Great app
Response from developer
Hi, thanks for being a long time customer. BTW, we are coming up on our 12th birthday thanks to folks like you. The short answer is no you don't have to pay for existing functionality. When you purchased the app, the compare function was triggered by an icon the looked like a scale or balance. Now the compare function is accessed by a more legible icon. It is found at the bottom left of the gel view screen. The in app purchase is to view gels or photos through the camera much as you would look through a swatch from your gel book. Roughly 1/3 of our customers have added that functionality .
Almost Perfect
Also once you add a gel to a project, you should be able to click on those gels and see the waveform and transmission %. Not just attached notes.
Fix those two things and you’ve got a 5 star app!

Thanks, we appreciate your comments. You can cross compare any 2 gels in the library. Just select the first color and then tap the compare icon at the bottom left and that will allow you to find any other gel in the more than 1600 colors. We will take a look at your request for projects and see if it can be done soon. BTW, the twelfth birthday for our app is coming up and we would love to get another star for our rambunctious 12 year old.
