Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research. OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs. - Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values - A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen) - The whole spectrum or a specific part of the spectrum can be selected and scanned - Front camera is used to sense the reflection from the target object - Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum - The result can be saved and shared - Works offline, no need to connect to any network or internet Privacy-policy: https://software.nanorescenter.com/osprectrometer-privacy-policy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: AquaHorti at none against OSpectrometer's 2. OSpectrometer's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
