# Electrical Calculations vs SKM Mobile

Electrical Calculations also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs every 7 months). SKM Mobile's advantage is ads (none vs shown) and iOS requirement (12.2 vs 15.0). On price, in-app purchases and device support there is nothing between them.
