Verdict

The call

The clearest difference is rating: Idle Mastermind at 4.6 against SCP Laboratory Idle Mobile app's 3.9. Idle Mastermind also leads on update cadence (every 6 weeks vs every 7 months) and ratings volume (441 vs 22). SCP Laboratory Idle Mobile app's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.
