriculum, from counting and place value to fractions and algebra basics. A teacher or parent can set which topics appear, and the reports show which topics each child has mastered.
Duolingo ABC is a learn to read app from Duolingo. Children work through over 700 short lessons with the green owl, learning letter sounds, tracing letters, reading simple words, and building early reading skills through games and stories. It is completely free, with no ads, no subscriptions, and no in app purchases, and it is designed for the youngest learners, ages 3 to 7. For a comparison with another app aimed at young children, see Prodigy Math vs Khan Academy Kids.
Ages and who it suits
The ages barely overlap, which is the first thing to know. Duolingo ABC is for ages 3 to 7, and it is at its best for ages 3 to 6, when a child is meeting letters for the first time. Prodigy is for grades 1 to 8, about ages 6 to 14, and it is at its best from grade 1 upward, when a child is doing real math at school. A 4 year old belongs in Duolingo ABC, not Prodigy. A 9 year old belongs in Prodigy, not Duolingo ABC, because the reading lessons will be far too easy. The overlap is a 6 or 7 year old in grade 1 or 2, who may still be building reading skills and is also starting math, and that child can use both in the same week.
What they actually teach
Duolingo ABC teaches one thing: early reading. Letters, letter sounds, phonics, sight words, tracing, and simple stories. It does not teach math, and it does not try to. Prodigy teaches one thing: math. Counting, addition, subtraction, multiplication, fractions, and more, all the way through grade 8. It does not teach reading, although the questions are in English, so children do get reading practice while they play. Neither app replaces the other, because they cover different halves of the early school years. A child who needs reading help and a child who needs math help need two different tools, and these two are the free picks for each half.

Cost compared
| Feature | Prodigy Math | Duolingo ABC |
|---|---|---|
| Free version | Yes, full game is free to play | Yes, fully free, no ads |
| Paid version | Optional parent membership for game extras | None, no subscription exists |
| Who pays | Parents, only if they choose membership | Nobody, funded by the main Duolingo app |
| Subject | Math, grades 1 to 8 | Early reading, ages 3 to 7 |
| Ages | About 6 to 14 | About 3 to 7 |
| Device needed | Browser or app on most devices | Phone or tablet app |
| Teacher tools | Free teacher dashboard with math reports | None, it is a home app |
| Works offline | No, needs an internet connection | Yes, lessons work offline |
Both apps are free, which is rare. Duolingo ABC is free in the fullest sense: no ads, no premium tier, no in app purchases, and the whole app is open from day one. Prodigy is free to play, and the optional parent membership adds game extras, but it is not needed to practise math. A family pays nothing to use either one, so cost should not decide this comparison. Age and subject should.
In the classroom
Prodigy is built for the classroom. Teachers get a free dashboard, set assignments by math topic, and read reports that show which students have mastered which topics. Duolingo ABC is built for the home, not the classroom: there is no teacher dashboard, no assignments, and no class reports. A teacher who wants a reading app for the classroom would look elsewhere, but a teacher who wants math practice for grades 1 to 8 will find Prodigy ready to use. Parents, though, can use Duolingo ABC at home with no setup at all: hand the tablet to the child, and the app guides them through the lessons. The wider comparison with other math games is in Prodigy Math vs other math games.
At home
At home, use the app that matches the child age. A 4 year old gets Duolingo ABC for 10 to 15 minutes a day, learning letters and sounds through short games. A 7 year old in grade 2 gets Prodigy for math practice, and may still use Duolingo ABC if their reading needs work. A family with two children of different ages can run both apps on one tablet, and neither costs anything. Keep sessions short for the younger child, because early reading lessons work best in small daily doses, and let the older child play Prodigy for 15 to 30 minutes, with the teacher or parent checking the report at the end of the week.
Which one should you pick
Pick Duolingo ABC if your child is 3 to 7 and learning to read, especially if they are still on letters, sounds, and simple words. Pick Prodigy if your child is in grade 1 or above and needs math practice, especially if they avoid math work or need a lot of reps. Pick both if you have a young child learning to read and an older child doing math, or if one child aged 6 or 7 needs help with both reading and math. The two apps do not compete, they cover different subjects at different ages, and the right answer for most families is the one that matches the child in front of you.
Frequently asked questions
Is Duolingo ABC better than Prodigy?
For teaching a young child to read, yes. Duolingo ABC is made for ages 3 to 7 and teaches letters, phonics, and early reading. For math practice in grades 1 to 8, Prodigy is the better pick.
Can you use Prodigy and Duolingo ABC together?
Yes. They teach different subjects, so a family can use Duolingo ABC for reading and Prodigy for math, often for different children, or for one child aged 6 or 7 who needs both.
Is Duolingo ABC really free?
Yes. It is completely free, with no ads, no subscription, and no in app purchases. Duolingo funds it through its main language learning app.
What age is Duolingo ABC for?
Ages 3 to 7, and it is at its best for ages 3 to 6. A child older than 7 will find the lessons too easy, and should move on to reading real books.
Does Prodigy teach reading?
Not as a subject. The questions are in English, so children get reading practice while they play, but Prodigy teaches math. For reading, use a reading app like Duolingo ABC or a book library.
