Can multiple people use the same temmet to track simultaneous bookings?

Not directly. temmet runs one active session at a time per browser, but you can use separate tabs (each with its own active session) or separate devices.

How do I track the customer behind a booking?

Use the session label for the customer name. The role field is the room type. CSV export carries both columns.

What if a booking exceeds the planned duration?

temmet doesn't enforce a max — the meter just keeps running. Add a phone-stand timer separately if you need a hard cap.

coworking and rooms

temmet is a free browser-based hourly meter — no accounts, no data sent anywhere. If you rent space by the hour, its templates and session history map directly onto your inventory.

for who

Coworking space operators, studio rentals, salon-chair owners, anyone who charges by the hour for use of a physical space.

the job

Track each booking against a room and a rate, end with a clean record of who used what, when, for how long, at what total cost.

how to map it

One template per room or room-type. "Hot desk @ £10/hr", "Phone booth @ £8/hr", "Studio A @ £40/hr". The participant field holds one row — the room — at its hourly rate. The role is the room name; the rate is the price.
Start each booking by loading the matching template. One tap.
Set the session label to the customer. "Acme Co · Tuesday morning meeting" or just the customer's name.
Start the meter when they arrive. End it when they leave (esc).
At end-of-day or end-of-month, export CSV. Each row is one booking with the room, the customer (label), the duration, and the total fee.

the remix

Multi-room bookings as multi-participant sessions. If a customer rents two rooms simultaneously (e.g. studio + green room), add both as participants in Advanced mode. The total updates as the sum.
Use the role field as the SKU. "STUDIO-A · 2024-Q4" if your accounting tool wants codes. CSV export carries the role intact.
Different pricing tiers as different templates. "Studio A · weekday off-peak" at one rate, "Studio A · weekend prime" at another. The template name describes the tier.
Discounts as a manual rate adjustment. If a regular gets 10% off, edit the participant rate after loading the template. The session captures the actual rate charged.

tips

For staff-time tracking on top of room time (e.g. assistant photographer at £20/hr alongside the studio at £40/hr), add both as separate participants. The total is the customer's total bill.
The PDF report is suitable for handing to a customer at the end of a session as a receipt.
If you accept cash payments, the CSV export becomes your daily reconciliation against the till.
Back up your data via JSON export weekly — your bookings are your books.
