Got this app by redeeming a voucher so at least it didn't cost me anything. just as well as it doesn't really seem to work. The results obtained are wildly different to those obtained by using the Excel spreadsheet this app is supposedly based upon. Even when entering actual wheel loadings taken from static load readings using a scales the results are bizarre. Rear wheel results are hugely high and front wheel results very low. Using the 60/40 rear/front weight differential pre-sets the results just don't add up either, as the examples shown above demonstrate! Back to using common sense then! As a postscript to this review I'd like to say that I contacted the publisher about it's shortcomings and received an answer that suggested a degree of in-built inaccuracy was acceptable to them as it only affected results at the outer edges, so-to-speak, of the results 'envelope'. I'm a 145lb rider on an endurance-type road bike with medium-width tyres so should hardly be at any extremes as far as tables or calculations are concerned! In the hope that future updates and de-bugs of this app may actually make this app useful I'll hang on to it. Watch this space.
Glad I paid the couple of bucks No bike in my household fits any of the generic categories, so I am very happy to be able to work with the "custom." I LOVE not overinflating my tires, and having a far better chance of staying upright on rain-slick roads. I'm grateful for far less rattling of teeth. Everyone I've tried to market this to is an iPhone user, so I hope you write a version for them, too.
Seems like a great app. Minus one star since the Android Menu isn't working (at least not on my OnePlus Two) and so I cannot switch to metric units.
Have to use Custom to get pressure right by using custom the calcs run within one psi f/r of Heine or the Bike Tinker spreadsheet.
Looking for Hybrid and MTB Would be nice. For now I'm trying to figure out which of the existing ones are close enough that I could use them instead. They based on the front to rear weight ratio by any chance?
Berto pressure calc Excellent, good range and serves me well. A couple more profiles I.e. hybrid, etc would be helpful but overall very nice.
* Updated with more recent android libraries for device compatibility.
* Minor UI updates/fixes.
