Based on good research. Nice.

Description
The Bicycle Tire Pressure Calculator is used to compute the optimal air pressure for your bicycle tires. Tires pumped too hard bounce down the road like a basketball, wasting energy. Tires pumped not hard enough are sluggish and prone to pinch flats. Tires pumped just right are at the optimal intersection of responsiveness, shock absorption, and energy efficiency.Popular misconception is to pump a bikes tires to the highest number printed on the sidewall by the manufacturer. Instead, the optimal pressure is that which yields in a 15% sidewall drop. Sidewall drop is a non-linear function of the load on the tire and its width. It can be computed based on the weight of the bike, rider, bags, and gear. It is also different between front and back, depending on the frame geometry.With this App, you can instantly compute the optimal tire pressure from your phone or tablet wherever you may be: in your garage, on the road, at a friends house.Features:* Enter weights in either pounds or kilograms* Calculate pressures in either PSI or bar* Tire widths from 19 to 60 mm; diameters of 26", 650B, and 700C; 4 of the most typical frame geometries or user-defined measurements* Configure and save multiple bikes* Tap bike graphic to recalculate pressuresUpdated for more device compatibility.

Tire pressures are a tricky thing, but great things can happen when you get the perfect level of cush and speed. This app will help you get a good baseline or starting point to make fine adjustments from. There are going to be some things it can not model like variations in tire construction or accuracy of weight and loading, but it will get you in the ballpark for sure. After that, the fine tuning is done by trial and error. A good number of us have been riding our tires at too high a pressure for most of our lives, this app will help you find the path of comfort and speed.
Great App! 2 things I wish it had: The specific geometry listed for each bike type and a way to enter custom geometry. Other than that this is quite awesome!
Used this all the time on my droid3, fails to update on my droid DNA (HTC butterfly). Did have to tweak the weight distribution a bit for some touring bikes, but a noticeable difference in ride quality was seen.
Nice app. But the pressures of do seem to be run on the extremes. The rear pressure is huge on my road bike and the front almost running flat on my wife's mtb. I'm hoping for a few more common bike configurations in upcoming versions. I'm curious why there's a custom option but haven't found a way to configure it. (update) Can't upgrade to V1.3 as I get the -24 error mentioned by another. Looked at the potential fix and seemed too complicated and not well explained to bother with an upgrade. If you're an XDA developer, no big deal I guess.
I like this app. It makes a quick job of suggesting the correct tire pressure for your bicycle. Make your tires last longer and your bike ride nicer. Since most people run too much air in their tires, this should be on your phone.
It would be nice to see mountain bike geometries too.
