Use vibration close to your body, keep the sound modest, and move the task out of the room. Test it while your roommate is awake, because 6 AM is a terrible time to discover that your setup shakes the whole desk.
Your alarm is happening to both of you
You may need to be up at 6:30 while your roommate got home from work at 2. Neither schedule is wrong, and neither person should have to quietly resent the other for a semester. Talk about the alarm before it becomes a recurring argument.
Try the actual sound and vibration together during the day. Put the phone or watch where it wakes you without rattling a hollow table. Agree on what happens if you don't respond. A roommate saying your name once is generous; becoming your daily backup alarm is a different job.
Get the noisy part out of the room
Start with a wearable vibration if you reliably notice it, backed by a low sound near your side of the room. Then finish the mission in the bathroom or hallway. A barcode on your toothbrush works well because it gets both you and the alarm away from the bed quickly.
Keep clothes and toiletries ready so you aren't opening drawers, turning on the ceiling light, and searching for socks. If quiet cues consistently fail, be honest about that too. You may need a different room arrangement, schedule conversation, or accommodation rather than an escalating alarm war.
Common questions
Is vibration enough for a heavy sleeper?
It is for some people and not for others. Test it on a low-stakes morning and keep a sensible backup until you know.
Should my roommate wake me if I miss it?
Only if they agree. Ask for occasional emergency help, not an open-ended responsibility they never signed up for.
