Give your kids everything they need to master hundreds of 4th grade spelling words all on their own. Spelling Ace combines simple, read-along lessons with smart spelling-bee-style adaptive practice questions to make learning 4th grade spelling skills faster and easier than ever before.

The app was design by an ex-Google product manager to enable his girlfriend's autistic son to achieve Common Core proficiency by himself, at his own pace. Lessons are as simple and effective as can be.


• 68 simple read-along lessons. Students can learn by themselves, often more quickly than from videos or lectures.
• Effective, adaptive practice. Each student sees a different set of questions that get harder over time. When they make mistakes, the questions change in real-time to maximize learning and minimize frustration, following the ‘spaced repetition’ learning theory.
• Text to speech. Tap on any word to have it read out loud.
• Auto-play. Sit back and enjoy the whole lesson read to you. Even kids with difficulties decoding text or paying attention can learn spelling skills on their own.
• Switch between up to 10 password-protected student profiles.
• Teacher View: Keep kids accountable for regular practice with minimal effort. Look at charts of useful metrics. See where students are struggling, and jump in to help.
• Gamification. Medals, progress bars, and uplifting interfaces motivate students to do their best.

Watch your child's grades improve with just a few minutes of regular practice.

Spelling Ace was developed by a team of veteran teachers, technologists, and student testers working over the last 2 years.

No parent wants to see their child fall behind. Yet over 50% of 4th graders weren't proficient in 4th grade common core standards in the US in 2017. Our own kids were struggling to keep up. We built Learn Spelling for them, and now they are excelling on their own. Your kids can too!

Great spelling tool for quarantine

I’m a mom and just had a blast doing a lesson with my son. He already learned a few words. The design is awesome. It’s super easy to use, and really focused on learning a lot quickly. The adaptive practice is really cool too. It helped my son really retain what he learned.

This is app is beautiful, simple, and very effective. It teaches spelling as well as vocabulary. My 4th grader has learned a lot already. I recommend it to any parent, tutor, or teacher.
