User reviews

Great app

Good for determining how much red light you are getting.

Response from developer

Thank you, drpj! I’m glad you find Light Spectrometer useful for checking the red-light levels around you. I really appreciate the 5-star review.

Warning - automatic payment

App automatically debits your App Store account after a few weeks without even requesting your permission. Even if you’re not using the free version of the app!!!

Thank you!

This is a great tool … it’s spot on … I use it to see if the product actually is what they say it is with regards to light therapy. Love it!!

Response from developer

Thank you so much for the kind words! Really glad the app is proving useful for verifying light therapy products and that the app is spot on! Reviews like yours mean a lot to me as a solo developer. Happy measuring! ☀️

Abzocke, Zeitverschwendung

Bei den Suchergebnissen steht kein Preis damit es so aussieht als wäre es kostenlos

Response from developer

Wie in der Beschreibung angegeben, ist die App für einige Wochen kostenlos nutzbar (tippen Sie einfach auf „Schließen" beim Zahlungsbildschirm). Wenn Sie sie mögen und weiterhin nutzen möchten, ist danach ein Abonnement oder ein einmaliger Kauf erforderlich. Falls Sie nicht genügend Zeit hatten, die App ordentlich zu testen, wenden Sie sich an apps@contechity.com und ich verlängere gerne Ihren Testzeitraum! Vielen Dank und Entschuldigung dafür!

FAQ

What does the Light Spectrometer app do?

This app measures the light spectrum to determine the dominant wavelength in nanometers (nm), frequency in terahertz (THz), and period length in femtoseconds (fs). It is designed for analyzing colored light sources and providing real-time measurements.

What are the key features of this app?

Key features include high accuracy, real-time measurement, measurement of wavelength in nm, frequency in THz, and period length in fs. It also allows users to save measurements with notes, supports many languages, and offers optional calibration for enhanced precision.

Is this app free to use?

The app is free to download and use, but it offers in-app purchases. These purchases may be for features like calibration or other enhancements to the measurement capabilities.

What are the limitations of this app?

Smartphone cameras have inherent limitations in distinguishing very short or very long wavelengths. Accuracy may be limited below 465 nm and above 610 nm due to physical camera sensors. An automatic warning appears on the screen for these wavelengths.

Can I use this app to measure white light or the color of surfaces?

This app is not meaningful for measuring white light as it consists of a wide range of wavelengths. It is made for measuring colored light. For measuring the color of a surface or material, you would need a different application like a Colorimeter Camera Color Meter app.
