Thank you so much for the referral!
Yes, we have successfully converted the Glide app into fully functional Android and iOS versions and published them on both the Google Play Store and Apple App Store.
We’ve already helped publish thousands of Glide-based apps to the app stores, and we’re excited to continue supporting creators like you in bringing their apps to a wider audience.
Please let us know if that sounds good to you, and we’ll be happy to move forward.
