Hi guys,
I'm making the switch from Android to iOS (iPhone 7 Plus). Only thing I'm worried about is losing some of the rooted/custom ROM features, specifically:

1. system-wide hosts-based ad blocking (ex. Adaway)
2. system-wide firewall controls (blocking internet access (both WiFi & celular) to apps)
3. hiding jailbreak/root from Banking apps (ex. Magisk Hide)
4. double tapping status bar to sleep
5. estimated time till full when charging on lockscreen
6. brightness control gesture (swiping finger along status bar controls brightness level)
7. Bluetooth battery status (showing battery level of connected non-Apple speakers/headphones)
8. show alert for call waiting
9. volume buttons control media volume not ringtone/system
10. grouped notifications, not the chronological notifications of iOS
11. screenshot type (full/partial)
12. hold power button when screen is off to turn on torch
13. modded WhatsApp (ex. WhatsApp Pro: appear offline feature specifically)
14. modded Youtube (ex. Youtube Vanced: no ads, background playback, setting default quality)
15. Call recording
16. System-wide theming (ex. Substratum: I remember Winterboard from back in the day)
17. system cleaning tool (ex. SD Maid)
18. sound profile adjustment (ex. Viper4Android)

Which of these, if any are possible on a jailbroken device? If so, what tweaks do you guys recommend for these features?
Thank you in advance!

Hello Apple users,
first of all I'd like to mention that I have never owned a MacBook but I was an iOS user from late 2010 to late 2015, when iOS was objectively better. Late 2015 I switched to Android as I've felt Apple stagnated and Android was catching up/surpassing iOS. There are a few reasons why I am thinking of switching back.

1. My problem with Android/Google

I feel like Google doesn't know where it's going..
the Pixel line is a failure 4 Generations in, the nightmare of ad- and malware that is the Playstore, I don't know WTF they were thinking with Stadia, updates are still a mess considering android as a whole and overall after 5 years android is still way too fractured, in a bad way.
Samsung is trying way too hard with forcing their own non-removable software down your throat along Googles already pushy attitude regarding android becoming more and more cluttered with proprietary software (yes, I am one of those crazy people who like to use Open-source software if possible, since I don't want to trust random companies to data mine me). And yes Google data mines like crazy but it's getting worse and Android phones are getting more and more expensive.

2. I hate Windows

Let's be real here, no Microsoft I don't want Candycrush constantly installed on my Workstation. The only reason why I was able to endure the absolute cesspool of what is Windows 10 is that I mostly live in apps, where Windows doesn't shine through a lot and even then I want to delete Windows 10 at least a few times per week. Another big reason why I managed to get by so long is that, whenever I can, I tend to use Linux. However, Linux has its own issues in terms of directions and how fractured it is, not even getting into lack of widespread software which doesn't have a real Open-source alternative.

3. I want to get back into Drawing/Art

Which brings me to tablets and digital Art, which brings me to the conclusion that the new iPad Pro's have no competition, which means I'd have to get at least one Apple product regardless. (I don't want to get something from Wacom etc. as I want it to work without a PC/Mac)
Those are not all reasons I want to/think about switching but listing all would take too long and those are most of the main ones anyway.

What holds me back? (Android Apps)

The few things that hold me back are, of course, Apps. Most of them are Open-source and/or not available on iOS.

1. MoneyWallet (Personal Finance App that I use extensively)
2. AndOTP (Authentication)
3. KeepassXC (Password Manager) Very important
4. YouTube Vanced (vanilla YouTube is unusable due to amount of ads)
5. Xtra (Twitch equivalent of YouTube Vanced)
6. Tachiyomi (Manga reading app)
7. New Pipe (Open-source YouTube client)
8. Torrents (for downloading Linux ISO's)

I've searched around a little bit for alternatives but most require jailbreaking (which I don't want to do necessarily) or using something like Tweakboxapp which I'm not sure about how safe they are... As for torrents, I haven't found anything reliable on iOS which sucks.
My Ideal setup would look differently, I would like to use complete Open-source Android on a good Phone and tablet + Linux on my Laptop but in reality it is not feasible, they are just too fractured.
So my only choice with full working cohesion that is streamlined over multiple devices is Apple. If any of you guys know about reliable alternatives/iOS equivalents for the apps I have listed, please tell me, thanks! (if they are Open-source the better!)

TLDR;

Android is starting to annoy me, I hate Windows and I have to get an iPad Pro anyway so might as well switch completely to Apple. A few apps are holding me back from switching, if you know any reliable alternatives please tell me, thanks!

These are the things I can do in Android that I *think* I might not be able to do on a jailbroken iPhone 11 Pro (or a stock one). Some of these things might even be possible without jailbreak, I am not sure. But I think y'all are experts so let me know if I can do these things :)

1. I use YouTube Vanced which blocks ALL ads so I NEVER have to watch an ad on YouTube ever again. On top of that, I can play videos in the background while browsing through other apps on my phone (so only hearing the audio), and also continue playing videos while the phone is locked (audio only obviously). So essentially, I can throw on a YouTube video, lock my phone and go for a drive. I know this is a paid feature but I get this for free on Android with ease. I heard iOS has YouTube++ or something. Is there a solution for me here?
2. Android has a system-wide feature called Private DNS where I can use a specific dns (dns.adguard.com) which blocks almost all ads system wide = i.e. no ads while browsing the net, no ads while playing games, etc. The only place I get ads is IG/FB/Snap. Can I do sometthing like this in iOS or another way to block ads?
3. How easy is it to Chromecast things from an iPhone? (sorry this might not be a specific jailbreak question) I have quite a few Chromecasts and many apps that I would chromecast from (e.g. Youtube/Youtube++, TV streaming apps, Netflix, etc.) is it flawless or buggy? I won't buy an Apple TV.
4. I use a "Secure Mode" to store things in a separate space completely, and it is protected by biometrics. Here I can have an individual set of apps like Chrome, Contacts, Phone, Social Media apps etc. Is there a possibility of having a secondary secure individual app-space on an iPhone? Think of it as almost a 2nd phone on the same phone! A hidden life :P It's very useful when you want to separate work and personal life. Or any other use you see fit.

General Qs:

1. How much does jailbreaking affect battery performance?
2. How much does jailbreaking affect phone performance?
3. Is it currently easy/stable to jailbreak an iPhone 11 Pro?
4. What are some cool things you can currently do on a jailbroken iPhone? Any suggestions?

Also, a lot of the time I've asked questions to iPhone users like this, they just hit me with the "well go with another Android then, buddy". Don't want to hear that, I genuinely am interested in the iPhone 11 Pro now :)
Thank you!
