Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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.
Hi,
I observed a strange effect which might be a minor bug or a non-issue:
Running a full stacking process, the RAM usage of ARR ramps up while Analize Stars process, lowering below 16GB for APP afterwards. However, the OS RAM usage display ramps up during Normalization until it reaches the ceiling (64GB on my computer), while APP usage remains below 16GB. Strangely, the CLEANER PRO APP is showing only half the memory is used in total (around 20-30 GB). See below screenshot, in the menu bar to the right.
So which RAM usage exactly is indicated by APP? -
My suspicion is, SWAP memory on the "Flash SSD" is being used by APP which seems to be a black hole for APP's counter - only stored information is counted but not if any of the SWAP is reliefed again.
Having said that, even while operating in the "red zone" through half of Normalization and all Integration stages, APP behaves normal, without slowing down up to the very end of the process. It' just a bit loosing control on what's going on actually.
I am running MacOs 12.4 on a Mac Studio with M1 Max & 64 GB RAM
APP now uses up to 98% of the available memory. I guess it determined here it would need a lot during the process, let me ask Mabula for specifics.
Hi Jochen,
The memory that APP is claiming is the 10082 MBs number out of a possible 57096 MBs. The RED numbers for your OS indicate that the OS as a whole is consuming a lot possibly to other tasks/applications on your operating system?
What is macOS reporting for memory usage for APP at such a moment with macOS system monitor ?
Mabula
Hi Mabula,
the strange thing is, APP was the only major Applicatio running, additionally I had just minor surveilance Apps like TG Pro (fan control), Cleaner Pro running idle. These, without APP do not use RAM extensively. Even when APP was indicating 98% for APP and 100% for OS, the total amount used seemed to be just 31% as indicated by Cleaner Pro - which might translate into the RAM amount used by APP actually. Also, I recorded processing speeds and I couldn't see any hint of a slowdown which would be expected in RAM overload phases. I may provide You a high-level protocol of yesterday's stacking process, including temperatures, fan speeds and time stamps (I was just nerdy-curious 😉

Hi Mabula,
here is a snapshot while Normaliztion:
APP RAM is indicating 22 GB while Activity Monitor is pretty much in line with 21GB for APP. However, OS read is already ramped up to some 64 GB in APP and I think I know why: in Activity Monitor, I could see a high amount of Cache used (34 GB) and a lot of Compressed Memory 45 GB, but 0 Swap. You can also see the CPU cores loaded nicely in the graph, with the GPU cores idle around 10% Avg. or 25% burst load.
Hope this helps,
Jochen
Hi Jochen @jochen-scharmann,
So nothing is odd then. APP is reporting the same memory consumption as is macOS.
What macOS is doing besides that is on the operating system level and completely out of our control of course. If it is data for cache that consumes the memory on OS level, I would not be concerned, because it would be released if another application really needs it 😉
Mabula
Thanks Mabula, I agree...
what puzzled me is that I never saw the "OS" RAM usage ramping up to 98% on my old Intel i7 Mac...
I am not sure if it helps to count in the cache size, as cache usage is just temporarily and would be reliefed as You said. Ideally I would expect APP to display just "real" RAM usage in total. If you watch red letters@100% it's hard to tell yourself it's nothing to worry about 😉
Thanks again for Your great support!
Jochen
