About

Caretta Friends

Features
Read full description

Caretta Friends is a field app for volunteers who protect loggerhead sea-turtle (Caretta caretta) nests — from the crawl found at dawn to the night the hatchlings reach the sea. Built for Caretta Gazipaşa on Türkiye's protected nesting beaches, and made to work for any sea-turtle volunteer community. WHAT IT DOES • Shared map of every nest, beach and trash spot — mark a nest in seconds with an auto-geotagged photo • AR nest finder — point your phone and see nests pinned where they physically are • Nest lifecycle — countdown to hatch, a timeline of updates, and an honest temperature-based sex-prediction range • Excavation record — hatching and emergence success, exported as a PDF for the local authority • Field guides and facts — what to do when you find a nest, no lights at night, beach rules • Patrols and coverage — so volunteers don't re-walk a stretch someone already covered • Your impact — how many hatchlings you helped reach the sea, a streak, badges Offline-first: capture works with no signal and syncs when you are back online. Works without an account. Interface in English, Türkçe and Русский. Open source (MIT): github.com/fortunto2/caretta-friends Website: carettafriends.com

Verdict

The call

CoreApp's advantage is device support (3 vs 1) and iOS requirement (13.4 vs 16.0). On price and in-app purchases there is nothing between them.
