spasypaddy Got to be honest here, can’t say if it has “better” features as I have never used an Ikawa. Currently I don’t think you can use a smartphone app on it - all adjustment of profiles would be done on a desktop/laptop, which personally suits me better. I have not played about with the software, however Kaffelogic do have in-depth tutorials on their website: https://kaffelogic.com/community/viewtopic.php?t=153
Have not really answered your question, but I have only just started using the Kaffelogic, so it would be unfair to say too much until I have used it for a good few months. Most important thing are the results in the cup - I roasted a Sidra natural yesterday and tasting it this morning - I can honestly say it is pretty much on par with some of the “best” coffees I have tried. All subjective of course, but for my first few roasts I am very impressed with the results and the coffee tastes good. That’s what matters most for me.
I guess it just comes down to choice, personal preference and possibility of future upgrades - my understanding is that Kaffelogic are working on a BOOST package as a future upgrade, which will increase the capacity (200grams instead of 100grams is my understanding) and an upgraded chaff collector. The current chaff collector is functional and works, but feels a bit flimsy on top in my opinion.
