Verdict
The clearest difference is in-app purchases: Regla de tres at none against interplex's 1. Regla de tres also leads on device support (3 vs 1). interplex's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 19 months). On price and iOS requirement there is nothing between them.
