nRF Edge Impulse app is developed in collaboration with Edge Impulse to train and deploy embedded machine learning models on the Nordic Thingy:53 using Edge Impulse Studio. Every Nordic Thingy:53 comes pre-installed with firmware compatible with the nRF Edge Impulse mobile app. The app allows you to upload raw sensor data via your mobile device to the cloud-based Edge Impulse Studio and deploy fully trained ML models to the Nordic Thingy:53 over Bluetooth® Low Energy (LE). The app allows you to choose between existing projects in Edge Impulse studio data or creating a new project and can collect sensor data from the following set of sensors on the Nordic Thingy:53: - Accelerometer - Microphone - Magnetometer - Light - Temperature, Pressure, Humidity and Air quality - Inertial (Accelerometer and Magnetometer) - Light and Environment - Light and Inertial - Environment and Inertial - Light and Environment and Inertial The collected sensor data can be labeled as training or testing data and may be inferenced directly in the app with machine learning model deployed to the Nordic Thingy:53. A free Edge Impulse account, which may created from the app or at www.edgeimpulse.com, is required to connect nRF Edge Impulse with Edge Impulse studio.

Verdict
The clearest difference is review sentiment: Secure Terminal at 86% against nRF Edge Impulse's 0%. Secure Terminal also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (62 vs 3). nRF Edge Impulse's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Secure Terminal sells 1 one-off in-app purchase. nRF Edge Impulse asks for nothing beyond the download.
nRF Edge Impulse holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Secure Terminal has 62 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 86% of Secure Terminal's written reviews are positive against 0% of nRF Edge Impulse's, so the app with the better star average is not the one people write more warmly about.
Secure Terminal ships an update every 3 weeks, nRF Edge Impulse every 3 months. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
