Yor favorite closed source apps?

I avoid Closed Source apps as much as possible.

Unfortunately, however, there are no Open Source banking apps. Unfortunately, I have installed this garbage (with Sandbox Google Play Services)

I love to gamble on the stock market. My friends love Xbox, and I gamble on the stock exchange just like in Casio. Unfortunately not very good for privacy either.

freezet Google Camera

Why?
In GOS there is already a camera feature. It produces good pictures

I have two closed-source apps on my phone but neither are my favourite.

Headphones - Sony, for my BT headphones. This is required to change headphone settings. It's disabled until I need it which is perhaps once or twice a year.

PC Financial / PC Optimum. Credit card/loyality. I cash in the points for "free" groceries. Invasive as F but I can't afford to not have those points.

For Android:
Total Launcher
MiXplorer
Vivaldi
Poweramp
Flud

For MacOS:
StopTheMadness
Little Snitch
Downie
MailMate
Serial 2
RedFox AnyStream (RIP)
Transmit
Audiobook Builder

• Google Messages (for RCS)
• SMS backup & restore
• WhatsApp (gave up on converting people to signal)
• Google Drive (for encrypted WhatsApp backup since local backup attempts have been unreliable)
• Google Maps
• Google Voice (mostly use it for SMS codes and I give it out to some businesses instead of my personal line)
• Pixel Camera
• My gym's app
• vizpin smart (i'm required to have it to unlock doors and gates)
• Yahoo! Finance (real time market alert notifications and portfolio tracking)
• ComicScreen (best cbz/CBR app I've found)
• Weawow (provides dark sky weather, which breezy weather doesn't)
• Upside (fuel savings)
• Yuka (scan a food/toiletry/cosmetic product barcode and it gives a nutrition breakdown and lists additives with a breakdown about what is known about that additive)
• Streaming apps
• Google speech recognition (mostly for text to speech. I use FUTO voice for voice typing).

I'm open to alternatives for everything, I just haven't found good enough alternatives yet.

Scott thanks, I'd be looking for something for mobile though. I'm an active investor and don't want to be glued to my screen all day. So I need some sort of notification/alert to tell me that something is happening in the market or with one of my holdings and that I should stop what I'm doing to look at it. Its saved me a bunch of times. Yahoo! Finance does miss some things, but it's free and does notify me for things like announcements, earnings, major news, and large price changes. Yahoo! Finance works OK as a PWA, but I really need the notifications so I have to keep the full app installed on a profile with play services.
