Is their any competition or dependency between intercom and smartphone app based solutions like myGate ?

SHORT ANSWER:

Probably none to our judgement. The focus of each is different and complementary in the overall security and helper management function. Intercom is a tool that is targeted to do intra-facility voice-communications better than everything else out their in the market. It does not constraint the purpose for which the voice call is made in any way. Similarly myGate, AC and Adda gatekeeper are smartphone app or SaaS based solution to improve functional domains of apartment facility management like visitor management, attendance of helpers, etc. However we do not agree that myGate's solution  for voice communication based on cellular P2P calling is a drop-in replacement  or substitute for intercom for reasons mentioned above. At best myGate voice calling feature is only a cheaper replacement for proprietary Building intercom solution. 

DETAILED ANSWER:

Intercom is a pure communication tool with intelligence only for voice and video communication handling. myGate is a application specific tool with inbuilt Business intelligence for select applications like Visitor and Helper Management, which is outside the scope  of intercom service which is just a tool.  It still does not cater to hundreds of other use cases for intercom use in society as outlined in the initial part of this blog. We see it as a complimentary productivity enhancement service, not essential one. as an equal or more number of societies using 

1. ApartmentAdda Gatekeeper or ApnaComplex Gatekeeper along with intercom (See testimonials company websites)
2. Register and Intercom for small to medium societies
3. Manual Register and mobile, or just mobile-to-mobile P2P calling, if you find a way to maintain directory and keep it up-to date especially for smaller societies. 

and which are doing visitor management reliably for years on for improved security. But we observed that almost all big societies have an intercom in place.

One feature of myGate, which is a small bit of concern, is the ability of that application to use cellular calls *exclusively between resident and security (simplified by inbuilt directory) and the company's sales pitch that if myGate is used facility does not need to depend on intercom (which for a bigger society like us is a marketing hyperbole).  If you read our blog carefully, you will judge why we think this way based on scope and handicaps of cellular calling. We just hope owners and residents realise the implications of falling for such marketing hyperbole and arriving to the conclusion that they do not need to subscribe to the intercom service because society is also giving them myGate access. 

Also  at times smartphone apps are not easy or always friendly enough to be used by many senior citizens, kids, helpers, etc at home but they can easily use traditional phone due to prior experience and simplicity. They may just prefer traditional phone call (pick receiver-on-ring or dial-a-number to talk).
