Toolhub

Field diagnostics in your pocket. Live magnetic-field readings, MagLink signal detection, and data logging for directional-drilling crews.

ToolHub puts a suite of MWD field instruments in your pocket. Using your iPhone's built-in magnetometer, it detects MagLink signals, measures magnetic-field strength in real time, and logs raw sensor data — no extra hardware to carry to the rig.

Built by Erdos-Miller for directional-drilling and MWD crews who need quick, reliable field checks at the wellsite.

TOOLS

• MagLink Detector: Watch for MagLink sync pulses in real time. A live timeline shows detections over the last 60 seconds, with a running sync count, target rate in Hz, and a timestamped log of recent syncs — so you can confirm signal at a glance.

• MagField: Read magnetic-field strength live, straight from your device. On-screen readout plus audio feedback tells you instantly when the field is clear or saturated, with orientation guidance to help you take a clean measurement. The screen stays awake while you work.

• Magnetometer Logger: Capture raw three-axis magnetometer data with a configurable sampling rate, live readings in microtesla (µT), and performance stats. Review and share your logs when you're done.

WHY TOOLHUB

• No extra gear — your phone is the instrument • Real-time readings designed for the field, not the office • Clear visual and audio feedback you can use with gloves on • Fast, focused tools that do one job well
