About this app

The Teacher's Satchel is the free, offline tool designed to simplify your daily life as a teacher.

No account needed. No internet required. No ads. Just a simple tool that does what you need, right from your phone.

━━━ MANAGE YOUR CLASSES ━━━

- Create as many classes as you need
- Add students manually, one by one
- Or import your lists from an Excel file (.xlsx), CSV, TSV or TXT
- Smart import wizard detects your columns and shows a preview before importing
- Tap a student to open their profile and manage their relationships with classmates
- Archive classes at the end of the year to keep a clean history

━━━ RANDOM DRAW ━━━

Need to pick a student at random? A volunteer for the board?

- Draw a student in one tap
- The app keeps track: every student gets picked before anyone is drawn again
- Already-drawn students are visually crossed out
- Reset the cycle whenever you want
- You can also manually mark a student as drawn or not

━━━ RANDOM GROUPS ━━━

No more wasting 10 minutes forming groups by hand.

- Choose group size (2, 3, 4, or 5 students)
- Uncheck absent students
- Shuffle with one tap
- Smart groups: favor students who get along, separate those who don't
- The app avoids repeating the same pairs across saved generations
- A red conflict indicator warns you when incompatible students end up together
- Not satisfied? Re-shuffle as many times as you want
- Save your groups with a name (e.g., "Science Project")
- Find them later with full version history
- Export as CSV or text, or share directly

━━━ ASSESSMENT TIMER ━━━

A simple, configurable timer for exams and assessments.

- Set a base duration with a visual dial
- Enable extended time (tiers temps) for students with accommodations
- Add intermediate alerts (half-time, 15 min, 5 min remaining)
- Choose end signal: vibration, sound, or both
- Timer keeps running in the background with notifications
- Project the timer on the classroom screen via web display

━━━ WEB DISPLAY ━━━

Project your groups on the classroom screen — no cable, no USB stick.

- Open the web display on any computer or projector with a browser
- Scan the QR code or enter the session code from your phone
- Your classrooms and saved groups appear instantly on screen
- Browse and display any group generation in a clear, projector-friendly layout
- All data is sent directly from your phone — nothing is stored on a server
- The connection stays alive even if you switch apps

━━━ STUDENT RELATIONSHIPS ━━━

You know which students work well together and which ones don't. Put that knowledge to use.

- From a student's profile, add positive and negative relationships
- Incompatibilities are automatically bidirectional
- When shuffling, activate smart options to take relationships into account
- A conflict indicator warns you if two incompatible students end up in the same group

- Free — no in-app purchases, no subscription
- Offline — works without internet, even in a room with no wifi
- Privacy-first — no data ever leaves your device
- Fast — designed to be used standing up, between classes

What’s new

✨ New: build the seating plan for each classroom and assign your students directly in the app.
🖨️ Seating plan: export it as a printable PDF, ready to tape on the desk.
✋ Seating plan: drag a student without a long-press. The card stays visible above your finger, the target seat is highlighted, changes animate briefly, and a gentle vibration confirms you've picked them up.
