## What is Piko?

Piko is a nature observation app for identifying flowers, birds, insects, plants, and animals from photos, then saving each find with the place you saw it.

It does more than suggest a name. Piko shows why a candidate may fit, how confident the result is, and what to look at next when the answer is unclear.

Choose a photo to see animal and plant candidates with visual clues, uncertainty notes, and comparison points. When a species is hard to confirm from one photo, Piko avoids overclaiming and helps you compare similar candidates.

Save what you found as an observation log. Add location when you want, then revisit your finds in a list, calendar, and map. Location saving can be turned off, approximate, or precise.

Piko helps everyday walks, park visits, and trips become your own nature field guide.

Note: Identifications are estimates and are not guaranteed to be accurate.
