Enjoy learning anytime anywhere.
Even when you are online and offline.
Single account. Sync everywhere.
​
You can use RainbowOne on iOS, Android, Windows, Mac, at school or at home. Login with the same account and continue reading where you left last time. All the answers in the e-book are synced across devices. E.g., your student haven't finish assignment at lesson, they can login at home and all the submitted data are there, no need to answer again.
Offline reading
​
Download the e-books beforehand and use it when internet connection is not available. All the answer data are stored in the device first. They will be synced to our cloud once the internet connection is back.
Same experience across devices
​
The user interface are the same across devices, therefore you don't have to learn again when using different platforms. RainbowOne runs on mobile phone too, but we recommend students to read at a larger screen.
