Great/Fun/Best survival game on IOS/Android?

[Moashu]

After playing on my phone couple of survival games like Survive and Buried Town(Zombie survival but still a survival game lol), i was wondering which survival games on IOS and/or Android is actually fun and requires no in-game purchase for other people?

Not sure if it counts as survival game but I like the game hopeless: the dark cave
Some of the other hopeless games look pretty good but I haven't tried them myself
