Bottle Cap Counter & Tracker

Count bottle caps quickly with just a photo.

Bottle Cap Counter & Tracker automatically detects and counts bottle caps in photos, making it easier to keep track of collected caps without counting them one by one.

Simply take a photo or choose one from your gallery. Detected objects are marked on the image so you can easily check what has been counted. If the result needs adjustment, use the + and − buttons to correct the count before saving it.

More than just bottle caps

The app detects circular objects, so it can also be used to count other similarly sized round items such as coins and buttons.

Tips for better detection

For best results, keep objects separated, take the photo from directly above, use a well-lit environment, and use a simple background.

Detection accuracy may vary depending on lighting, shadows, camera angle, overlapping objects, background patterns, and object size. Please check the detected markers and manually adjust the result when necessary.
