About this app

"Where did I put that photo from that time?" "The travel stories and the kids' school stories are all mixed up and I can't tell what's what..."

Do you have these kinds of problems with communication with your family or partner? memStock is a new communication app that lets you organize and "stock" your daily conversations and photos by topic.

From casual everyday conversations to planning important events and recording your children's growth, neatly organize scattered information and turn it into a "family asset" that you can always look back on.

■ Three Features of memStock

"Talk Rooms" that can be created for each topic: You can create dedicated rooms for each topic, such as "Travel Plans," "School Announcements," "Tonight's Dinner," and "Children's Album." Since conversations don't get mixed up, important plans and discussions proceed smoothly.

"Thread Function" to organize conversations: The app features a thread function that allows you to branch out and deepen conversations from a single topic. Even when you want to discuss a specific topic in detail, it doesn't disrupt the overall flow.

"Shared Album" linked to chats: You can create albums for each chat room. Create albums for each event in your travel room, such as "Hawaii Trip," "Visiting Parents," or "Hokkaido Food Tour." Similarly, create albums for "Birthday Party," "Shichi-Go-San (7-5-3 Festival)," or "Entrance Ceremony" in your parenting room.

■ Useful in these situations:

For Couples/Married Couples

Create a "Next Trip" room to share links to desired destinations and accommodations.

Manage to-do lists and wedding attire photos in the "Wedding Preparations" room.

Record household expenses in the "Household Finances & Payments" room.

For Families with Children

Share growth records with your spouse in the "Children's Photos" room.

Store printed photos and schedules in the "School & Events" room.

Discuss birthdays and Christmas items in the "Wish List" room.

■ Recommended for:

Those who want to cherish conversations and photos with their partner

Those who find it stressful when important information gets lost in chats like LINE

Those who want to manage their children's photos and daily communication in one app

Those who enjoy planning trips and events

■ The meaning behind memStock: Memory + Stock. We want to build up those everyday interactions that might otherwise fade away into irreplaceable memories. This app was born from that idea. We hope memStock can become a place that deepens the bonds with your family and partner.
