A lot of FLOSS developers work in their free time (unpaid). I can totally understand if Eternity hasn't had any activity within three months. Maybe they are busy or got bored of it. As long as it isn't abandoned (which i'd consider after 12+ months of inactivity) I am still very happy with it.
Absolutely fair! I had been using Eternity, and after a long period of no development began preferring other apps. Other apps have since caught up, and offer other features. Raccoon offers a good user experience, is open source, and I like the direction of development. I regularly have a few different apps on my phone at any given time, but this is one that stands out to me as a user.
