Lark vs WhatsApp: Which is best for you?

I like the calendar integration and collaboration in documents that make it easy to work with a team.

What I liked least are the security concerns which prevented me from putting this on my personal mobile device, and the cumbersome nature of file sharing where permissions issues slowed down the pace of work.

Whatsapp is best massage service app in world with free, best, simple interface with safety features like 2 step verification ,video call facility is good, there are no bugs and issues, customer service is good quick response etc.

Not too savage what I like least about whatsapp is the occasional group chat chaos too many people replying at once turns it into a noisy mess read receipts endless notifications and that 1 guy who spams voice notes you can't mute fast enough also the desktop version feels clunky compared to the phone app and there's no real way to organize or search old messages It's not a deal breaker but it can get overwhelming when things get busy.
