Read full descriptionHide full description
In 2019, a cleanup of Henderson Island was led by Howell Conservation Fund. The team successfully cleared 100% of the beach, overcoming countless challenges. Due to a number of global and local issues, the 6 tonnes of collected materials are awaiting retrieval. Henderson Expedition 2024 builds on Mission 2019 to finish what was started by Howell Conservation Fund, now in collaboration with Plastic Odyssey. The expedition’s mission is to build an international coalition to complete the cleanup of the world’s most polluted beach and close the loop on this plastic pollution, making the Impossible Possible.

Verdict
The clearest difference is in-app purchases: Impossible Cleanup at none against ReadBack's 7. Impossible Cleanup also leads on iOS requirement (15.0 vs 18.0). ReadBack's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
