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.
It does vary by day and location, but the surprise is part of the fun. I'm between suburb and rural and there's a decent number of choices, and new things get added with some regularity. It also makes it fun to use while traveling.
I thought this is also a nice one to recommend here as it actually started as a European app, so it's nice that it's not US only, so non-Americans may actually have better luck for a change.
I wish Too Good To Go was in use in my city. My friend lives in Oakland and she uses it all the time. She said it's a bit hit-or-miss, though. She's shown up at some places and they're like, "here's a bag, fit it up with whatever and we'll charge you $n for it." Once it was a shelf of stuff and they said she could as much stuff as she wanted from the shelf for the same price. Once when I was visiting her, we got a huge bag of baked goods. If nothing else, it can help familiarize you with areas and businesses you may not have come across otherwise.
The bagel place is like that sometimes where they haven't made the buzz yet and they let us pick. The Jamaican place has seemed the same every time, but it's a great portion of assorted items. We also got good stuff from a vegan, non-every allergen place. The prices were premium, but the stuff was really tasty, and even though we didn't have special diet restrictions, other family members do, do we could promote it to them. We've also gotten to try different things we don't normally order, like we get a big bag of pepperoni rolls from a pizza place, and the other place is the sausage food truck thing outside Home Depot which was actually really tasty.
Only once did we feel a place was a little less generous, but it still wasn't a bad deal for the price, just in comparison to other grab bags.
It's got us to try both local stuff we've never gotten to check out, and also things a little further away than we'd normally go to because it's a cheap adventure with really nothing to lose.
