What productivity tools do you currently use,
@Noah Hawryshko? I'm always down for bouncing new ideas around and trying new simplistic tools.
I've been playing white noise in my headphones lately, and it's helped a bunch. I highly recommend that.
I'd also be interested in learning new tricks.
Well I don't have some amazing "industry-standard" repertoire if that's what you're asking

, but I'll mention a couple more things I think are generally useful productivity-wise, along with my list-setup.
First of all there's Tasker if you have a rooted Android phone. This is great because it lets you set location-based and event-based reminders that you can't set conventional reminders for because they vary day to day.
For instance, if you forget to lock the door behind you when you come back home (yet you come home at a different time every night), you could set an event in Tasker to do action "play sound" or "vibrate phone" when condition "connected to home wifi" or "within x distance of house" is met. If you can think of a variable that is present everytime you need to do something (location, battery power, Bluetooth connectivity, anything) then you can program a custom reminder for it based off the value of that variable.
Another app I use is "f.lux" (CF.lumen on Android, root only). Multiple peer-reviewed scientific studies (PM me for said studies, not tracking them down right now

) demonstrate a statistically significant, proportional inverse correlation between exposure to 450-480nm wavelengths an indeterminate amount of time before bed and active melatonin synthesis. This is true for all colors to an extent, but exponentially more true for blue, so if you turn on f.lux a couple hours before you go to bed, it'll filter the blue light from the screen and make it easier to get more tired faster and naturally.
Also, look into ASMR quiet whisper for extra help with sleep problems. There's no hard literature to support ASMR currently, but quiet whisper tracks have a self-reported 70% success rate, which is higher than a standard placebo should be as far as non-working, self-reporting phenomenon go, so it looks respectable to me and I've personally had a lot of success with it.
