The app visualizes magnetism in three dimensions using the iPhone's magnetometer. It can be used to explore magnetic fields, detect metal, and estimate north-south position without GPS.
Calculate airflow displacement by inputting velocity or volume. Select duct type and dimensions with unit options. Instantly display results in preferred units including fl/min, m/s, and ft3/min.
Measure a car's engine power and torque with 2% accuracy using acceleration tests. Track 0–60 mph and 0–100 km/h times. Compare performance before and after tuning or upgrades. Export data for analysis.
Solve problems with a scientific calculator that handles standard and scientific notation with significant figure control. Calculate molar masses, convert between chemical names and formulas, and balance equations.
Logs 3-axis acceleration and rotational data, ground speed, altitude, distance, displacement, and course. Users can plot, replay, and analyze recorded data for experiments, sports, drones, vehicles, and security. Data is stored locally on the device.
