Mayanet is a roster creation and gameplay aid tool for the iPad. It's got all units, stats, and point costs, and allows you to easily build lists for any army or sectorial. It also features weapons, skills, hacking programs, pheroware tactics, etc. It also contains an offline snapshot of the official Infinity wiki as a rules reference. When entering play mode for a roster, it allows you to record notes, either as freeform text or using specific settings for common skills such as camo, metachemistry, booty, etc. All of these notes are timestamped with the last time you changed them so that your opponent can easily see that you're not cheating. :-) As mentioned, this app is only available on the iPad. Unfortunately, I do not have the time or resources to attempt to port it to iPhone or Android. If you do have an iPad, though, you can get it for free on the App Store. I will post here as I update it, and always welcome suggestions and bug reports.
