Hi Sameer! Hello English is definitely an awesome product which is tremendously engaging and has a niche of its own.
However, with Multibhashi we have a much more focused TG which comes from the bottom of the pyramid (think about the blue collar professional workforce who is probably beginning to acquire their first few English words).
With this kind of audience in mind, we have designed the product to be extremely mother tongue friendly which means all the new words, basic rules and day to day dialogues are introduced through an audio-visual explanation in their mother tongue (audios recorded by native speakers).
Besides this, we provide an active human support to our learners through one to one chat/call/video sessions once they complete certain milestones in the app. This, we think, is crucial for ensuring actual learning progress.
Multibhashi has been out for a little over 6 months and the response so far has been amazing (70k plus installs; 113% growth mom; 4.6 rating) and this proves that while there are many more sophisticated and feature-rich products out there in the market, a non-tech-savy beginner stage learner may be more delighted by a simple uncluttered goal based learning module which makes him/her feel at home. Sometimes, perhaps "less is more"
