Flash messaging, where Truecaller ‘calls’ a recipient’s phone to get a simple yes/no response through its app, is now on iOS. The feature can also be used as a distress signal, which is how it was originally conceived.

Flash messaging requires both the sender and receiver to have Truecaller, and to be connected to the Internet. With pre-written ‘smart answers’, users receiving a flash message can respond immediately to the message. The recipient’s phone rings at a very loud volume, which does not stop unless the user either presses the lock button or sends a response. The response is also delivered as a very loud ‘call’.

Of late, Truecaller has been moving to replace users’ phone app, rather than just acting as a layer over it which identifies incoming callers: this includes its custom dialer, its in-app messaging service (which Truecaller has tried to trick me into setting as default multiple times), and a call log.

Other Truecaller developments

This year, the company had tied up with Airtel for caller IDs, ICICI for UPI payments, and with Google for integrating the search giant’s Duo calling app. The arrangement with Google enables in-app Duo calls from Truecaller itself.

Previously, the company tied up with e-commerce firms like Snapdeal and Flipkart to whitelist incoming IVR or delivery agents’ calls. The company also allows its users to sign up on third party services using their login API, like BankBazaar and MobiKwik.
