## Most critical reviews (10 lowest-rated)

### 1/5 — Does not support road tubeless

*2021-08-11*

Does not support road tubeless

### 1/5 — Not very flexible

*2020-06-13*

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

### 1/5 — Pointless!

*2017-04-25*

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!!!!

### 1/5 — Meh. Useless.

*2016-09-27*

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.

### 1/5 — Inaccurate

*2016-09-27*

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

### 1/5 — Good only if you don't need it!

*2016-09-24*

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!

### 2/5 — Limited and confusing

*2018-12-11, version 1.1*

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

### 3/5 — Same as rug boy

*2025-05-15*

Only good for road bikes, not mountain or hybrid commuters

### 3/5 — Nice but could be so good

*2020-06-12, version 1.1*

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

### 3/5 — Maybe I am missing something

*2016-09-22*

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.

## Most praised reviews (1 highest-rated)

### 3/5 — Need more choices.

*2016-09-21*

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.
