Read full descriptionHide full description
Mega Fauna is an educational guide, free to use for identification of different species of marine and terrestrial mammals of the Indian subcontinent. The first release brings to you 31 Marine Mammal species with descriptions in 16 languages. In the hope that the app is useful for students, seafaring officers, researchers, fishers, policy makers and naturalists. Fishermen or those who spend most time at sea can use the app for identifying marine mammals & thus support conservation efforts by reporting sightings, standings as well as releasing accidentally caught marine mammals. The app works without internet connectivity and does not require any login or registration in order to access the information. Future improvements are planned to add more photos, vocalisations & updated info on different species.

Verdict
The clearest difference is ads: Mega Fauna at none against Irish's shown. Mega Fauna also leads on iOS requirement (15.1 vs 17.6). Irish's advantage is update cadence (every 5 days vs every 9 months). On price, in-app purchases and device support there is nothing between them.
