LanxCalc
Blind Phalanx Calculator for Ogame
LanxCalc is a relatively simple program that can assist you in calculating return times of fleets you see on sensor phalanx scans.
It can calculate definite return times from attack and transport missions as well as return time intervals in case of a recalled deploy.
It is compatible with OGame v7, so it has new ships included and class bonuses are taken into consideration.
