Hours for Android allows you to calculate planetary hours for virtually any date and any location on the Earth using super-precise Swiss Ephemeris. It doesn't need an internet connection as it is completely self-sufficient. If you don't remember the symbol of a planet, just tap on the corresponding row and you will see both the name of the planet and some keywords for it.
