This project is aimed at finding mobile app profiles that are profitable for the App Store and Google Play markets. I'm working as a data analyst for a company that builds Android and iOS mobile apps.
My goal for this project is to analyse data from both stores to help my developers understand what kinds of free apps are likely to attract more users.

We have 7197 iOS apps in this data set, and the columns that seem interesting are: 'track_name', 'currency', 'price', 'rating_count_tot', 'rating_count_ver', and 'prime_genre'. Also, we have 10841 android apps in this data set and those that seem interesting are: 'App', 'Rating','Installs', 'Type', 'Price', 'Content Rating', 'Genres' Not all column names are self-explanatory in this case, but details about each column can be found in these data sets: documentation-ios and documentation-android.

Going through the Google Play data set long enough, we'll find that some apps have more than one entry. For example, the application Instagram has four entries:
for app in android:
name = app[0]
if name == 'Instagram':
print (app)

We need to remove the duplicate entries and keep only one entry per app since we don't want to count certain apps more than once when we analyze data.
We'll use the main difference which happens on the fourth position of each row, which corresponds to the number of reviews. The different numbers show that the data was collected at different times. We can use this to build a criterion for keeping rows. We won't remove rows randomly, but rather we'll keep the rows that have the highest number of reviews because the higher the number of reviews, the more reliable the ratings.
reviews_max = {}
for row in android:
name = row[0]
n_reviews = float(row[3])
if name in reviews_max and reviews_max[name] < n_reviews:
reviews_max[name] = n_reviews
elif name not in reviews_max:
reviews_max[name] = n_reviews
We need to confirm everything went as expected by printing the expected length which is 9,659 and the actual length in reviews_max.
print('Expected length:', len(android) - 1181)
print('Actual length:', len(reviews_max))
Expected length: 9659 Actual length: 9659

already_added = []
for app in android:
name = app[0]
n_reviews = float(app[3])
if (reviews_max[name] == n_reviews) and (name not in already_added):
android_clean.append(app)
already_added.append(name)
After using the reviews_max dictionary to remove the duplicates in the cell above by using keeping entries with the highest number of reviews, in the code cell below we will explore the android_clean set to ensure everything went as expected.
explore_data(android_clean, 0, 3, True)

All these characters that are specific to English texts are encoded using the ASCII standard. Each ASCII character has a corresponding number between 0 and 127 associated with it, and we can take advantage of that to build a function that checks an app name and tells us whether it contains non-ASCII characters.
Some English app names use emojis or other symbols (™, — (em dash), – (en dash), etc.) that fall outside of the ASCII range. Because of this, we'll remove useful apps if we use the function in its current form. To minimize the impact of data loss, we'll only remove an app if its name has more than three characters with corresponding numbers falling outside the ASCII range. This means all English apps with up to three emoji or other special characters will still be labeled as English. Our filter function is still not perfect, but it should be fairly effective.

As we mentioned in the introduction, our aim is to determine the kinds of apps that are likely to attract more users because our revenue is highly influenced by the number of people using our apps.
To minimize risks and overhead, our validation strategy for an app idea is comprised of three steps:
Because our end goal is to add the app on both the App Store and Google Play, we need to find app profiles that are successful on both markets. For instance, a profile that might work well for both markets might be a productivity app that makes use of gamification.
Let's begin the analysis by getting a sense of the most common genres for each market. For this, we'll build a frequency table for the prime_genre column of the App Store data set, and the Genres and Category columns of the Google Play data set.
def freq_table(dataset, index):
dictionary = {}
total = 0
for row in dataset:
total += 1
genre = row[index]
if genre in dictionary:
dictionary[genre] += 1
else:
dictionary[genre] = 1
dictionary_percentages = {}
for key in dictionary:
percentage = (dictionary[key] / total) * 100
dictionary_percentages[key] = percentage
return dictionary_percentages
def display_table(dataset, index):
table = freq_table(dataset, index)
table_display = []
for key in table:
key_val_as_tuple = (table[key], key)
table_display.append(key_val_as_tuple)
table_sorted = sorted(table_display, reverse = True)
for entry in table_sorted:
print(entry[1], ':', entry[0])
display_table(ios_final, 11)
print ('\n')
display_table(android_final, 9)
print('\n')
display_table(android_final, 1)

We can see that among the free English apps, more than a half (58.16%) are games. Entertainment apps are close to 8%, followed by photo and video apps, which are close to 5%. Only 3.66% of the apps are designed for education, followed by social networking apps which amount for 3.29% of the apps in our data set.
The general impression is that App Store (at least the part containing free English apps) is dominated by apps that are designed for fun (games, entertainment, photo and video, social networking, sports, music, etc.), while apps with practical purposes (education, shopping, utilities, productivity, lifestyle, etc.) are more rare. However, the fact that fun apps are the most numerous doesn't also imply that they also have the greatest number of users — the demand might not be the same as the offer.
The landscape seems significantly different on Google Play: there are not that many apps designed for fun, and it seems that a good number of apps are designed for practical purposes (family, tools, business, lifestyle, productivity, etc.). However, if we investigate this further, we can see that the family category (which accounts for almost 19% of the apps) means mostly games for kids. Up to this point, we found that the App Store is dominated by apps designed for fun, while Google Play shows a more balanced landscape of both practical and for-fun apps. Now we'd like to get an idea about the kind of apps that have most users. The difference between the Genres and the Category columns is not crystal clear, but one thing we can notice is that the Genres column is much more granular (it has more categories). We're only looking for the bigger picture at the moment, so we'll only work with the Category column moving forward.
genres_ios = freq_table(ios_final, -5)
for genre in genres_ios:
total = 0
len_genre = 0
for app in ios_final:
genre_app = app[-5]
if genre_app == genre:
n_ratings = float(app[5])
total += n_ratings
len_genre += 1
avg_n_ratings = total / len_genre
print(genre, ':', avg_n_ratings)

This idea seems to fit well with the fact that the App Store is dominated by for-fun apps. This suggests the market might be a bit saturated with for-fun apps, which means a practical app might have more of a chance to stand out among the huge number of apps on the App Store.
Other genres that seem popular include weather, book, food and drink, or finance. The book genre seem to overlap a bit with the app idea we described above, but the other genres don't seem too interesting to us:
Weather apps — people generally don't spend too much time in-app, and the chances of making profit from in-app adds are low. Also, getting reliable live weather data may require us to connect our apps to non-free APIs.
Food and drink — examples here include Starbucks, Dunkin' Donuts, McDonald's, etc. So making a popular food and drink app requires actual cooking and a delivery service, which is outside the scope of our company.
Finance apps — these apps involve banking, paying bills, money transfer, etc. Building a finance app requires domain knowledge, and we don't want to hire a finance expert just to build an app.

In this project, we analyzed data about the App Store and Google Play mobile apps with the goal of recommending an app profile that can be profitable for both markets.
We concluded that taking a popular book (perhaps a more recent book) and turning it into an app could be profitable for both the Google Play and the App Store markets. The markets are already full of libraries, so we need to add some special features besides the raw version of the book. This might include daily quotes from the book, an audio version of the book, quizzes on the book, a forum where people can discuss the book, etc.
