All the vibrating alarm clocks I could find do not sync with your phone, and have to be set manually. I thought about getting an Arduino, but then I will have to build the whole thing by myself. The only logical conclusion I could come up with is to get a programable vibrator. But most of them are either very expensive of look too much like a vibrator (sus).

What you are looking for is a “Bed shaker”. These are often used by the deaf to wake up. A relatively cheap phone-connected one can be found here but it’s iphone only. This one works with Android. Both use proprietary apps. The website linked was just at the top of a Google search, you can find stuff like this on Amazon as well.
Isn’t a phone technically a vibrating alarm clock?
A phone won’t vibrate strongly enough for you? You could adjust the intensity of those you know
How about a smart watch? I realise this is kind of specific but I have a Pixel 8 phone and a Pixel Watch 2. The alarms sync, and the vibration on my watch is enough to wake me up.
This is my recommendation as well. Having the alarms sync is one of my favorite things with the watch. And when you stop it on one it stops it on both.
I blindly reach down to my watch and press the button there to snooze the alarm, it’s great!
Might be kind of difficult to get to sleep with that inside you…
Unless that’s what you’re into I guess…

falling asleep is fine, getting good sleep is hard, waking up with a toy inside your now dry hole is rough
