TPE is a universal app with optimized user interfaces for both iPad and iPhone/iPod Touch devices.

TPE's map-based approach means you aren't limited to a predefined list of locations, which often miss the places many photographers go. Instead, search for any place name on the planet or position the map pin exactly where you want it.

Advanced features including visual sun and moon search, automatic time zone and elevation detection, correction for atmospheric refraction and height above the horizon, ensuring that you have the best possible information for planning your shoot.

You can even determine when the sun or moon will be visible behind nearby hills and mountains.

Customer Reviews

Great tool

I'm doing architectural photos and this app is great at showing the position/ angle of the sun at a particular time, and date. It even gives you estimate of shadow size.
I had a little trouble understanding the interface, but there's plenty of help online. It saves so much time! You don't go to a site at the wrong time. We'll worth the cost.

Useful photography tool

There are many cool features in this app to help photographers know exactly where the sun and moon will be at all times. The only thing that keeps this from being a 5 star review is that the program crashes on the iPad if I zoom in too far. It happens 100% of the time. Works like a charm on the iPhone though. Worth a purchase. Please developers, fix the iPad freeze when zooming.

Great program

Very useful program. Desktop version much eaiser to use but having it in the field is a big plus. I use it for so many different things, not just for photography. New features keep getting added and the application just keeps getting better!
