Does not support road tubeless

Does not support road tubeless

Not very flexible

The app uses very little input to determine right tire pressure. The tire range is limited and grouped together instead of individually being entered.

Nice but could be so good

I downloaded this app and liked the layout, problem is there is not enough tire widths included, would be great if this was added please

Limited and confusing

This might be a decent app, but out of the gate it has two glaring issues for me:

1. It only deals in weight by pounds (lb). I deal in kilos! There doesn’t seem to be any way to change your preference

2. More advanced calculations are available, but they’re a bit hidden away. You have to swipe left or right to page between them, which took me a while to discover

Pointless!

This app results are whacked out. Tells me 102 psi for 190 lb rider, and 195 psi for 210 lb rider and bike.
Stupid app!!!!

Meh. Useless.

Largest tire is 32, doesn't account for tubeless, tire TPI, road surface. Get an accurate gauge and a China marker, try different pressures, write them on the tire sidewall. Use the one you like best.

Inaccurate

Not useful. Gives pressure rec of 216 psi for rider and bike of 195 lbs.

Good only if you don't need it!

Only works for small people and skinny tires. If you are a bike racer, why bother? You already have a team mechanic to figure out your tire pressure!

Maybe I am missing something

Sample problem: plug in rider + bike weight = 205lb. Suggest 45/55 split between front and back, but results are 106.79 for both.

And, the pressures all seem a bit high, for example, when compared with Schwalbe's recommendations.

Need more choices.

The app is fairly neat. What it lacks is the ability to choose rim size and tire size. I ride plus and fat bikes. This app can't help me until the tire and rim selection is increased and/or made manual. It has the potential to be a cool tool.
