Find a free room. See how long it stays free.
Every teaching room at THD Deggendorf, straight from the official timetable, sorted by how long it stays free. Then study there, alone or with friends, or in the same rhythm at home.
Why use it
Stop trying doors
On a normal weekday, around a hundred teaching rooms stand empty for hours. The app shows you which ones, and for how long, before you walk over.
Know before you walk
Free for 10 hours, or until the 14:00 lecture. The rooms that stay free longest come first.
Plan ahead
Tomorrow at 9 or any time this week. Before the doors open, see what will be free.
Just open it
No account, no ads, nothing to install. Free and open source.
How it works
From the corridor to a desk in three steps
No more walking the corridors trying doors. The app knows every room's timetable and tells you how long it stays free.
Find a room
Free rooms, sorted by how long they stay free. On the map or as a list, for now or for later today.
Start focus
One tap starts Pomodoro, 25 minutes of focus and 5 of break. It stays on your phone and ends before the next lecture.
Watch your semester grow
Every block darkens your focus graph, kept on this device. No account needed.
See where your batch is
Rooms show who from your batch is studying there, like "AIN 7 · 1 studying". Walk over and join them.
Focus with your batch
Public shows your batch where you are; Private only shows the room as taken. Study together invites friends with one link.
Your semester, everywhere
Your focus graph, saved rooms and study tables, the same on your phone and your laptop.
A study profile is free: an email code, your programme and your batch.

Focus sessions
A rhythm that fits your day
Focus blocks and breaks, like Forest or a Pomodoro timer, right where you study.

Keeps going on a locked phone
In the Android app, a lock-screen notification counts down and tells you when the break is over.
-
Breaks never count
After each break you tap Start block. If you don't, the session ends at the last block you actually did.
-
Ends before the next lecture
Blocks are planned around the room's timetable, so you never end up in the middle of a lecture.
Focus at home
No room? Focus at home
The same rhythm of blocks and breaks, just without a room. The Focus tab starts it in one tap and holds whatever is running, at home or on campus.
-
Breaks you can hear
Coffee pours when a break starts, and three bright dings call you back. Pick Coffee break, Jingle or Chimes, for home and for campus, or keep your phone's own sound.
-
Stays on your phone
Nobody sees a session at home. Signed in, only the finished minutes count in your focus graph.
-
Weekends count
A weekend or holiday with focus now adds to your streak. Rest days without focus only pause it.
Study together
One link for the group chat
Pick a time the room is free, choose the seats and send the link. Friends take a seat with an email code, no app needed.
-
Start in step
At the time, everyone starts focus in the same rhythm, so breaks line up. Already focusing? Invite people into the session you're running.
-
Private, or with your batch
Private, others only see that the room is taken, never by whom. Public, your batch sees where you are and can join.
-
Never a booking
The app doesn't reserve rooms. If a lecture shows up, the study table warns you and suggests a free room.
Student groups
Your group, your page, your gatherings
Clubs and initiatives get their own page and invite people to game nights, talks and big study sessions. This is how a group gets in:
- 1
Register in the app
Profile → Register your group, with the group's public details: name, short name, website.
- 2
Checked in the open
One proof in the public registry, checked by a THD AI member who isn't you. The tag can't be bought.
- 3
Host gatherings
In rooms THD approved for you. People reply Going, Maybe or Can't; you see how many to plan for, never email addresses.
Privacy
Your focus time is yours
No account needed
Finding rooms and focus sessions work without signing in. You only need a study profile for your batch. The web app counts page visits without cookies; invite links are never recorded.
Your graph, on your devices
Without an account, your focus history never leaves your phone. Signed in, only dates and minutes sync between your devices; rooms stay on the device.
Straight from THabella
Rooms and timetables come from THD's public scheduling system. If it's ever down, rooms stay listed and focus still starts.

Good questions
Is this an official THD app?
No. It's a student project. It uses the public room and timetable data from THabella, but the university doesn't run it.
How accurate is "free"?
As accurate as the timetable: a room counts as free when nothing is booked in it right now. Some rooms are still locked; the app marks those "may be locked".
Can I book a room?
No. The app shows free rooms and lets you invite people, but it never reserves a room. Official bookings go through THD.
Do I need an account?
No. Without one, everything runs on your device. An email code is enough to take a seat at a study table; you only need a study profile to claim rooms and study with your batch.
Can others see where I study?
Only if you want them to. Without a study profile nobody sees anything. With one, a private session only shows "taken"; a public one shows your batch the room, and your name only if you turn it on.
Can I use it on my phone and laptop?
Yes. Signed in, your focus graph is the same on both, and a session running on your phone shows on your laptop too, where you can start the next block or end it.
Does it work offline?
Yes. Rooms and the day's timetable are cached, and a focus session keeps running without a connection. If THD's timetable itself is down, the app lists rooms as "availability unknown" instead of guessing.
