TideLock is an expanded (replacement) version of Regollith and the MoonLock applications also by Madvox. TideLock provides accurate ephemeris for the Sun, Moon and Planets as well as a number of additional useful resources such as orbital visualizations, timers, calculator, moon calendar, moon visibility, moon phase, rising and setting times, colongitude calculations, observational aids, etc.
TideLock has two purposes: On one hand, it is a useful tool for casual observers or the general public if you need to know what the current phase of the moon is or where the moon or planets are located. On the other hand, it is an observer aid if you are next to your telescope as it allows you to do the things mentioned above plus a number of other useful activities such as timing events, looking at proper time formats, display an HD map of the moon which can be zoomed into so that you can more easily locate features, etc.
TideLock v2.x is a redesign of the original program. There is a road-map for TideLock which includes upcoming features such as visualization of the moon in the horizon, star charts, timed events, asteroid tracking, imaging, and perhaps in time, Telescopic Interfaces.
