CanDash

CanDash turns your iPhone into the dashboard your car deserves. Seven handcrafted gauge clusters — from analogue 1950s elegance to modern race-day digital — display live data from your car's OBD-II port. Choose your style. Customise every gauge. Build the dash you've always wanted. Then take a peek under the bonnet. CanDash reads fault codes, monitors your check engine light, tracks performance, and helps you understand what your car is telling you. All offline. All private. — GAUGE CLUSTERS — • Street — clean modern enthusiast dials • Race — brushed metal and red glow, supercar-inspired • Mille Miglia — warm copper and chrome, vintage road-racing • Stuttgart — German sports car heritage • Swiss — haute-horlogerie precision with gold needles • 90s Retro — amber-on-black retro aesthetic • Digital — modern race-digital display • Plus a fully customisable Dashboard — DIAGNOSTICS — CanDash reads fault codes from your vehicle's engine and transmission ECUs.
