This can easily become a top quizzing contender if it continues to improve. Here's what we like a lot:
✅ Sufficiently intuitive UI and runs smoothly
✅ Decent amount of templates for a headstart
✅ Screen advance on click
✅ Very good customization tools
✅ Wide library of fonts, stickers, content/media/interaction elements, iframe, calendar etc
✅ Ability to autosend email on completion
✅ Decent amount of native connections including Google Sheets
✅ Story scheduling
✅ Cname and multi-workspaces
✅ Lead capture friendly
✅ Very good analytics which can be drilled down to 'user'

The list is probably longer, but we're still exploring. Keep up the great work. We tried putting in meta deta, but it didn't show up in Whatsapp. It would also be nice to have an option for the background wallpaper to be transparent or have a transparent/dark overlay (not completely block out the back). Also, not sure if the ability to take pics/video and make stories on the go is available but that would be neat. Also, we thought it would be neat to incorporate probably some kind of 'teleprompter' functionality here (borrowing from BigVu) since it's a decent feature for content creation on phones. Or probably, your goal is to leave editing on the desktop to create powerful stories for viewing on the phone. Either way, in it's present state it's a decent content creation kit. Give it a try..
