Shared Diary
Read full descriptionHide full description
[Overview] This is a diary app that lets you share your days with people you care about. Here are some ways you can use it: * Jot down your thoughts and feelings as a personal diary * Share your daily life with close friends or your partner * Talk about your day with your child * Use it with your spouse to share little things—like gratitude, happy moments, or updates about the kids * Use it in a small team to keep track of daily work or share reports Once you get into the habit of writing a diary, you start noticing more things around you. It helps you become more aware of the little joys in everyday life, and it also strengthens your ability to express your thoughts in words. Being able to put your feelings and ideas into words boosts your communication skills, which can really help in your relationships—at school, work, or at home. If reading this made you think, "Maybe I’ll give diary writing a try," we’re happy to hear it. Even writing just 20 or 30 characters a day is totally fine. And honestly, you don’t even need to use this app—we just hope it encourages you to start. [Recommended for people who] * Want a simple, easy-to-use diary app * Want to build a daily writing habit * Feel shy about expressing feelings out loud * Want to do a shared/partner diary * Don’t want to exchange LINE but still want a casual way to communicate in text Term of service(EULA): https://originate-aster.co.jp/shared-diary/terms privacy policy: https://originate-aster.co.jp/privacy-policy/

SafeCarta helps you organize the information your family may need during emergencies, hospital stays, caregiving, disasters, or estate procedures. Create a profile for each family member and store medical details, medications, allergies, emergency contacts, insurance policies, important documents, money memos, digital asset notes, and photo or PDF attachments. You can also record where originals are stored so family members know what to look for. Generate an emergency card PDF or a family binder PDF in a few taps. Protect records with Face ID, Touch ID, or passcode, keep data on-device by default, and use reminders, backups, and optional iCloud sync when you need them.
