About this app

Correct tire pressure means safety, better fuel economy and tires that last longer. The problem: nobody remembers the number while standing at the air pump.

Tire PSI solves it with one photo. Photograph the sticker on the driver door jamb and the AI reads the numbers the manufacturer set for your exact car: front and rear, and when the sticker lists full load and the spare, those too.

What you get
• Photograph the sticker, the numbers are read automatically
• Switch between psi, bar and kPa with one tap
• My cars: every car you scanned stays on your phone, even offline
• Sticker proof: a crop of your photo is kept next to the number so you can see where it came from
• No sticker? Pick your model from a list built from other drivers' scans, and if your model is not there yet, get an estimate clearly marked as one
• "Tires are hot" switch: just been driving? The app adds the usual correction
• A monthly reminder to check pressure, off by default
• 12 languages, pick yours inside the app

No account, no sign-up, no personal data collected. Photos are never stored on the server. Free, with one small banner.

Important: the numbers are read from the sticker in your car or from other drivers' scans; in some cases they are an AI estimate and are labelled as such. The sticker in your car and the owner's manual are the authoritative numbers. Measure when the tires are cold.
Photograph the sticker on your door and get the pressure your car's maker set.
