Application displays data from Theta-Meter devices (Wi-Fi and Bluetooth 4.0BLE connection) which measures human body galvanic skin response. Skin conductance, also known as galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR) or skin conductance level (SCL), is a method of measuring the electrical conductance of the skin.
HATO ONE
This utility app measures key light aspects crucial for poultry welfare and performance. It allows comparison with industry standards and export of data for analysis. Remote measurement capabilities enhance user convenience.
- Measures light intensity
- Measures critical color temperature
- Measures light spectrum
- Measures color rendering index
- Measures light flicker
- Compares measurements to standards
- Exports data to PC
- Remote measurement

The HATO ONE is an all-in-one light meter. A must-have for every poultry specialist who is aiming to improve animal welfare and performances by means of lighting. This product is able to measure all key aspects of light that matter for poultry: • Light intensity • Critical Colour Temperature • Light spectrum • Colour Rendering Index • Light flicker After measurement, the HATO ONE enables you to compare specific measurement results with poultry needs, human needs or other lamps on the spot to directly allocate points of improvement. All measurement data can be exported to a PC for further analysis as well. The results after measurement can immediately be seen at the HATO ONE App. Furthermore, the HATO ONE APP makes it possible to measure from a distance, so you don’t have to keep the meter in your hands all the time. Improve performances, start measuring! More information? www.hato.one

Verdict
The clearest difference is review sentiment: Theta at 100% against HATO ONE's 0%. Theta also leads on rating (5.0 vs 2.0) and update cadence (monthly vs every 8 months). HATO ONE's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Theta holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: HATO ONE has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Theta's written reviews are positive against 0% of HATO ONE's.
Theta ships an update monthly, HATO ONE every 8 months. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
