I had the chance to test both of these out. I thought you guys should know before you buy....This is just my opinion....I have been using both of the apps for a week now. UF has a lot more options to configure which is great. The app is tailored around the user. Litchi is more basic. Ken, the maker of UF, is very helpful if you have a problem and if you joined the Google group, he responds right away. One thing I don't like is that once you buy Litchi, you have to pay AGAIN to use the Orbit feature. I was really turned off about that. Its not the $3.50, its the principle. You pay for an app and then they want more money. UF is pay in one shot and that's it. And if you want a feature implemented into the UF app, Ken would be more than content with coding it, as long there is a consensus and as long as its not a stupid request. Try out UF and you wont be disappointed.
