Portable Inventory helps you to keep track of the count of anything you want. Personal stuff, office supplies, product storage, etc. You can add different items into the app, set its initial count, warning count, and separate items by groups. Each item will be displayed as different colors on the main page, so that you can add or reduce the count. When an item’s count is equal or less than the warning count, a little yellow triangle with an excalmatory mark will be display on the item, and the group it belongs to. In addition, the app provided various functions to see statistics for your items or groups. You can check out the increasing, or decreasing ranking list of your items or groups in a specified time period. You can also see the change logs for all items and groups. The app works both on iPhone and iPad, and fully supports iCloud. You may edit your items across all your devices and your data will be safely stored in iCloud.
