The app will, Infosecurity notes, prove very useful for IT support staff in the field as it allows a wide variety of information and images to be shared in parallel with a standard voice call.
According to Thrutu, the company behind the smartphone software of the same name, the app has already been downloaded by more than 250,000 Android users in the four months it has been available.
Extending the app to the iOS platform says the firm, will significantly boost the software's popularity.
According to the company, Thrutu lets users instantly share all manner of interactive content and media during a phone conversation, including photos, location and contact information at the touch of a button.
To access Thrutu, iPhone users simply open the app and call any of their contacts - or Thrutu starts automatically when the phone receives an incoming call from a Thrutu user - enabling rich content sharing and interactions through a number of Thrutu buttons.
These buttons include live location sharing, the ability to take and share a photo, as well as contact information between the two devices, with the contact details appearing immediately in the other user's contact lists, even across the Android/iOS divide.
Other features include what the firm calls a playful `prod' using the handset's vibration facility. Other facilities are planned for the app says the company.
Liz Rice, Thrutu's vice president, said that Android users have responded very enthusiastically to Thrutu - and their number one request has been for an iOS version so they can use Thrutu with their iPhone-owning friends and family.
"This product release creates a whole new level of enriched communications between iPhone and Android that has not previously been possible", she said.
Alfredo Guilbert, vice president for West Coast & Asia at AlwaysOn, said that the extension of the app to the iOS platform is a positive move.
"This iPhone launch enables an even larger and more connected population to turn their ordinary phone calls into interactive and rich exchanges, and we think it will be hugely successful", he said.
Thrutu is available immediately in the App Store for iPhone 3GS and above and on the Android 2.1 platform or higher.
