Blend.Life in 2021 is a RELAUNCH/2.0 VERSION of an initial solution launched back in 2013 - 2016 as a mobile consumer productivity app. So I'm going to summarize the history from 2013-2015
The MVP was built in under 3 months using a fairly minimal version of the feature set envisioned. It contained a few basic pages of Events, Tasks, and Birthdays. This MVP was for Windows Phone ( when it still existed ). I was the only developer but had 1 person doing some testing.
I got this into both the Windows Phone Store in 3 months tops, and in Google Play ( Android ) about 9 months after. This gave me an easy introduction to mobile development and understanding the consumer mindset. I soon ported it over to Android, launched it in google play in early 2014 I believe.
It was easy to get users fairly soon on Windows Phone as there weren't that many apps to begin with. On Android it was more difficult as the Android market was flooded with apps and very specialized apps ( e.g. 1 app for a specific purpose ). Not an combined one.
Over the next year, I kept iterating and improving the apps for both Windows and Android, including combination of Calendar Events, Tasks, Bills, Countdowns to important days and also improvements to Weather. The user base started growing for both.
The iteration and improvements on Windows Phone resulted in believe over several thousands of users, earning almost $1-2K a month or so. The Android base was starting to grow slowly and Then in July we got featured on some news sites for Android and that resulted in a spike of users/installs, and some steady active members.
