We have been receiving a lot of queries about a version of MetrO for Android in the last few months and it may be time we elaborate on the "under evaluation" status that appears on our website.
First, don't worry, not only have we heard your (loud) message but I have been using an Android phone (for about one year) and I strongly believe in its future: we will port MetrO to the Google platform!
Unfortunately, there is only the two of us (with daytime jobs) to maintain our existing versions of the program AND to keep our city data up to date. The latter takes me more than 3/4 of my free time, since there are so few people helping us with the task, and what would be the use of the program with obsolete information?
As some of you may know, our iPhone version is far from beeing complete and I struggle to find some time to bring it to the same level as our other versions. As a direct consequence, I have tried to focus as much as possible on the iPhone first and keep Android for a later time.
Given the rising success of Android phones in the market and the demand you generate, I will try to adjust my focus in the near future: I expect to deliver a new iPhone version soon (now under testing) and I will begin working on Android right after that, maybe before the end of the month, if everything goes fine.
But, please, don't get too excited, there is a lot to do before you see MetrO on the Android Market and it may take a few months, even for a "raw" version!
I think that's all we can tell on the subject today, now please stop sending us mails about it (you may comment here instead).
And help us updating our city data so we have more time for the development!
Update (July 31st, 2011): a preview version is now available. See details here.
