Very useful, well designed, and unintrusive bit of general geological reference. Thank you much, Sir.

good startSimple geo time scale; glad to see this app and want to encourage its continued development. Data and info appear good/accurate. Personally I hate the color scheme; some are difficult or impossible to read (such as white text on yellow bg next to Neogene). Placement of the "evolution" icon on the main screen is confusing; makes it look like apes were present in the Proterozoic. Top row needs labels (i.e., Eon, Era, Period, Epoch). Would like a direct "info" button for each Era/Period/etc.

Color needs to be better. Hard to read outside with white text. Should consider black text.

Some key features neededThe columns aren't labelled epoch, era etc. You also can't see the whole time scale in one scrollable view.
