My Singing Monsters The Lost Landscape [NEW]
Your primary tool was the "Echo Locator," a tuning fork-like device. Monsters were physically invisible until you found their "frequency." You had to walk around specific landmarks (a glowing rock, a hollow log) and listen. The game used the iPad’s gyroscope; moving the physical tablet would cause the stereo audio to shift, helping you triangulate where the monster was hiding.
By 2017, the servers for verifying the download were shut down. If you deleted the app from an old iPad, it was gone forever. my singing monsters the lost landscape
