Chirastock - Household stock, shared with your family Make household stock simpler and easier to keep up with. Chirastock is an inventory app you can use together with family and housemates. No more wondering, "Didn't we already buy that?" Main features Track stock with three colors • Blue: In stock - you still have plenty • Yellow: Running low - time to buy more soon • Red: Out of stock - you need to buy it now You can see what you have at a glance, without making a shopping list. Live sharing Share stock with family and housemates in real time. When someone updates an item, everyone sees it right away. That helps you avoid buying something another person already bought. Groups Organize stock by place or purpose, such as the kitchen, bathroom, or living room. Creating more than one group is part of the Premium plan. Store links Save a store URL on an item and open the product page in one tap when you run out. Restocking stays quick. Simple to use The design is meant for everyday use, with little effort. Adding an item is straightforward, and you can attach a photo and a note. Item photos A photo makes it obvious which product it is. This helps when you keep similar items. Stock history Every status change is saved automatically. You can see when an item changed, and who changed it. Free plan and Premium plan Check how many items you can save before you download. Free plan • Groups: 1 • Items: up to 20 • Banner ads: shown Premium plan (one-time purchase, no extra fees) • Groups: up to 10 • Items: up to 50 per group (up to 500 in total if you split them by place) • Banner ads: hidden Split items into groups such as Kitchen, Bathroom, and Living Room, and you can register things from around the house without putting them all in one list. The Premium price pays for extras such as higher limits and no banner ads. Running the app has a cost, so there is a limit on how many items you can save. Who it's for • People who want to share household stock with family or housemates • People who want fewer duplicate purchases • People looking for a simple inventory app • People who want shopping to take less effort • People who track stock in more than one place Examples Kitchen Share condiments, canned food, and frozen food with your family. When someone uses the last of an item, everyone else can see it. Everyday goods Track toilet paper, detergent, shampoo, and other daily items. When something runs low, you know what to buy. Office or shop Small offices and shops can share stock as a team and avoid ordering the same thing twice.

Verdict

The call

The clearest difference is in-app purchases: こどもサイズ帳 at none against Chirastock's 1. こどもサイズ帳 also leads on ads (none vs shown). Chirastock's advantage is update cadence (every 3 days vs fortnightly) and device support (3 vs 1). On price there is nothing between them.
