経過期間ウォッチャー ～それいつ使い始めました？～

We tend to forget how long it has been since certain things, and it is not rare for us to ask ourselves these questions during our daily lives:
“When did I start using this battery? How many times have I charged it?”
“I wonder how long it has been since I changed this bulb…”
“Period Elapsed Watcher” comes in handy in those situations.
With Period Elapsed Watcher, you can easily keep track of the amount of days passed since you started using something, and the number of times that you have used it.
Below are its main functions:
- Management of elapsed time.
- Management of the number of times used.
- Management of additional information.
- Evaluation management of the eligible features (on a scale of five grades)

Tips for use:
It is useful to write an ID on the object to be kept track of, and manage it in association with its registered name.
