Have you ever wondered, "How many days have passed since I started dating that person?" You probably didn't ask the other person, did you? That may have been the reason for the fight. Think back to "that day" that you are interested in. Was it the day you met someone important? The day you went on your first trip abroad? The day you finished reading a book that shocked you so much that it changed your outlook on life? The day you made a big mistake that changed you. Or... When is "that day" that is important to you? How much time has passed since that day... until this moment now? "ANOHIKARA" is an app that allows you to check how much time has passed since such an important "that day" for you, with simple operation and a sophisticated and beautiful design. * Regarding data management for "ANOHIKARA" (Please read this before using) In order to protect personal information, this app has a policy of not acquiring any personal data from customers (we do not know any information about the customer themselves or the contents of the customer's registration). As a result, when a problem occurs with your data due to various factors such as OS upgrades, model changes, your device or settings, or installed apps, you will not be able to view your data, so it may be difficult to identify the cause and reliably recover your data. Therefore, we ask that you use this app only as an app to calculate the elapsed time from a certain date (not an app intended for data storage), and that you manage the original data yourself in a secure manner.
