This app has really helped my daughter love reading and build her confidence as a new reader. She literally asks if she can read with Ello instead of watching cartoons!

This app is fantastic!!!! It makes reading so fun, my special needs 8 yr old has read 20 books in 3 days and already improved so much in such a short time!!! My 6 year old is now reading ahead for his age also, they love it and I love the daily updated progress reports! With 5 kids we have tried so many reading programs and apps but Ello is sooooo much better and an amazing value for what you get!

Maaaaaaaaaan, I'm a mom of four and pregnant with my last baby. My husband and I were struggling so hard with helping all the kids on their different grade levels of reading. Ages 5, 6, 8, & 10. Look this app got EVERYONE on track in only a few months. Scores on reading test came back yesterday and I started crying. I prayed for help, tried hooked on phonics, waste of money. Tried abc mouse, waste of money, but ELLO! Yeah Ello did its big one. It's affordable like cheap as it gets & still better than all the rest. Try it.

My struggling students started using this app and I saw improvement DAY ONE. So grateful for the program — the students love it; it boosts their confidence and increases skill level in more subjects than just reading. I don't know what I would have done without Ello.

My 8yo is very behind on reading. We downloaded today and I promise within 10 minutes she's was reading more confidently and chose on her own to keep going (she's always hated practicing reading). I asked if she likes it, she said "YEAH! It's way better than what y'all have me do." 🤣

I don't usually leave reviews, but this app changed our lives! My first grader was really struggling with reading and writing. She would get frustrated often and break down, leading to tantrums. Ello really broke it down and made things easier for her to understand with the guided reading. She loved reading now and upped a reading level in one session!

My daughter has tried tons of apps, pointless subscriptions she would only try out for a day and not get any interest or that much interaction with. This is hands down the first app she loved. I was surprised with how much interaction there was with her and how carefully it actually listens to the correct letter sound to move forward. Also the help if she needs it. Her goal was only 10 minutes today and she herself stayed on for 45 minutes. Couldn't be happier.

In just 4 months my child has gone from not reading at all to reading full sentences with ease. Ello has been a game changer.

Love love love!!! My kids are so into Ello, they actually are fighting over who uses my phone first to read when they got home from school. Never thought I'd find a program my older son likes to read with!
