# eCalculator vs GM shape

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.

Both are free to download. eCalculator sells 1 one-off in-app purchase. GM shape asks for nothing beyond the download.

eCalculator ships an update every 3 months, GM shape every 12 months. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
