Great app
Good for determining how much red light you are getting.
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
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!

Free

Handy, useful tool
Useful tool to get approximate frequency of colored lights in nm
seems pretty good

Great little app!
Very handy for demonstrating, or determining, the wavelength of a given colour and so easy to use. Would be ideal for use in the classroom and a lot cheaper than spectrometer!
Also, I contacted Björn with a technical question and he was extremely helpful and prompt in his replies. Great guy!
