These days, with all the issues being raised on privacy with apps which are widely used (like WhatsApp), it may be worth looking at apps which are not so popular, but perform the same functions. Since such apps are not so widely used, they may not be a target for poachers. Rainbow is one such app.
It is a collaboration tool where you can chat, share files and use messaging for business and personal purposes. You can also instantly make audio or video calls and share your screen with just one click. In short, you lead your business with enterprise-grade control.
Besides, you don’t even have to share / disclose your telephone number to make calls.
It may be of great use in certain countries which ban WhatsApp calls!
An interesting alternative to WhatsApp – worth trying.
