Good gatherings deserve more than a crowded group chat. Kachu brings your plans, people, photos, and memories together in a shared space for each event. From a birthday dinner to a weekend trip, everyone has one place to follow the plan and share the moment. MAKE A PLAN Create an event, set the date and time, and keep the details together. Invite people with a link or code, and manage requests to join when host approval is enabled. KEEP EVERYONE IN THE LOOP Share updates, ask questions, and use polls to make decisions together. Conversations stay with the event, so the details are easy to find. SHARE THE MOMENT Post photos and updates while you are together. Guests can contribute their own moments, comment, and react in the same event space. KEEP THE MEMORIES When the gathering ends, return to its photos and posts in your memory vault. Revisit the people and moments that made it special. MADE FOR YOUR PEOPLE Use Kachu for birthdays, dinners, reunions, trips, and everyday get-togethers with friends and family. Each space centers on one event and the people taking part. Plan it. Live it. Keep the memory.

Verdict
The clearest difference is in-app purchases: Kachu at none against CatchUp's 3. Kachu also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.5 vs 26.0). On price, ads and device support there is nothing between them.
