The End of Outdated Contact Lists
Every group has the same problem. Someone new joins the medical group, the hospital welcomes a new CMO, or a nurse joins the ICU team, and now that person needs everyone else's contact information and needs to share their own. What follows is a frustrating cycle of group texts asking for phone numbers, shared spreadsheets that nobody updates, and printed directories that are outdated before the ink dries.
GroupBook is our answer to that universal challenge. Built by the team at Med Staff Tracker, GroupBook is a simple yet powerful mobile app that lets any group create, share, and manage a phone directory together. No spreadsheets. No guesswork. Just one shared contact list that every member sees the same way, updated whenever someone in the group makes a change.
Whether you're managing a hospital department, coordinating a family reunion, or running a local book club, GroupBook gives your group a single, reliable source of truth for everyone's contact information.
What Is GroupBook?
GroupBook is a mobile-first shared phone directory app available on iOS and Android. It replaces outdated methods of sharing contact information - group texts, shared spreadsheets, PDF rosters, printed directories - with a living, breathing digital directory that everyone in your group can access from their phone.
The concept is straightforward: create a group, invite your members, and everyone has access to the same contact directory. When a new member joins, their info is added automatically. When anyone in the group adds a contact, it's shared with everyone else. When someone's phone number changes, the whole group sees the update on their next refresh.
How It Works: Four Simple Steps
GroupBook was designed to get your group up and running quickly. Here's how it works:
1. Create a Group
Open the app, tap "Create Group," and give it a name and description. That's it - your group directory is live. Whether it's "ER Night Shift Team," "Johnson Family," or "Downtown Running Club," your group is ready for members.
2. Share an Invite Link
GroupBook generates a unique invite link for your group. Share it via text message, email, WhatsApp, Slack, or any other messaging app your group prefers. There's no need for members to search for your group or navigate a complex sign-up process. Tap the invite link, create your account if you don't have one yet, and you're in.
3. Contacts Appear and Stay in Sync
When a member joins your group, their contact information is automatically added to the shared directory. But it goes further: members and admins can add contacts to the group directory, and those contacts are shared with everyone else. Need to add the on-call line, a vendor, or a colleague who isn't on the app yet? Just add them, and the whole group has the info. No duplicate data entry, no asking "What's their number again?"
4. Call, Text, or Email from the Directory
Need to call the team lead? Text a fellow parent? Email the club treasurer? Open GroupBook, find the person, and tap to call, text, or email directly from the directory. It works the way your phone's built-in contacts do - but for your entire group.
GroupBook Features
GroupBook includes features that keep group directory management simple:
📖 One Shared Directory
Everyone works from the same directory. When a member updates their info or someone adds a contact, the change shows up for the whole group on their next refresh.
⚡ Auto-Created & Shared Contacts
Members who join are added to the directory automatically. Members and admins can also add contacts manually, and those contacts are shared with everyone in the group.
🔗 Link Invitations
Share a link via text, email, or any messaging app. New members tap the link, create an account if they don't have one yet, and they're in. No app codes to hunt down.
📞 Tap to Connect
Tap a name in the directory to call, text, or email that person. The numbers live in the group directory, so you don't have to dig through your own contacts to find them.
🛡️ Role-Based Access Control
Assign Owners, Admins, Members, and Viewers with different permission levels. Control who can add contacts, manage members, and administer the group. Admin roles, member removal and ownership transfer unlock on paid plans.
👥 Multiple Groups
Create or join as many groups as you need, each with its own directory and its own plan - one for your work team, one for your family, one for your soccer league.
🔒 Privacy First
The directory is visible only to members of the group, and data is encrypted in transit.
📱 Native Mobile Experience
Available on both iOS and Android with smooth animations, intuitive navigation, and familiar mobile patterns that feel natural.
Premium Features
GroupBook also offers premium capabilities for groups that need more:
- 📸 Contact Photos: Add profile photos so everyone can identify people at a glance. Snap a picture or choose from your library.
- 📶 Offline Access: Download your contacts locally so you can view your directory even without an internet connection - perfect for events, remote locations, or travel.
- ⭐ Priority Support: Dedicated assistance for your group when you need a hand.
Who Is GroupBook For?
GroupBook was built to serve any group that needs a shared contact list. While our roots are in healthcare, the app is versatile enough for virtually any organization or community:
🏥 Medical Groups & Hospitals
Healthcare teams need quick access to colleague contact information. Whether it's a hospital department, a private practice, or a multi-site medical group, GroupBook gives every team member - physicians, nurses, administrators, support staff - one directory to look up the person they need. That matters during on-call situations, shift handoffs, and emergencies when every second counts.
👨👩👧👦 Families
Extended families spread across cities and states often struggle to keep everyone's contact information current. GroupBook gives your family one living directory that everyone can access - perfect for reunion planning, holiday coordination, and emergencies. When your nephew gets a new phone number, it updates for the whole family.
⚽ Sports Teams & Leagues
Coaches, parents, and players all need to stay connected. GroupBook gives every team a single directory with everyone's contact information, so there is less need for group texts asking for a parent's phone number when a player has to be reached about a schedule change.
🎓 Schools & PTAs
Parent-teacher associations, classroom parent groups, and school activity committees all benefit from having a shared directory. GroupBook makes it simple for school communities to stay connected without relying on the school office as an intermediary.
💼 Small Businesses & Work Teams
Small businesses and department teams need a quick, easy way to look up coworker contact information. GroupBook gives them a simple shared company directory without a lengthy setup.
🎭 Clubs & Social Organizations
Book clubs, running groups, hobbyist communities, HOAs, music groups, volunteer organizations - GroupBook gives any club or social group one shared directory so members can reach each other.

Why Med Staff Tracker Built GroupBook
At Med Staff Tracker, our mission is to solve workforce management challenges in healthcare and beyond. We build tools that help medical organizations manage scheduling, onboarding, credentials, and staffing operations.
That work convinced us of something simple: keeping a shared contact list current is hard for any team, not just healthcare teams. Think about how often a physician needs to reach a colleague during an emergency, a nurse needs the on-call number for the covering physician, or an administrator needs to coordinate across departments.
We built GroupBook to solve exactly that - a focused app with one job: it gives any group a shared phone directory that members keep current.
Getting Started with GroupBook
Getting your group on GroupBook takes only a few steps:
- Download the app from the App Store or Google Play.
- Create your account with your name, phone number and email, then confirm the verification code we send you.
- Create your first group and give it a name.
- Share the invite link with your group members.
- Start connecting - your shared directory is live!
