Always outdated
Multiple trip or course screenshots floating in the group — nobody knows which one is current.
LINE is great for chatting, not for sign-ups
Every time someone joins or drops out,
the entire roster needs to be redone.
＋
Easy to miscount
Group sign-ups, added spots, or last-minute cancellations — the organizer has to recount every time.
?
Same questions on repeat
Any spots left? Will it happen? Am I registered? Checking the spreadsheet and replying every day.
Sound familiar?
Your typical Wednesday morning.
The weekend trip was just posted in the group — questions start rolling in one by one.

Everyone signs up themselves — you don't answer a single availability message.
Three steps
Keep using LINE —
keep event data in one place.
No need to change community habits. Just replace the sign-up thread text with a single live link.
1
Create event dates
Set dates, times, location, price, minimum headcount, and max capacity.
2
Share the link to your group
Partner instructors or students pick dates, enter headcount, and fill in the info you need.
3
Availability updates automatically
Forming, confirmed, full, waitlisted — everyone sees the same status.
One product, two common use cases
If you're organizing dive events,
DiveForm works for you.
🚤
Boat operators
Publish sailing dates in bulk. Let partner instructors check availability and reserve spots for multiple students at once.
🤿
Independent dive instructors
Publish courses, pool sessions, depth training, or fun dives. Let students sign up, pay, and check status directly.
No more matching payment screenshots

Participants submit transfer details or payment proof directly. You confirm, reject, or remind — no more digging through LINE for photos and names.
- Each registration has its own payment status
- Confirmed, pending, and unpaid — clearly separated
- Automatic reminders before payment deadline

FAQ
Start with just one event.
Do participants need to pay or download an app?
No. Partner instructors or students just open the link in a browser, pick a date, and sign up.
Can I sign up multiple students at once?
Yes. Group leaders just enter total headcount — each student doesn't need their own account.
Do I still need LINE?
Yes. LINE stays for chatting and sharing. DiveForm handles dates, headcount, and status.
What if minimum headcount isn't reached?
The page shows how many more are needed. When the deadline hits, it can notify or cancel based on your settings.
For your next dive event,
don't start another LINE sign-up thread.
Try it free with a real boat trip, course, or training day — see how many messages you can stop answering.
