The app measures lap times in 0.01-second increments with options for graph, table, or combined displays. Stored lap times can be output in CSV format and used as target times, which are drawn alongside measurement times on the graph.
The app converts an iOS device into a measurement and data storage tool when paired with a first-generation ULTRAPEN pocket tester. It offers wireless communication, an intuitive interface for measurements, and data export capabilities.
The app provides wireless remote measurement of voltage, current, resistance, and capacitance. Measured data transfers to iPhone via Bluetooth for visualization, storage, logging, and sharing.
Calculate altitude using GPS, ASTER, or barometer (iPhone 6 and later). Display average altitude from GPS and ASTER data. Show peaks, compass, and distance grid on an integrated map. Support Apple Watch. Choose unit of measurement.
Measure angles with precision up to 0.02°. Use surface and auto-select features for accurate readings. Convert angles between degrees, grade, and roof pitch. Includes a ruler for actual size measurements. No advertisements.
Digital measures ambient temperature using GPS and displays it in . Shows temperature in badge format with below-zero indicators. Includes to Celsius conversion calculator with formula.
Monitor atmospheric using the device's sensor. Display current location and air . Show weather conditions based on readings. Allow manual input for calibration. Track changes over time.
Measure ambient noise levels with an AI-powered noise meter that identifies noise types. Get accurate pressure readings and view audio waveforms. Sync data with the Health to track exposure and monitor hearing health.
Detects nearby objects by measuring magnetic field strength in microtesla. Displays real-time EMF levels. Alerts users when magnetic field increases, indicating presence. Shows comparison to natural EMF levels.
The app simulates a tool to measure levels on an iPhone or iPod Touch. It measures vertical, horizontal, and 45-degree angles with an optional sound warning for horizontal plane measurements under one degree.
