UK and USA are the most expensive-one developer our cost $100-150, European developers calculate $40-80 per developer hour, Central Asia countries are the cheapest – $20-40 per hour. For our approximate estimation of how much does it cost to make an app like Viber.

Let’s assume that we would choose an average price of $50 per hour. At ThinkMobiles we have skilled app engineers for hire at $30 hourly rate.

iOS application Android application App for both platforms
