SensorCheck™ vs Epoch Cloud
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SensorCheck™
This app, when paired with a specific diagnostic tester, compares marine transducer performance against factory specifications. It accurately tests a wide range of frequencies and automatically generates test reports that can be shared. Technicians can also use it to submit warranty information.
- Compares transducer performance to factory specs
- Tests traditional and CHIRP-ready transducers
- Supports frequencies from 10 kHz to 500 kHz
- Automatically reads XducerID® features
- Generates and shares test reports
- Enables warranty information submission

The AIRMAR SensorCheck™ App, paired with the TDT1000 Transducer Diagnostic Tester, compares the performance of a transducer in the field to its original AIRMAR factory specifications. Simply install the SensorCheck™ app on your Bluetooth LE-enabled smart device, connect to the TDT1000, and get started! Accurately test both traditional and CHIRP-ready transducers that operate at frequencies ranging from 10 kHz to 500 kHz. With CHIRP-ready models and any traditional models 1kW and above, the TDT1000 will automatically read XducerID® features, such as transducer model, frequency, part number, serial number, total run time, and maximum internal ceramic temperature. When the test is complete, an IN RANGE or OUT OF RANGE determination is made and test reports are automatically generated. Results can be emailed or texted directly to the boat owner or an AIRMAR technician. SensorCheck™ enables technicians to automatically submit warranty information to AIRMAR. The TDT1000 kit includes test unit, TDT Test block, power supply, break-out box for bare wire transducers and carrying case. Additional OEM Test Cables required (sold separately).

The Epoch Cloud APP is specifically designed for Epoch Cloud batteries and supports information monitoring of individual batteries, as well as battery systems in air connection or wired connection, etc. You can also easily realize the Bluetooth function of the batteris by connecting the Bluetooth module for more comfortable and convenient user experience. Make sure you have the latest app version. Turn on your Bluetooth. Tap the icon to open the App. It will search for all Epoch Cloud batteries within the range of your Bluetooth device and provide a list. If all the batteries are not listed, move closer to the battery location and refresh the screen. Choose the battery you want to look at. The Epoch intelligent battery management system and the active equalizer are connected via Bluetooth to monitor the battery status, collect, store and process information during battery operation in real time, exchange information with external devices, and solve the safety, usability and usage of the lithium battery system. The key issue of life is to extend the service life of the battery to a certain extent, and to enhance the stability of the battery pack to a certain extent. 1. Display real-time SOC, voltage, current, capacity, temperature, and other parameter values, and display them in the form of instrument panels and numbers; 2. Display the real-time voltage and alarm status of all single batteries. If the reported parameters trigger the alarm value or protection value, an alarm will be prompted; 3. Cell temperature warning. Real-time alarm for over temperature, over current, over voltage, under voltage. 4. Record the warnings/protection that occur at each moment. Best Regards!

Verdict
The clearest difference is rating: SensorCheck™ at 3.8 against Epoch Cloud's 2.6. Epoch Cloud's advantage is review sentiment (33% vs 0%) and update cadence (every 3 weeks vs every 3 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SensorCheck™ holds the better App Store score, 3.8 against 2.6. Both are backed by a comparable volume of ratings — 6 and 5 respectively. Written reviews complicate that: 0% of SensorCheck™'s written reviews are positive against 33% of Epoch Cloud's, so the app with the better star average is not the one people write more warmly about.
SensorCheck™ ships an update every 3 months, Epoch Cloud every 3 weeks. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
