Chirastock is a household inventory app you can share with family and housemates. No counting required. Tap blue, yellow, or red to keep a rough view of what you have at home. Check the app instead of asking, "Do we still have that?" or "Did someone already buy it?" - Track stock with three colors Blue: have it Yellow: time to buy soon Red: out You can decide what each color means for your household. For items where it helps, set a rough amount for each color (in steps of 0.1). - Share with your household in real time Create a group and send the invite code to your family. Everyone sees the same list. When someone changes a color, it updates on every member's screen right away. This helps reduce duplicate buys and "maybe someone got it" guesses. - See who changed what, and when Every status change is saved to the history automatically, so you can check who updated an item and when. - Easy to find, easy to use Pin: keep the items you check most at the top (shared with the group) Search: type part of a name to filter items Sort: arrange your list the way you like Photos and notes: tell similar items apart Store links: save a product URL and open it in one tap when you restock - Separate groups by place Kitchen, bathroom, living room, and more (multiple groups need Premium).

I wanted something more personal than a calendar and more beautiful than a simple tracking app, so I built the app I wanted to use with my own partner. Thank you for using Itonamy. We hope it becomes a special place for your memories together. --- Terms of Use: https://mcg-dev.jp/apps/itonamy/terms/en Privacy Policy: https://mcg-dev.jp/apps/itonamy/privacy/en
