How can I share my kodular application with few others for testing in their own mobil devises?
Is there any free service like google playstore?
I have shared using WhatsApp, but lately it is showing error even when they try to install it from download folder.
Both aia or apk can be uploaded to your Google Drive. If you have a Gmail account, then you have a Google Drive storage space. After uploading it, get the link and give it to your users.
Just make sure they allowed installations from unknown sources in their devices:
