iGroup makes grouping for gatherings, classes, events, and teams faster, clearer, and fairer. From inviting participants to sharing results, it is all easy from your phone. Invite Codes & QR Codes: Easy to Join After creating a group, simply share a 10-character invite code or QR Code. Participants can join from their phones. Once everyone has arrived, draw groups right away and spend less time taking attendance, making lists, and double-checking details. Three Modes for Every Occasion • Invite Code mode: Great for gatherings, classes, and larger events where everyone joins from their own phone. • Manual mode: Create a participant list directly when one organizer is handling the setup. • Quick mode: Set the participant count and grouping preferences to get results fast—no names required. Group Your Way Set a maximum group size or choose a more balanced option that avoids one-person groups. When needed, enable gender balance to better suit your activity. Clear Results at a Glance When grouping is complete, clear group cards show members and assignments at a glance—perfect for announcing results or sharing them with everyone. Local Modes for Peace of Mind Manual and Quick modes stay entirely on your device. They do not create a cloud room or upload participant data. Leave paper slips and messy lists behind. With iGroup, save your time for what matters most.
