This app automatically adds the 'Days Since Birth' to photos of your baby and saves them to an album. It can save pictures of multiple children, so it's fine if you have siblings; up to four children can be added. By entering the date of birth, the app aims to make you feel just a bit more love every time you take a photo. The motivation behind creating this app is the birth of a baby. After the birth, my wife and baby went back to her parents' home to rest. The only time I can see them is during the brief moments I stop by after work. One thing I could do was become a 'camera monk.' I would help a little with unfamiliar tasks like diapers or baths and take daily photos, then go home alone and look at them on my iPhone. Cute... but, wait, I had no idea when each photo was taken. So, I thought it would be nice to show the photos to my child someday, with the date and days since birth displayed. If there are any fathers out there who have become camera monks and are interested, I would be happy to have you use it. 【Caution】 When adding 'Days Since Birth' to images in the photo album, it calculates the days based on the date data held by the 'image' itself. Please be careful, as the date will change if the photo is received from someone else, copied, or if it looks old (for example, if a mother emails a photo of her child, the days are calculated based on the date the email was received). This feature is intended to be used for adding dates to old images taken on your own iPhone.
