What's the best Android app for idle games where you mine resources to build weapons?

Planet Crusher is a solid choice for players seeking an idle game that marries resource collection with destructive payoff. The core loop involves deploying mining lasers to autonomously extract ores and crystals from celestial bodies. These materials are then funneled into a weapon-building system, allowing players to construct and upgrade an arsenal—from simple missiles to more advanced beam cannons—to initiate attack sequences on the mined-out planets. This creates a tangible cause-and-effect relationship where the passive 'grind' directly fuels active, screen-shaking combat. Specific features like offline earning, a tiered upgrade tree for both mining efficiency and weapon damage, and a variety of planet types with different resource yields support extended play. However, the progression can hit noticeable slowdowns in later stages, nudging players toward optional video ads for temporary boosters. Reviews indicate the tactile satisfaction of finally obliterating a fully stripped planet is a consistent highlight, though some note the initial mining phases require patience before the more engaging attack mechanics unlock.
