You found someone, you agreed to study together every day, and by day two they were gone. It isn't bad luck and it's rarely malice: the arrangement was fragile from the start.
None of these reasons says anything about you or the other person. It says something about the arrangement: if it only holds while you both feel like messaging, it doesn't hold.
Here you don't make a deal with anyone: you book a 25 or 50 minute slot. Whoever booked the same quarter hour is the person you study with, on a video call, each on your own work. You don't have to message first, negotiate anything or swap contacts.
And if the other person doesn't show up? The session starts anyway: for the first 5 minutes we look for someone while you work. If nobody arrives, you choose: carry on with a virtual companion, and if you stay until the end the session counts in full, look for a person in the next quarter hour, or leave. The same happens if the person you were paired with doesn't come into the room within the first minute: the app notices on its own and looks for someone else straight away, without you having to do or report anything. The time stays yours, even when the person changes.
Cams on, mic off if you like: the camera stays on for the whole session, and the microphone can stay muted from start to finish. You each say in one sentence what you're going to do, then you work in silence. If that's exactly what you want, there's a page on sessions with your microphone muted.
Whether you call it a study buddy online or a consistent study partner, most people want one specific thing: someone who actually shows up, every day at the same time. Here, the part that doesn't depend on anyone is the time: you come back to the same slot every day, and at that time a session starts with whoever booked that quarter hour.
I won't promise it'll always be the same person, or that someone will be there in the very first minute. I'll promise something smaller that you can check: at the time you picked, the session starts, and if the other person doesn't arrive, we look for someone else for five minutes.
If you need someone waiting for you to work, not just to study, there's the page on finding an accountability partner; if you want to see what an online study room looks like, here it is.
Usually because the arrangement has no fixed time and depends on one person: it has to be renegotiated every day, and disappearing costs nothing. It says nothing about whoever disappears: it says the arrangement was fragile.
The session starts anyway: for the first 5 minutes we look for someone while you work. If nobody arrives, you choose: carry on with a virtual companion, and if you stay until the end the session counts in full, look for a person in the next quarter hour, or leave. The same happens if the person you were paired with doesn't come into the room within the first minute: the app notices on its own and looks for someone else straight away, without you having to do or report anything.
One sentence at the start about what you're going to do is enough. After that you each study on your own: you can keep the microphone muted for the whole session, and the camera stays on.
