How would you estimate the number of potential customers for a new smartphone app in a specific city?

During my final year in college, I worked on a project to develop a mobile app aimed at improving student engagement on campus. To estimate the number of potential users, I first identified the total student population at the university, which was around 20,000. Then, I researched similar apps and found that about 30% of students typically download such apps. From there, I calculated that approximately 6,000 students could be potential users of our app. This experience taught me the importance of using available data and assumptions to make informed estimates.

While volunteering for a local non-profit, I helped develop an app to connect community members with local services. I started by identifying the population of the city, which was about 100,000. I estimated that around 15% of the population might be interested in using the app based on the demographics of people who typically engage with community services. This led me to estimate about 15,000 potential users. This experience highlighted the significance of understanding community needs and the demographics when estimating user bases.

In my first role as a marketing assistant, I was tasked with estimating potential users for a new fitness app launching in our city. I gathered data on the local population, which was around 500,000, and found that about 25% of people in urban areas are likely to use fitness apps. This led to an estimate of about 125,000 potential users. I also considered factors like age and tech-savviness, which refined my estimate further. This experience demonstrated how market analysis and user profiling are critical for successful product launches.
