Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New in 1.2: • Home and Lock Screen widget: your recommended front and rear pressure, always at a glance (Pro). • Pressure check reminder: get a nudge weekly, every two weeks or monthly – with seasonal tips when it gets colder. • Rim inner width: wide rims make the tire wider – TireCalc now accounts for it. • Per-profile fine-tuning: adjust front and rear pressure by up to ±0.5 bar (±7 PSI). • The pinch-flat warning no longer shows up needlessly for road bikes. • Switching profiles now keeps the saved tire width.
