マンホーラー

Manholer is a photo-and-collect app for collecting local manhole designs from all 47 prefectures of Japan.

■ Shoot and Record: Register manhole designs found during walks or travels using your camera or gallery. The app automatically records the shooting location, and you can save them by selecting the prefecture and design type (14 types).

■ Collect and Enjoy the Encyclopedia: View your photographed manholes in a stamp-book-style grid. Enjoy rankings, statistics, and sharing your collection with a "show off your collection" card.

■ Nationwide Conquest Map: Display shooting locations as pins on the map. Aim for completion with a progress bar showing your nationwide conquest rate (◯/47), regional maps, a design encyclopedia, and badges (15 types).

■ Manhole Card Notebook: Record official manhole cards from across Japan. You can check which cards you've obtained, organize them by prefecture, and link them to your photo records.
