Hot Pressure

Hot Pressure is an offline-first track-day tire pressure sheet for club and amateur drivers who run one named session at a time. Open the app and you land on a fullscreen four-corner board: a top-down car footprint with large LF, RF, LR, and RR cards. Each corner shows cold PSI, hot PSI, computed gain (hot minus cold), and your target band—so you can read the whole set at a glance in the paddock. How a session works • Log cold pressures before you go out • Enter hot pressures when you return • Capture car, track, ambient temperature, session label, and best lap • The sheet auto-calculates per-corner gain, session average gain, and axle deltas (front vs rear, left vs right) Best-lap cold-start library Rank past sessions by best lap and instantly see which cold corner set produced those times. One tap recalls a proven baseline so you are not guessing from memory or a messy notebook. Built for real paddock use • Car garage profiles with tire size/compound notes, preferred cold baselines, and last-used hot targets • Track list with surface notes and typical ambient ranges • Filter history by car or track • Session timeline with incomplete-corner warnings before save • Compare mode: overlay two sessions’ corner gains on the same four-corner layout • Unit toggles for PSI/bar, °C/°F, and lap time Paddock seed pack included Sample cars (e.g. Spec Miata, GR86), tracks, and three demo sessions with realistic cold/hot sets so the board is useful on first open. Fully offline. Typed numeric entry only—no sensors, GPS, or network required. Data stays on your device with local persistence and simple unit/theme preferences. Know exactly which cold corner pressures delivered your best laps—and how much each tire gained—without spreadsheets in the paddock.
