失効ウォッチ - 使える資産の期限管理

Shareholder benefits, hometown tax donation thank-you catalogs, gift certificates, and gift vouchers.

This app lets you easily see all your "usable assets"—which vary in type, issuer, and expiration date—all in one place, sorted by their expiration date.

It provides a clear overview of your total usable assets and sends you notifications before they expire.

It's a tool to help you manage your valuable assets yourself and use them to the fullest.

・Have multiple shareholder benefits or hometown tax donation rewards
・Manage many gift certificates and vouchers
・Want to keep track of expiration dates and use each one up

■ Main Features

■ Pricing (One-time purchase)

Basic functions such as total summary, deadline list, notifications, and export are always free.

■ Privacy
Asset issuer, amount, and notes are stored only on your device.
Only anonymous usage data (screenshots, operations, etc.) is sent for app improvement purposes, and this can be turned off in the settings.
