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/

Track your drivers and vehicles fleet with the aid of a fully automated intelligent system of monitoring the vehicle's driver while in traffic. Each driver will be able to create his/her own account and login or sign up to enjoy the experience of SIAMOTO app. Other components of our app are related to Map, Reporting and Account. From the Map section, the driver starts and ends a trip with the aid of intuitive buttons; the driver can also report a car crash incident which will be automatically saved in the Reporting section. In the Reporting module, the driver will be able to access a series of important information necessary for assessment, evaluation or the improvement of his/her overall driving style. This information is also available in a graphic statistical form in the Statistics / Reports section. In the Recommendations section the drivers can access all messages and recommendations sent by the system regarding their trips. All existing and concluded trips, together with all their details, may be viewed in the Trip history section. All reported car crashes, along with all other events you reported and attached images, may be viewed in the Crash history section. Check for all received warnings in the Message history section. The driver can also view all connected devices on the vehicle in the Car installed devices section. Extended training information is available in the Courses Partners SIAMOTO section.

Verdict
The clearest difference is in-app purchases: SIAMoto at none against OSpectrometer's 2. SIAMoto also leads on iOS requirement (13.4 vs 15.1). OSpectrometer's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, ads and device support there is nothing between them.
