PASCO Spectrometry is specifically designed for all levels of students and teachers to integrate spectrometry into the teaching and learning of physics, chemistry and biology. Simply connect a PASCO Wireless Spectrometer (PS-2600) and insert a solution to measure absorbance, transmittance and fluorescence of solutions. The Spectrometry software specifically supports full spectrum analysis along with Beer’s law and kinetics experiments. Use a PASCO Fiber Optics Cable (PS-2601) to easily analyze the spectrum of light emissions.   Key features: • Measure and analyze intensity, absorbance, transmittance and fluorescence. • Auto-set the integration time to determine optimum spectrum • Compare multiple spectra to each other and to a set of reference lines of common elements including Hydrogen, Helium, Mercury and more • Quickly calibrate dark and reference spectra for solution spectrometry • Plot absorbance and transmittance on the same graph • Apply a linear fit to determine relationships • Determine unknown concentration based on standard curves and user feedback • Calculate inverse and natural logarithmic data with built-in calculator functions • Annotate the graph • Take Snapshots of pages for journaling and assessments Common user experience across platforms: Spectrometry provides the same user experience for tablets and computers. No matter the mix of technology in the classroom or the school, teachers and students all share the same user experience--placing the learning experience in the forefront and simplifying classroom management. Awards: • 2015 SIIA CODiE award, Best Education App for a Mobile Device (Finalist) • 2015 BETT award, Digital Devices (Finalist) for the Spectrometer + Spectrometry app Equipment and accessory: The Wireless Spectrometer (PS-2600) and the Fiber Optic Accessory (PS-2601) can be found at pasco.com/spectrometer About PASCO: PASCO Scientific brings a rich history of innovation and support for science education, with 50 years of service to educators around the world.

Verdict

The call

The clearest difference is review sentiment: Spectrometry at 100% against Relay Smart Agent's 0%. Spectrometry also leads on rating (4.0 vs 1.2) and iOS requirement (11.0 vs 15.0). Relay Smart Agent's advantage is update cadence (every 2 months vs every 6 months) and ratings volume (33 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spectrometry holds the better App Store score, 4.0 against 1.2. That said, the two scores are not equally well evidenced: Relay Smart Agent has 33 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Spectrometry's written reviews are positive against 0% of Relay Smart Agent's.

UpkeepUpdate frequency

Spectrometry ships an update every 6 months, Relay Smart Agent every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
