I made it to learn Android development. It took me total of 5 days: 2 days to learn basic android stuff then next two days to develop this app and on last day creating dev account and publishing on Android store.
After publishing I forgot the password of signing key I used, so I never updated this app except for a description change. Initially there was almost no revenue but it increased over the time as the download count increased. After two year(of publishing), it is giving me around $70/per month through ads (admob).
