SignTools VS ntfy

check this out https://github.com/SignTools/SignTools (personally haven't tried it)

There are two components to self-hosting SignTools, the web frontend, and the actual signing server, the latter of which must be run on macOS. Fortunately there's a guide to set it up so that you use GitHub Actions as the signing server, which gives you a certain amount of free minutes per month. I've never gotten close to the limit, even when I'm signing a few dozen apps. The guide also shows you how to set up the web frontend on Railway, which also offers free monthly credits, so you can actually self-host both components for free: https://github.com/SignTools/SignTools/blob/master/INSTALL-SIMPLE.md

SignTools (it's nice for developers with Apple Developer Accounts), for regular users it's kind of a hustle

The SignTools developer (tool that I used to sign other apps with working push notifications) said this about the document posted above:

im new to this i used to use appdb but i kept getting revoked so now i got a dev account for me to make apps and also use it to sideload idk what app to use , i saw some people talk about SignTools to get notification is there any other way to get notification other than that app? i only use it for cercube and rocket insta so please help

Keeping the original bundle ID is required, but not enough for PN working. You have to use a distribution certificate & an explicit profile with the correct PN entitlement. AltStore/Sideloadly cannot do it so you have to do it manually. I recommend you take a look at SignTools if you need working PN: https://github.com/SignTools/SignTools

This is quite easy to do if you are using SignTools. When signing an app, make sure to select Use custom when choosing bundle identifier options and specify it in the aforementioned format. When it's signed, your sign in should work.

Slightly related, but I've also been working on and off for a few years on my own Type 1 Diabetes management solution (https://github.com/algao1/iv3).

I haven't had time to work on it recently, but it uses ntfy (https://ntfy.sh/) to send alerts and such.

I was thinking of eventually incorporating some kind of automatic remedial solution eventually to help keep my glucose in range, but haven't had any time to look into it yet.

If you go to the settings, there should be a notification category, which then contains another menu "App Notifications" where you can see all the apps that are allowed to receive notifications, but I don't know if this will stop google play services to receive these identifiers.

I use GrapheneOS, so I don't have any google play services running, but for the apps where I need notifications I use https://unifiedpush.org/ (only a few apps implement it) and I host my own https://ntfy.sh server.

Kind of similar, in the early days of COVID, I accidentally discovered that my state's website would have test results available several hours before they sent out the "view your results" email. So I made a script that would check the site every five or ten minutes and then ping me as soon as the result changed to something besides PENDING.

In the course of that I stumbled on https://ntfy.sh/ which solved the notification problem without needing Twitter, and I've used it since then to let me know when long-running scripts complete.

I connect any app that supports https://unifiedpush.org/ to a self hosted https://ntfy.sh instance for fully self hosted push notifications

changedetection.io just donated to the awesome crew over at ntfy.sh

For further monitoring & alerting about critical cpu temperatures (unlikely now) for example, I plan to use notify & something else. Haven't thought about this much yet though.

I've started tossing https://ntfy.sh/ alerts into my Deno apps to get push notifications for things I'm interested in

ntfy.sh

If it was for fun and to learn how, that's fair. But are you aware of https://ntfy.sh?
