Not an app, a site:

https://www.photopea.com/

Free Photoshop clone. For my needs, it's over the top perfect.

For me it's StreetComplete. It's like Pokémon Go, but you're doing actual map quests that help verify or correct information in Open Street Maps.

And if you do enough per month, you get free map downloads without a subscription if you use OSM the app.

I think it's only on Android though.

Syncthing, its not a recent discovery.

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.

Opener. Opens things in the app you want when iOS won’t.

Pretext. Markdown and Plain Text Editor for iOS. Simple and works. Can’t beat that.

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.

I make an email app called Port87. It’s better than any other email apps (imo), because it organizes all your email for you.

It’s still behind a waitlist, because I’m working out the kinks (damn kinky software).

This reminds me of tinyapps.org . I loved this resource in the early aughts.

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"...

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.

Insight Timer is a meditation timer with the features I like:

• timer
• intervals
• save as preset

it’s also got a huge marketplace of guided meditations, though I don’t use them

I've been using Daylio for years.

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.

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.

I geocache and some people don't know about c:geo. It's a really good app for geocaching because it has so many tools.

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

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.

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

PCAPDroid Packet capture for Android

edit: typo

Yidio to find movies and shows and where they are cheapest.

Transit to take public transit to get somewhere. It’s not designed like a typical map app.

Db meter to see if the audio around you is too loud. I use this a lot when at bars.

Onx/gaia for mapping/nav when off-roading and other recreational activities where youll be off network.

Léon URL Cleaner

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.

moreutils, especially sponge(1).

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.

sshuttle, the poor man's VPN. It creates an SSH tunnel to a remote host, and routes all traffic to a specific address or subnet through it.

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

Data Jar: When you use iOS Shortcuts this is a great way to store persistent simple data in iCloud

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!

I'm still testing them, so I can't really say "this one's the best", but here's one: https://hluk.github.io/CopyQ/
