May 27 2026 APP 2.0.0-beta45 has been released !
Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.
Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Hello,
When choosing a formula, for example HOO2 or other formulas: After clicking on "new formula" the HSL sliders do not change but remain for all colors on zero position. Afterr clicking on "calculate" a black image is resulted. This occurs on version 1..082, 1.083 and 2.0 beta 6. I am running windows 10.
What might be wrong?
Ralf
Hello,
meamwhile I tried the HOO2 formula on a Linux System (Ubuntu), too. Same problem:After clicking on "new formula" the HSL sliders do not change. Tried formula "default", this worked. Strange!

Thanks for notifying us, we'll investigate! 🙂
Hi Ralf @drralfwagner,
I just tested it with 2.0.0-beta6 and all is working fine in the RGB Combine Tool. HSL sliders are not present in the RGB Combine Tool, so I am not sure why you mention these. Is your problem perhaps with the HSL Selective Color Tool which has HSL sliders?
RGB Combine Tool: if I load channels with H-alpha and O3 assigned, the HOO1 and HOO2 simply work on our systems:
HOO2:
SHO4 and other formula also work fine:
Might be the reason that the sliders stay at zero (thus a black composite) that you have not assigned a channel to either H-alpha nor Oxygen-3?

Hi Mabula,
thank you very much for help. My problem was indeed that I have not assigned the channels to either H-alpha nor Oxygen-3, but to R,G and B. When assigning the channels to either H-alpha or Oxygen-3 the HOO2, HOO1 and the SHO formulas are working well after clicking on new formula.
Thanks again for your help. Now I am happy again with APP.
Ralf
