Using the Echo Meter Touch 2 Pro plug-in module, this app allows you to listen to record and automatically identify bats by their ultrasonic echolocation calls. The module and this companion app reveal the silent and often times invisible world of bats, providing outdoor enthusiasts, citizen scientists, and researchers an affordable and informative way to interact with these important creatures. There are two models: Echo Meter Touch 2 (EMT 2) is intended for nature enthusiasts and batting hobbyists and Echo Meter Touch 2 Pro is designed for bat professionals and features a higher quality microphone, adjustable gain, and higher sample rate. The Echo Meter Touch Ultrasonic Module senses ultrasonic signals, digitizes the signal, and transmits the ultrasonic data to the app on your iOS device. LISTEN TO BAT’S ECHOLOCATIONS EMT2 translates bat echolocations into frequencies that are audible to humans using two technologies. Wildlife Acoustics’ patented Real Time Expansion (RTE) allows you to listen to bats in real time with unparalleled fidelity. RTE maintains the timing and tonality of the original echolocations. Heterodyne (HET) listening via manual and automatic tuning is also available, for those accustomed to that way of hearing bats. VIEW THE ECHOLOCATIONS ON A SPECTROGRAM A real-time spectrogram shows the frequencies and timing of the echolocations. Scroll back in time and zoom in on previous "bat passes." SEE MOST LIKELY BAT SPECIES IN REAL-TIME*** The Auto ID feature analyzes the echolocation calls and suggests the two most likely bat species matches in real time. This is the same technology used in our professional Kaleidoscope Pro Bat Auto Identification software. Currently, the app can identify 26 species in North America, 25 in Europe and 57 in the neotropics. For more information on Kaleidoscope and a full list of species, visit our website. RECORD .WAV FILES Activate triggered recording mode to automatically save bat passes to full spectrum .wav files for analysis on a computer or to view on your iDevice. Or use manual record mode to control start and stop of recording. View the recording spectrogram and add voice or text notes. Listen to the recording using RTE, HET, or traditional Time Expansion Playback (playback at fractional speed to make the ultrasound audible). SEE YOUR PATH AND RECORDING LOCATIONS View in satellite or road map view. View identified species codes directly on the map. Go to the recording's spectrogram from the map view. Transfer to your computer to view in Google Earth. Your iDevice must have GPS capability or you must use a Bluetooth GPS receiver for this functionality. *Continued use of GPS running in the background can dramatically decrease battery life.* TRANSFER RECORDINGS TO YOUR COMPUTER The EMT 2 can transfer the .wav recordings to your computer over a Wi-Fi network or using a USB cable. SHARE RECORDINGS VIA EMAIL OR MMS MESSAGING And import and open files that have been shared with you. ***Because bats vary their echolocation calls in response to a wide variety of needs, no automated identification can achieve 100% accuracy in species identification. Auto-ID, though largely accurate, should not be relied on as a basis for scientific research. Auto-ID is intended for use in analyzing recordings of single bats in free flight in low clutter environments. Auto-ID will not work well on recordings of roost emergence, multiple or captive bats, bats in high clutter environments, or bat social calls. Auto-ID does not include every possible bat for each of the covered regions.

My wife got me the Echo Meter Touch 2, so I downloaded this app (iOS version) and have used it to find and ID bats all over the western US and in Costa Rica. It is so much fun and really easy to use. I highly recommend it! ### 5/5 — Great app with good tutorials *2026-08-02* So cool to find bats in my neighborhood. I never knew ### 5/5 — STUNNING BIT OF KIT *2026-07-27* I have used my Echo meter all over the place and is an absolutely fantastic bit of kit, well worth the money, easy to use and set up. ### 1/5 — I can see many bats flying around but tge detector can not identify any *2026-06-20* I first purchased this device about three years ago and was very pleased with the performance but now even after downloading updates it appears go be unable to identify any bat signals. Very disappointing! ### 1/5 — Misleading… *2026-05-24* An absolute waste of effort; seems app does not function unless you purchase a device through the app for $149. Very disappointing 😢 ### 5/5 — Love this app *2026-03-11* It’s like having a magic little device that lets you enter the world of the little bats once it hits twilight. I had to wait an extra day once it came in because the weather had dropped below 50°F here and I knew the bats would be in torpor, but the next day I got out and identified so many different species right in my backyard. It even amplifies the sound so that you can hear what they might sound like at a range you can hear and understand and it’s just really amazing. The app is very easy to use as well. I do wish it would identify the bats whether you were recording or not, but it’s a small downside for the very many ups the app has. ### 4/5 — Idioma *2026-01-25, version 3.1.2* A ver, para cuándo traducción al español ### 2/5 — Unusable *2025-10-11* Unfortunately I actually have the echo meter (it was a gift), but they no longer make the echo meter for apple phones and none of the third party adapters work :( so I have the meter and app, and can’t connect them! super frustrated that they stopped making for apple. We tried everything and even went to the apple store because we thought we needed brand-name adapter - but apple doesn’t make usbc to lightning adapter :( bummed ### 1/5 — !! Do not update to Version 3.1 !! - Missclassifications of bat species *2025-08-24* The previous version was great, I had very few complaints and would have given 5 stars. But the update has made the app nonfunctional. All species are missclassified. E.g a call of a horseshoe bat is mistaken for a soprano pipistrelle. No human who has a bit of an experience would ever make this mistake due to the distinctly shaped calls of horseshoe bats. All other species are also mixed up (common pipistrelle mistaken for northern bat, northern bat mistaken for noctule …). Do not download the new version! This needs to be fixed asap. ### 5/5 — Working great but now broken *2025-08-24* I use this app a lot and it’s great. However an update was released yesterday and now the app won’t open. Please fix ## Frequently asked questions about Echo Meter Touch Bat Detector ### What does the Echo Meter Touch Bat Detector app do? The app works with the Echo Meter Touch hardware module to allow users to listen to, record, and automatically identify bats based on their ultrasonic echolocation calls. It translates these calls into audible frequencies and displays them on a real-time spectrogram. ### What are the key features of the app? Key features include real-time listening to bat calls using patented technology, viewing echolocations on a spectrogram, automatic identification of likely bat species, recording bat passes as .wav files, and mapping recording locations. ### Is the app free to use? The app itself is free to download and use. However, it requires the Echo Meter Touch hardware module (sold separately) to function. There are two models of the module available, with different features and price points. ### What devices is the Echo Meter Touch Bat Detector app compatible with? The app is designed for iOS devices. For location tracking features, your device must have GPS capability or you must use a Bluetooth GPS receiver. Continued use of GPS in the background can impact battery life. ### Who would benefit from using this app? This app is ideal for nature enthusiasts, hobbyists, citizen scientists, and professional researchers who want an affordable and informative way to study and interact with bats and their ultrasonic vocalizations. ## Version history (last 5 releases) ### 3.1.12 — 2026-08-07 +Adds a menu item on the Information screen to create an app debug log to assist us in understanding and fixing app issues. ### 3.1.11 — 2026-06-26 +Several bug fixes. ### 3.1.10 — 2026-06-09 +Now allows playback through Bluetooth devices.
