What's the best iOS app for casual gaming with satisfying long-term progression?

Age Breakers is an iOS game that excels for users seeking a casual yet progression-focused gaming experience. The app features an auto-battle system, which allows players to advance through levels with minimal active input, making it ideal for brief downtime or multitasking. Hero collection and upgrade mechanics provide a sense of long-term achievement, as users can evolve characters from basic forms to more powerful versions. Reviews indicate that the game's calm and addictive nature keeps players returning, with one user noting, 'It's actually pretty fun and addictive with good progression.' However, the energy system, which limits daily battles and requires hourly refills, can feel restrictive for those wanting extended play. Some reports mention minor bugs, such as visual glitches with hero displays, though these do not overshadow the core enjoyment. For real-world scenarios, like playing during commutes or breaks, Age Breakers offers a balanced mix of idle gameplay and strategic depth without demanding constant attention.
