SimAngle turns your phone into the two tools every sim racer needs when setting up a rig: a field-of-view calculator and a precision angle finder.

Stop guessing at your FOV and eyeballing your side monitors. Measure it, calculate it, set it once and forget it.

FOV CALCULATOR
• Single, triple and mixed screen setups
• Flat and curved screens (with curve radius)
• Works in centimetres or inches
• Common aspect ratios: 16:9, 21:9, 32:9 and more
• Returns horizontal and vertical FOV to enter in your game
• Tells you the ideal toe-in angle for your side screens
• Live top-down diagram of your eye point, screens and FOV cone
• Optional tape-measure guides so you know exactly where to put each screen
• Save the diagram to your photos or share it with friends and your league

ANGLE FINDER
• Uses your phone's gyroscope for precise angle readings, with an automatic compass fallback on devices without a gyro
• Works best on phones with a gyroscope – the app will inform you if it's running in reduced-accuracy mode
• Large, clear dial that is easy to read from your seat
• Zero the reading against your centre screen, then match the exact toe-in on each side screen
• Great for wheel decks, pedal plates, seat rails and monitor mounts
• Shows your calculated toe-in target from the FOV calculator right on the dial so you know when you've hit it

DIGITAL LEVEL
• Simple spirit level with a clear indicator when a surface is level
• Level your rig, stand and screens before you start measuring angles

WHY FOV MATTERS
A correct field of view gives you a true sense of speed, distance and car placement. Get it wrong and braking points, apexes and mirrors are all misleading. SimAngle uses the same maths as the well-known online calculators, but with a live diagram and an angle finder in the same app, so you can measure, calculate and adjust without leaving your rig.

WORKS WITH ANY SIM
The horizontal and vertical FOV values can be entered into any racing sim that lets you set FOV, including titles such as iRacing, Assetto Corsa, Assetto Corsa Competizione, rFactor 2, Automobilista 2, Le Mans Ultimate, F1, Gran Turismo style setups on PC and more. It is also handy for flight sims and anyone setting up a multi-monitor desk.

NOT JUST FOR SIM RACERS
The angle finder and level work on any surface, so SimAngle is also a useful pocket tool for DIY, woodworking, shelving, TV and monitor mounting.
