It's interesting to see how your app's installation numbers didn't quite match the market share distribution between iOS and Android. It seems that despite iOS having a smaller market share, you had a higher percentage of installations on iOS. And it's not surprising that iOS users are more likely to spend money on apps.
Choosing the right platform for your app can be a challenging decision, especially considering factors like user base and potential revenue. While your experience may not be representative of every case, it does highlight the unique dynamics at play in different app ecosystems.
The article you shared provides an insightful summary of your decision to move away from centralized stores. Exploring alternative distribution channels like F-Droid/Obtainium/Aurora could potentially reach different audiences, although it might come with its own set of considerations.
Regardless, we wish you all the best in any future endeavors and hope that new opportunities arise for further development or ventures!
