GM Shape APP is used to control the steady and continuous output of electrical pulse of smart box.

Verdict
The clearest difference is in-app purchases: GM shape at none against eCalculator's 1. GM shape also leads on ads (none vs shown). eCalculator's advantage is update cadence (every 3 months vs every 12 months). On price, device support and iOS requirement there is nothing between them.
