Good app, but really needs Dark Mode support!

The app is very good in showing concise and accurate system info without it getting in the way, but is practically unreadable in Dark Mode. Hopefully this gets fixed in the next update.

Perfect! (plus clarification on Memory measurement “issue”)

Does exactly what I need… I’m considering upgrading some components & I wanted an easy way to check-in on performance w/o having another window open somewhere. I also typlically use >4 desktops, so it’s nice to be able to “peak” w/o swiping back to where the window is located (or pop open from Dock).

re: “Inaccurate" Memory measurements cited in other review - Not my experience. If you open the options (the “i” icon) then you can chose what you want the Memory function to measure (pressure, traditional, trad. w/o inactive). These were all pretty close to what Activity Monitor was telling me… not exactly the same, but within a small & acceptable margin. I am guessing that the other reviewer had the Memory function on “Pressure” (that was the default when I installed it), which will show a much lower (but more meaningful) % than traditional. i.e., that is why a 8GB machine will show >6 GB in use, but only register a pressure in the 35% range (see also, the red-yellow-green graphic in the Memory section of Activity Montior).

Developer Response ,

Thank you very much for adding the clarification. Our “traditional” memory view options map to UNIX memory usage. As you’ve said, memory pressure is Apple’s new way of displaying memory usage, and it may seem different to what you’re expecting.

good for the price

i’m running el capitan. the old free version of stat menus no longer works that’s why i bought istat mini. i still have a free widget for istat nano (discontinued) that works but i don’t like the widget interface. the notification area is much easier to access. i wish this listed the separate cores in the cpu display but it gives you what you need to know fast. if you want more there is always the activity monitor app. unlike the other reviewer, i found the memory reading to be accurate. it shows wired memory not app memory.
