(!!!) the one and only bookmark manager that works for me. why? ask my brain, i don't know.

list/grid view, folders. as for cards in grid view: only preview, page's name and site's adress, nothing more.

has both archive and trash bin. so you can move old (but still cool!) bookmarks from your view without deleting them.

multiplatform: yes quick: yes colorful: no

(!!!) widgets are EXTREMELY helpful, and there are plenty of them!

all kinds of graphs and statistics to actually see the progress. it's rewarding.

you can archive some habits if you need. they will be hidden, means less distraction.

also, you can turn on optional rest/pause days without loosing a progress. for example, making a pause with sport while you're sick. it's only fair to take your time.

it has two modes for habits: yes/no type and measured type. i like this separation. helps with priorities.

i especially love "X times per week" regime ("yes/no" type). it leaves some freedom for rest without anxiety or guilt.

plus, optional small notes for any day if you want. ^w^

multiplatform: no quick: YES! coloful: yes

suggestion from the comments: Grit Habit Tracker

looks similar, but i didn't try it: Table Habit

because i keep forgetting to take my meds. dumbass.

notifications are sticky until you check if you took your meds or not. so no accidental swapping away.

colors, icons, tags.

suggestion from the comments: Pillo

very simple and quick. i've been searching for Trello alternatives for a looong time. and i dislike complex setups.

accessible everywhere, if you have an internet connection, that is.

private and public boards! means you can share view-only pages with other people.

not colorful at all! :( only light/dark mode, except for tags. i use colorful emoji to add at least something.

multiplatform: yes (web) quick: yes colorful: NO!

as a person cursed by visual thinking, i depend on widgets. nothing on the screen? nothing to do! (kill me.)

as one AuDHD person said: "after my brain gets used to seeing something in one place for too long I don't notice it anymore. So a sticky note will work for about a week. Then my brain no longer notices it." and i agree with it. this is why changing colors and size is so important for me.

if you feel like you got used to some widget or colors, change them. make it stimulate your brain again.

and this one has 3 widgets: today's date, agenda, month view (with events). the most important part: you can resize fonts and widgets, choose colors and background opacity. helps when you need a reminder to scream in your face right at your home page. and yes, you have the whole color wheel.

as for the app itself: even more colors customization, events/tasks, different views: month, week, agenda, day, month + agenda (split view).

multiplatform: android + CalDAV quick: YES! colorful: YES!

to see how much time left! it's small and absurdly simple. not bloated, not slow.

summer: to hide from the sun. winter: to walk outside while it's not too dark.

to use together with Suntimes or instead of it. it contains more information. sometimes it's better, something it's not.

but knowing weather is good for planning anyway! :) especially info about air quality, UV index and allergens.

helps with starting an algorithm: checking the weather - picking right clothes - taking things for this weather (gloves, umbrella, etc.) - going outise.

forces me to pause with its annoying full-screen reminder! but this irritation is exactly what helps me to stop.

(!!!) customizable af. i removed recommendations and trending page. only videos from channels i follow or something i really want to find.

downloading in different formats, making a queue, playing at background, picture-in-picture, no account needed. views history back-up!

it is still in development, but already better than YT, especially UI.

standalone app, not a page in browser (where i have a temptation to check other websites). isolated environment for one certain task reduce risks of being distracted.

i honestly hate Tumblr UI, its load time, ads and login-wall. so slow, so infuriating.

remember that frog on login requirement notice? i hate it with all of my heart now. i'm sorry, Tumblr frog. it's not your fault.

though Tumblr itself is a risk, i try to not stuck there.

(!!!) posting page is simple and stripped from distractions. markdown is default, but you can use HTML elements too.

i don't like social aspects of microblogging, but i like making public text posts. also i dislike complex setups. so this thing is perfect for me.

customization is hidden in menu, which means you won't be tempted to endlessly tinkering your CSS.

cool for export/archiving if you have a website! or local copies.

multiplatform: yes (web) quick: YES! colorful: depends on your CSS

(!!!) to quickly write down something stupid at 3am.

tags and colors are helpful for balanced stimulation and categorization! i personally add emoji to the tags for better visuals as well.

good amount of text formatting: not distracting, not limiting.

multiplatform: no quick: YES! colorful: yes

honorable mention: Notally (original project).

(!!!) stimulation is balanced: colors, icons, adding pictures to notes, markdown.

widget with the short list of previous notes. optional reminders (mine are once/week), with custom description.

you can even choose a custom font from your own files! to add crazy-ass font... or maybe more readable one.

also has a cute option to make a postcard. ^w^

multiplatform: no quick: YES! colorful: yes

(!!!) again, if i don't see something right away, it does not exist for me. this rule applies for both physical and digital spaces. so i need something right on my screen!

i use it for pictures that inspire me to draw. kinda making traps for my artistic attention! :P

it's just a blank page and my words, fullscreen. exactly what i need.

multiplatform: no quick: YES! colorful: NO!

will use it 'till i die. i hate slow loading of more "advanced" code editors. perfect for simple coding. has custom color themes.

doesn't have a split view, so you need to manually update the local web page to see the changes.

multiplatform: no quick: YES! colorful: depends on your theme

grid view, folders, tags and workplaces (with optional sharing), adding images.

beware: it's discontinued, but servers still work.

multiplatform: yes quick: yes colorful: no (but my favorite color is green, so i like it)

literally the best markdown editor for android. files view, widgets, settings to add/remove tools. color schemes too!

to-do lists are buggy and strange, i don't use them here. everything else works good!

when my godforsaken hyperfixation hits, then i code (or edit code) here.

multiplatform: no quick: yes colorful: depends on your theme

interesting and random info. basically a rabit hole, but helps if used correctly.

images, colors and randomness. i can't stand gifs and short videos, but i like looking at pictures. saving them feel like collecting cool rocks.

beware of flashing lights!

visualizations for music. really captivating and stimulating.

P.S. for other (unofficial) versions and platforms check github repository.

honorable mention: old Windows Media Player visualizations. U_U
