*** Requires a corTalk® BMM1 to use. *** Contact us at 'sales1@mobiltex.com' to purchase.This app is for configuring and using the corTalk® BMM1 (Wireless Multimeter).The BMM1 is used to monitor cathodic protection parameters with accurate measurement of a wide variety of signals. This app allows access to configuration on the BMM1 and allows setting up the configuration to meet the customer's needs. In addition, the application allows collection of measurements made by the BMM1 into an internal database. The database can then be exported for use in the Mobiltex CorInsights web platform.The app allows full configuration of the BMM1 including - slot scaling and offset - input ranges - interruption On/Off/CycleOther features include the - viewing of readings - capture of readings to a database - location mapping of assets and directions to those assetsThe BMM1 is placed in pairing mode by pressing and holding the 'STAT' key until the 'LINK' LED starts flashing. The unit can then be paired with the mobile device through the CorInsights application.

- 3-axis G-force tracking
- Precision crosshair display
- Peak G detection
- Real-time chart recording
- G-force level guide
- Adjustable sensitivity

G-Force Meter+ Accelerometer shows the G-force your phone feels right now on every axis, then turns each drive, ride or run into a result you can read: press Start, press Stop, and a session card shows the peak G, the average G and how hard you cornered, accelerated and braked. ▶ Live G-force on every axis • Total G on a round gauge with a moving dot for the direction of the force • Lateral (X), longitudinal (Y) and vertical (Z) values side by side • Min, average, max and peak while you record, plus peak chips for lateral, accel and brake • A scrolling chart of X, Y, Z and total G, or a sentence that explains the current G level ▶ Stop and see the session Press Stop and a Session result card appears: • Duration, peak G and average G • Peak lateral, peak accel and peak brake • A second-by-second G trend line (the first 10 minutes of a session) • With the Car activity selected, a plain-language reading of the drive, from Gentle to Very hard, based on the peak horizontal G Every finished session is saved to History automatically (the last 20). A session shorter than 2 seconds is not saved. If you switch apps mid-session, recording pauses in the background and the same session resumes when you return, and a session cut off when the system closes the app is recovered into History on the next launch. Share a result as text in one tap. ▶ History and personal bests Open History from the top of the Meter screen: personal bests, every session with its G trend, your race runs and rolling runs. Export sessions, runs or rolling intervals as CSV. A statistics report CSV unlocks for 24 hours after a short ad. ▶ G-G friction circle A dedicated tab plots lateral against longitudinal G as a trail inside rings at 0.5, 1.0 and 1.5 G, with peak lateral, longitudinal and combined G, so you can see how much grip you used in corners and under braking. ▶ Race mode • 0-60 mph launch timing with raw and rollout times • 60-0 mph brake test with time, distance and speed shed, estimated from the motion sensors • Rolling intervals: 60-120 mph, 100-200 km/h, 30-50 mph or your own range • GPS cross-check with a GPS 0-60 time, a quarter mile time and trap speed. A good fix shows a GPS-verified badge, otherwise the result is labelled as a sensor estimate • Regen profile for electric cars: braking events sorted by their strength into likely regen (gentle) and likely friction (hard), with their maximum G ▶ Set up for your car • Dash or Holder mount, auto-level and Re-level now • Reference 1G (resting reads 1.00 G) or 0G (resting reads 0.00 G) • Display sensitivity from 0.5x to 2.0x for the live gauge; the result card always shows the true values • Activity presets for Car, Roller-coaster, Sport, Elevator and Aircraft explain what each G level means there • A Guide tab with 8 tips on mounting, reading each axis and typical G in daily life • The screen stays on while recording • Interface in 30 languages ▶ Good to know Readings come from the phone's motion sensor, so mount the phone firmly and level it before you record. Launch and braking times are estimates unless they carry the GPS-verified badge. Only drive-test where it is safe and legal. For drivers checking how smooth or hard they drive, track-day and drag-strip fans, roller-coaster riders, and students who want to see physics in numbers.

Verdict
The clearest difference is ads: CorInsights at none against G's shown. CorInsights also leads on device support (3 vs 1). G's advantage is update cadence (every 4 days vs monthly). On price, in-app purchases and iOS requirement there is nothing between them.
