Web Video Caster is probably my most used app. It casts just about anything to just about anything. It's worked better than anything else on my Chromecast and when I've needed to connect to Roku.
It supports IPTV, playlist creation, bookmarks, watch history, recent played, resume from last position, and a ton more.
The dev has been great whenever I've reported bugs and has added a few requests over the years.
Too Good To Go has been awesome since I heard about it on How I Built This. It's designed to reduce food waste, but I think that makes it sound less appealing than it is.
Participating eateries estimate how much product they will have to throw out at the end of the day. It's not bad stuff, but stuff they made too much of. Instead of tossing it, they set it aside, and you come take it for pennies on the dollar. No extra work for them, cheap mystery box of eats for you.
We've tried many fancy local bakeries we couldn't really afford, tried new local pizza places, got some great frozen treats and an ice cream cake from the premium ice cream place, and some great Jamaican takeout from a place near my work that'd normally be out of the way.
We also stock up on bagels from the Manhattan Bagel. They're normally around a dollar each, but we get 15-18 for $5 and then we freeze them. Been doing that for months now, saving a ton of money. Sometimes we get misshapen ones, it flavors we don't really like, but we still come out way ahead, or we learn different ways to use things, like the salt bagels we didn't originally like.
Traffick Cam: Help combat sex trafficking by uploading photos of hotel rooms from your travels
Traffickers regularly post photographs of their victims posed in hotel rooms for online advertisements. These photographs are evidence that can be used to find and prosecute the perpetrators of these crimes. In order to use these photos, however, investigators must be able to determine where the photos were taken.
Pocket Bard is great for setting adaptive music in D&D sessions. Pick a setting (town, cave, woods, dungeon, etc.), choose the activity the party is doing (exploration or battle), choose an intensity. The music will automatically adapt and fluidly change to match the situation.
I'm recently enjoying walkscape, which is an RPG where you have to walk in real life to progress in game activities, such as crafting or fighting.
It's in closed beta, but you can sign up for the next wave of beta invites and I got in pretty fast
Also, I downloaded streetcomplete but haven't really gotten around to it. It's an app where you map out your surroundings for open source maps with Infos, like opening times at a bank or the width of the street or the type of road, etc. A cool concept, but I always forget about it
URL Check It acts like an intermediary to open in browser when you click on a URL. Its useful to kinda look at the URL before it opens and choose browser.
Audio Share Relays audio from PC to mobile through network
I got a couple of apps I'd recommend in a heartbeat.
Spectdroid is a spectrogram app. Its unreasonable how often I'm using this app. I got some mild tinnitus that comes and goes and this app allows me to find out if I got some actual weird buzzing I'm the house or if it's just in my head.
And LocalSend is an amazing app for sending files between various devices and OSes over a local network. I no longer need to set up file shares, plug in my phone to a computer, or use cloud storage just to transfer over some files.
It's designed to track moods and the activities associated with them, but it's adaptable, so I use it to track my headaches. It's very easy to use and it doesn't feel onerous to record the information.
My partner introduced me to the Dutch "112" app (112 is the emergency telephone number in Europe).
I hope I never need it of course, but if I do it automatically shares my location and it allows me to chat instead of call if I would be in a situation that requires that.
Also, I really enjoy Jepster as my biking computer when cycling. The guy that built it is also very approachable when you find a problem, which is great.
And when you're planning to get kids have a look at "Kinder"...
Edit: and not an app, but a website: Pairdrop - really useful for cross-platform file sharing, especially when you just need to email to colleagues something you snapped with your personal phone, but yoe have overly tight IT systems in place at work that stop you from connecting your personal phone to your email or OneDrive.
For anyone looking to play Super Mario Sunshine and wants to consider 100%, there's "Blue Coin Tracker".
Not only can you check off what you've found, but it's got screenshots, descriptions, and strategies to help you find it. Even links to YouTube clips if you're still stuck!
It's invaluable. The blue coins are pretty evil in that game.
It's a simple app that strips extra unnecessary details like tracking tags from copied URL links. Highly recommended for sake of privacy, plus the cleaned links are shorter and tidier.
Trail Sense, it's all the "survival" tools in one great package. Do I use it often? No. Does it feel like unwrapping my favourite toy every time I open it? Absolutely.
kinder world, it's a plant-watering emotions-thinking about game that's a cover for a mindfulness app. really effective because cute animal characters.
For iOS/mac, I love the Vinegar extension. It’s great for stripping YouTube down to just the video, provided you use Safari instead of the YouTube app. It also regularly updates. Yes, I know there are free ways to do this (it’s $1.99), but this is more about convenience and supporting a dev.
It's a ridiculously versatile granular sampler synthesizer. Obviously not for everyone, but it's super fun to just make weird soundscapes with. Even with just your phone mic.
Unified Remote. It's a little janky, but it does you to turn your phone into a trackpad and/or keyboard for your phone. It works with swipe typing, and allows you to use keyboard shortcuts such as Alt+Tab or Win+Shift+Arrow.
Truly the best way I've found of using my PC from my couch.
ShareWaste. You can sign up that you have a compost pile or chicken to feed, etc, and people with food scraps can find places to "donate" to! I have 3 or 4 regular contributers to my compost pile!
ChildIDFile. Creates a secure file of your kid's information that lives only on your personal device but can be shared with police quickly. Hopefully you never need it
These have been around for quite a while, but I recently learned about clipboard managers. I haven't met someone who uses one, perhaps because it is an inconspicuous tool. Regardless, I love being able to quickly paste text that I use frequently!
Chafa - I can turn pictures in ANSI art for my terminal
Syncthing - A godsend for me and I can't believe how easy it is to set up and have it just work, I was almost disappointed when I was setting it up expecting issues and then the mf just works perfectly fine without issue
Tailscale - Very useful to remotely ssh to my computer(s) even from my phone
Termux - terminal on android
This one you may have heard of and it's not exactly niche, indie or small but I'll add it anyways just in case:
Too Good To Go - allows you to get cheap food and save it from going to waste. I use it a lot when I can't go to the university cafeteria and don't feel like cooking
