In the MX Player application, a new feature was introduced where, during music playback, the player switches to a new theme. The goal was to move away from the old, simple interface to a more user-friendly environment.

However, what actually happens is that once you enter this new environment, the entire application changes—not just the appearance. For example, the way you access files and how they are categorized is also altered.

Let’s say a song is playing—you can no longer figure out how to return to the folder where the song was originally played from. Also, the categorization of music by folders is completely different, and in most cases, you can’t find the song you’re looking for.

In this case, it would have been better if only the music playback interface had changed, while the file directory environment remained the same. Alternatively, the app could have asked for user confirmation before applying such changes, so users wouldn’t get confused when trying to play their music.

Most users organize their music files manually, so the file access section should have retained the previous design—or the changes could have been rolled out gradually over several updates, allowing users time to adjust.

🔷 Model 1 Report: Revenue Analysis of Café Bazaar Based on Developers and App Income

1. Introduction and Objective

Café Bazaar, as the largest Android app marketplace in Iran, earns its revenue primarily through a share of app sales, in-app purchases, and advertisements.
In this model, an attempt has been made to estimate Café Bazaar’s annual revenue using base data such as the number of active developers, the average monthly income of each revenue-generating app, and market growth rate.
The purpose of this analysis is to better understand the market potential and Café Bazaar’s revenue growth trends in the coming years, so that product managers can make proper financial and strategic planning.

2. Initial Assumptions and Input Data

3. Calculation Process

3.1. Calculating Next Year’s Number of Active Developers

Assuming an 18% annual growth:

N1=30,000×(1+0.18)=35,400 developersN_1 = 30,000 \times (1 + 0.18) = 35,400 \text{ developers}N1​=30,000×(1+0.18)=35,400 developers

This represents the estimated number of active developers for the next year who can produce revenue-generating apps.

3.2. Calculating Average Monthly Revenue per App with Inflation

R1=40,000,000×(1+0.5)=60,000,000 tomansR_1 = 40,000,000 \times (1 + 0.5) = 60,000,000 \text{ tomans}R1​=40,000,000×(1+0.5)=60,000,000 tomans

3.3. Calculating the Number of Revenue-Generating Apps Next Year

$$\text{Revenue-Generating Apps}=7,200\times (1+0.18)=8,496\text{ apps}$$

3.4. Calculating Total Annual Revenue of All Apps

$$\text{Total Revenue}=8,496\times 60,000,000\times 12=6,117,120,000,000\text{ tomans}$$

3.5. Calculating Café Bazaar’s Share from Developer Revenue

Café Bazaar usually deducts a percentage of developer revenue as commission:

$$\text{Bazaar’s Share}=6,117,120,000,000\times 0.15=917,568,000,000\text{ tomans}$$

3.6. Calculating Café Bazaar’s Advertising Revenue

It is assumed that 20% of Bazaar’s total income comes from ads:

$$\text{Ad Revenue}=917,568,000,000\times 0.20=183,513,600,000\text{ tomans}$$

3.7. Calculating Total Annual Revenue of Café Bazaar

$$\text{Total Revenue}=917,568,000,000+183,513,600,000=1,101,081,600,000\text{ tomans}$$

4. Final Result and Analysis

Based on the above assumptions, it is expected that Café Bazaar will earn close to 1.1 trillion tomans in the coming year. This figure includes direct revenue from app sales and in-app purchases, as well as advertising income.

This model shows that growth in the number of developers and significant inflation in the market can lead to substantial revenue growth. However, for more accurate forecasting, other factors such as market competition, policy changes, and user behavior shifts should also be considered.

🔷 Model 2 Report: Revenue Analysis of Café Bazaar Based on Transaction Volume and Paying Users

1. Introduction and Objective

This model focuses on Café Bazaar’s income through the number of financial transactions (e.g., app purchases, in-app payments, etc.) and the average income from each transaction. The goal is to forecast annual revenue considering inflation, transaction growth, and growth in paying users.

2. Initial Assumptions and Input Data

3. Calculation Process

3.1. Calculating the Number of Transactions Next Year

T1=46,000,000×(1+0.18)=54,280,000 transactionsT_1 = 46,000,000 \times (1 + 0.18) = 54,280,000 \text{ transactions}T1​=46,000,000×(1+0.18)=54,280,000 transactions

3.2. Calculating Average Revenue per Transaction with Inflation

R1=43,000×(1+0.5)=64,500 tomansR_1 = 43,000 \times (1 + 0.5) = 64,500 \text{ tomans}R1​=43,000×(1+0.5)=64,500 tomans

3.3. Calculating Total Transaction Revenue for Next Year

$$\text{Total Revenue}=54,280,000\times 64,500=3,501,060,000,000\text{ tomans}$$

3.4. Calculating Café Bazaar’s Share of Transaction Revenue

$$\text{Bazaar’s Share}=3,501,060,000,000\times 0.15=525,159,000,000\text{ tomans}$$

3.5. Calculating Advertising Revenue of Café Bazaar

$$\text{Ad Revenue}=525,159,000,000\times 0.20=105,031,800,000\text{ tomans}$$

3.6. Calculating Total Annual Revenue of Café Bazaar

$$\text{Total Revenue}=525,159,000,000+105,031,800,000=630,190,800,000\text{ tomans}$$

4. Final Result and Analysis

According to this model, Café Bazaar is projected to earn around 630 billion tomans in the next year from the sum of transaction revenue and advertising revenue.

This model is based on transaction volume and paying user behavior, reflecting the financial dynamics and transaction activity in the market.

🔷 Overall Summary

• Model 1 focuses more on the number of developers and the average income per app, and it estimates revenue around 1.1 trillion tomans.

• Model 2 is based on transaction volume and income per transaction, estimating revenue around 630 billion tomans.

The difference between the two estimates arises from different assumptions and perspectives toward the market.
Combining and comparing these two models can provide a more realistic picture of Café Bazaar’s revenue outlook.
