About this app
commin is a group communication app built for every community you belong to.
commin isn't just another group chat. It connects one administrator with each member in a star-shaped network: the admin (a teacher, a condo/building manager, a club or association officer) can reliably reach every member, while members never see each other's phone numbers, contact details, personal info or messages. So everyone's privacy is protected — between parents, between residents — while you create a safe place to stay in touch.
For your child's school or class, the PTA, a club or sports team, your neighborhood or residents' association, your condo or homeowners' (HOA) association and its board, or simply your family, commin brings the messages, group chat, photos, schedules and calls for each community together in one place — and a single announcement reliably reaches every member, right from your phone.
HOW COMMIN IS DIFFERENT
A star-shaped network, not one big group chat
Instead of everyone mixing in a single group, an administrator (a teacher, manager or officer) connects with each member one-to-one. Important news and one-to-all announcements go from the admin straight to every member.
Privacy protected between members
Parents never see other parents' numbers, and residents never see other residents' details — no phone numbers, contact info or personal data are exposed between members. It solves the everyday "I want to stay in touch, but I don't want to share my number" problem.
Safe communication spaces you can create
- A teacher & each class's parents (school, kindergarten, nursery, lessons, clubs)
- A condo or building manager / HOA & each unit's residents
- PTA or neighborhood/residents' association officers & their members and households
KEY FEATURES
Mail (announcements & broadcasts)
Post important news and one-to-all announcements to your whole community, as easily as sending an email. Nothing gets buried, so every member actually sees what matters — the modern way to run the contact network you used to keep on paper.
Talk (group chat)
Chat with your members in real time, and share photos and files in a couple of taps.
Calls (voice & video)
Start a voice or video call right inside the app. Even when you're far apart, you can talk face to face.
Album (photo sharing)
Collect and save photos from events and everyday moments with everyone in the community, so your memories stay together.
Calendar (shared schedule)
Share plans and events with your members. Everyone can see the schedule and who's attending at a glance.
Member management
Manage who's in your community, and handle invitations and join approvals simply.
PERFECT FOR GROUPS LIKE THESE
- School and class communication, plus PTA and parent group announcements — a teacher reaches each parent while parents' privacy stays protected
- Kindergarten and nursery class updates for busy parents
- Clubs, sports teams and after-school activities sharing notices and schedules
- Neighborhood and residents' association notices, circulars and reminders
- Condo and homeowners' (HOA) associations and boards: general and board meeting notices, attendance checks, circulars and one-to-all messages to residents
- Lessons, hobby circles and volunteer groups staying in touch
- Family, relatives and neighbors sharing quick messages and photos
GREAT IF YOU WANT TO
- Stay in touch without members having to share each other's contact details
- Have an admin reliably reach everyone with the messages that matter
- Move your club, PTA, neighborhood or class contact network off paper and into one app
- Keep every group announcement and update in a single, organized place
- Stop important messages from scrolling away and getting missed in a busy chat
- Organize photos, schedules and communication community by community
Move from scattered messages and old-fashioned phone trees to group communication with commin, and bring every community closer and smoother — with everyone's privacy protected.
