A little gem

Hobby microscopist enjoying this little app. Runs well on my MacBook too which is a bonus.
That the app shows ±λ-plate colours is a very nice feature. Would be lovely if it also simultaneously displayed ±1/4λ-plate colour swatches too!

Another great App from this developer

Beautifully executed, and very useful. Spoiled slightly by the advertisements ... Please consider charging a modest fee for an Ad-free experience.

A better Michel-Levy chart

Birefringence adds value to the classic Michel-Levy interference color chart by leveraging the intuitive interface of yor mobile device. Scientifically sound and thoroughly documented. An outstanding tool for optical petrography research and education!

***ABSOLUTELY AMAZING!***

It literally saved me! Thank you for creating such an amazing handy app. I introduced it to many of my friends and classmates and even some of my professors and they were absolutely blown away by its simplicity...I’m just kinda sad about how underrated it is. Well done!

Response from developer

Thanks so much for the review! It’s really appreciated! Andy
