Verdict

The call

The clearest difference is in-app purchases: GPSLoggerS at none against RubiMask's 3. GPSLoggerS also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.0). RubiMask's advantage is update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.
