Very popular option for communication apps for iPhone and Android is an In-app purchase. Based on statistics from our mobile application development company customers, this features are mostly used in entertainment apps and communication apps, social media. This example is from a WebRTC chat app we built, demonstrating how time can be bought as an In-app purchase item.
Users can call each other inside this video broadcasting app for communication. While there are some free seconds, they are asked to purchase time to have more conversations. We used Stripe so that users can buy time credits with their credit cards. When time is purchased users can see their balance inside the WebRTC chat so that they can keep track of their expenses. And call is interrupted when user is out of credits.
As additional features to more complicated business instant messaging apps our mobile application development company suggests:
See purchase history
View current costs
Average time to develop business instant messaging app with In-app purchase option by a mobile application development company is3-4 MONTHS
You may also want to have a website for your business instant messaging app and in that case a mobile application development company may offer you to have a simple landing page for promotions. In that case a team will remain same. But if you want a website with a purchase option as well, you will need to add one more front-end developer to the team.
TWO FRONTEND DEVELOPERS
ONE BACKEND DEVELOPER
ONE UAT SPECIALIST
As a mobile application development company we have seen projects with many different budgets. How much mobile app costs does not depend on a complexity of a final product but it depends on a release stage. We usually use following stages: MVP, Beta Release, Launch.
