The formula to calculate the monthly app revenue (AR) is:
\[ AR = \frac{D \times ARPU \times MAU}{1000} \]
Where:
Let's say the daily active users (DAU) is 1000, the average revenue per user (ARPU) is $0.50, and the monthly active users (MAU) is 30000. Using the formula:
\[ AR = \frac{1000 \times 0.50 \times 30000}{1000} \]
We get:
\[ AR = 15000 \, \text{USD} \]
So, the monthly app revenue is $15,000.
