commin vs 家信

commin is a communication app built for communities. commin isn't just an ordinary group chat. It connects one administrator with each member in a star-shaped network: the admin (a teacher, a building/condo manager, a club or association officer) can reliably reach every member, while members never see each other's phone numbers, contact details or personal info—and don't see each other's messages. So everyone's privacy is protected (between parents, between residents) while you create a safe place to stay in touch—a teacher with each class's parents, a condo or building manager (HOA) with each unit's residents, PTA or neighborhood-association officers with their members and households. Whether it's a club, a team, the PTA, a hobby group, your neighborhood, your condo or homeowners' (HOA) association and its board, or your family—commin brings together announcements, chat, photos, plans, and calls for every community you belong to, all in one place. DIFFERENT FROM AN ORDINARY GROUP CHAT 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, so nothing slips through the cracks. 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, club activities) - A condo or building manager / HOA & each unit's residents - PTA or neighborhood/residents' association officers & their members and households Key Features MAIL (announcements) Post and share announcements with your whole community, the way you'd send an email. Important messages reach every member and won't get buried or scroll away. TALK (group chat) Chat with members in real time. Sharing photos and files is quick and easy. Voice & Video Calls Start a voice or video call right inside the app. Stay face to face, no matter the distance. ALBUM (shared photos) Share and save photos from events and everyday moments with everyone in your community. Keep all your memories together. CALENDAR (shared schedule) Share plans and events with members. Check the schedule and see who's coming at a glance. MEMBER (member management) Manage your community's members. Sending invites and approving requests is simple. Perfect For - Staying in touch without members having to share each other's contact details - Having an admin reliably reach everyone with the messages that matter - Keeping a group's messages and information all in one place - Condo and homeowners' (HOA) associations and boards: general and board meeting notices, attendance checks, and circulars - Groups where chat alone lets important messages slip away - Organizing photos, plans, and announcements by community With commin, your community feels closer—and runs more smoothly, with everyone's privacy protected.
