TechKnow With Tantra: Rainbow

These days, with issues 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. ‘Rainbow’ 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. 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.
