Loopworks Measure™ Professional hearing loop measurement and commissioning, powered by Ampetronic. Overview Loopworks Measure combines a dedicated receiver and intuitive iOS app to deliver accurate, standards-based measurement of hearing loop (induction loop) systems. Designed for both experienced engineers and occasional users, the app guides you through testing, commissioning and reporting - in line with IEC 60118-4. IMPORTANT Designed for iOS 15.0 or newer, the Loopworks Measure App will not function without the Loopworks Measure Receiver R1 or R2 hardware. Hardware Requirement Compatible Loopworks Measure Receivers can be purchased from your local distributor or www.ampetronic.com R1 Receiver – supports 3.5mm and Lightning connections (via genuine Apple Lightning to 3.5mm adapter) R2 Receiver – upcoming model supporting 3.5mm, Lightning and USB‑C connections (using appropriate genuine Apple 3.5mm adapters) Measurement & Performance • Field Strength Meter (FSM), Background Noise and Frequency Response measurement (IEC 60118-4 compliant) • High-resolution digital metering (±0.1 dB) • Simple and advanced views for fast qualification or detailed analysis • Use the receiver as a loop listener, including in locked screen mode Workflow, Control & Reporting • Guided workflows for site assessment, testing, commissioning and service verification • LoopLink integration: directly connect to compatible Ampetronic C, D and T Series drivers to control test signals, adjust current and frequency response, and see instant feedback - all within the app, without returning to the amplifier • Sync results with the Loopworks platform for storage, analysis and sharing • Generate commissioning reports and compliance certificates • Work offline and sync when a connection is available • Record audio samples and access in-app guidance and support Loopworks Platform Your measurements don’t stop at the app: • View and analyse results online • Collaborate across your organisation • Pre-configure projects and test points before site visits • Generate reports and documentation for compliance and handover ## Key features - Field strength measurement - Background noise analysis - Frequency response testing - Data synchronization with online portal - Technical and certification report generation - Walk-through guides for site assessment ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/loopworks-measure/id1001040999/reviews.md ### 1/5 — Doesn’t work with newer hardware *2026-04-09* This app only works correctly with built 3.5mm jacks. With lightning it never fully calibrates and with usb-c it doesn’t recognize the receiver at all. Audio still shows up but the receiver can’t be calibrated. Ampetronic claims that usb-c support is “coming soon” which is hard to believe since Apple has been doing usb-c since 2018. Don’t waste your money on the receiver if you don’t have a ten year old iPad. ### 2/5 — Gets hung in permanent loop *2017-10-09* I give it 2stars nice idea, but it requests a yes or no to calibrate receiver if it do not detect receiver it freezes. Do I need to purchase additional add on? **Developer response:** It needs you to purchase and use a receiving device called 'Loopworks Measure R1' which is available from our US distributor. ## Frequently asked questions about Loopworks Measure ### What hardware is required for Loopworks Measure to function? Loopworks Measure requires the Loopworks Measure Receiver R1 hardware to function. This receiver can be purchased from www.ampetronic.com. The app supports the R1 with Apple lightning to 3.5mm adapters but not USB-C devices. ### What can Loopworks Measure measure? Loopworks Measure can measure the magnetic field produced by a Hearing Loop system. It functions as a field strength meter and can assess system functionality against the IEC 60118-4 Standard for Hearing Loop performance, also measuring background noise and frequency response. ### Can I generate reports with Loopworks Measure? Yes, users can create test and certification reports. The app can automatically generate technical reports from collected data, and users can also manually enter information. Commissioning reports and conformity to Standard certificates can also be generated. ### How does Loopworks Measure synchronize data? Once users create and sign in to their Loopworks account, the app automatically synchronizes collected data with the Loopworks online database when a wireless connection is available. This allows for viewing, analysis, and sharing of results online. ### What devices is Loopworks Measure compatible with? Loopworks Measure is designed for iOS 14.0 and up and supports iPhones, iPads, and iPods. It is compatible with Apple lightning to 3.5mm adapters but does not support USB-C devices. ### Is there support available for Loopworks Measure users? Yes, when using the online Loopworks environment, support is available from Ampetronic's loop experts via telephone or Live Chat. This support can assist with analysis and playback of audio samples. ### How often is Loopworks Measure updated? The app was last updated on January 16, 2025, indicating regular maintenance and potential feature additions. The latest version available is 3.2.0. ### Does Loopworks Measure have ads? No, Loopworks Measure does not contain advertisements.
