Hi, yes Adalo supports multiple languages, including Arabic. However it requires some custom adjustments. I can help you set it up so your app displays perfectly in Arabic with proper alignment and design flow. You can reach me at fadekunle055@gmail.com I’ll be glad to assist you.
If you could share the details of custom adjustments which are required specifically for Arabic, I believe that would be quite useful for other app Makers.
Otherwise, please keep in mind that “Get Help” forum section is dedicated for asking for help and helping others, not for advertising one’s services.
