It does not work. ### 1/5 — Newest update doesn’t work *2021-08-31* This app worked just fine and my daughter used it for school last year, this year when we went to use it again it required an update. As soon as I updated it the app stopped working. It flashes white and crashes. **Developer response:** Thank you for sharing this feedback. We identified a workaround for you to try out: please delete the Amplify Boost app. Then download it again from the App Store. ### 1/5 — QR code doesn’t work *2021-06-15* Trying to test for students in my class. It will not scan their QR code. **Developer response:** Thanks for sharing this feedback with us. Please reach out to Amplify's Support team for help with troubleshooting. They can be reached at 1-800-823-1969. ### 1/5 — Can’t Use *2020-08-17* My son’s teacher suggested this app and my little dude was so excited to use the same app as his teacher. When you open the app they ask for login info or QR code but there is nowhere to set up an account. I cannot understand what the developers were thinking... **Developer response:** Teachers generate credentials because this app is tied to a program your child's school purchased. If you would like your child's teacher to give you a QR code, they can follow the instructions here: https://burstbase.net/dibels-8/intervention-faqs/using-mclass-interventions-new-practice-app/#GettingStarted If you would like a username and password, your child's teacher can watch this video to learn how to generate them: https://www.youtube.com/watch?v=Acrl0bp5sTY&feature=youtu.be ### 1/5 — Username error annoying! *2018-12-02* This app keeps asking for a username and password when one was not established during the install. It only gives an error message and no redirect to resetting the password. My child is highly disappointed. **Developer response:** Teachers generate credentials because this app is tied to a program your child's school purchased.

Please fix! **Developer response:** Very sorry for this! If you're still not able to log in, can you contact the Burst Support team at edsupport@amplify.com or (800) 823-1969 Option 5? We'll get this sorted for you as soon as possible. ### 1/5 — BOOST *2017-10-04* This app is not working with ios11. It keeps kicking you off. **Developer response:** Thank you so much for letting us know - we adjusted Boost to work on devices with iOS 11 a few days after hearing from you. We've also updated our process, so we can fix iOS bugs ahead of Apple's releases. ### 2/5 — Worked Great Until Newest Update *2021-03-05* My students used the app daily until the newest update. Now it opens, flashes white, and closes out. I hope they fix it soon. **Developer response:** Thanks for reaching out to us. Here's a way to resolve this issue: please delete the app from your device, then download it again from the App Store. ### 2/5 — QR Code Error *2020-02-06* The QR code log ins do not work, it shows an error message. However the username and password log ins do work, but the QR code would save more time. ### 5/5 — I want IOS 26 support *2025-09-17* I want IOS 26 Support ## Most praised reviews (1 highest-rated) ### 5/5 — Boost *2022-03-10* Our students LOVE these games. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
