# Ekofluid vs Calculator

The clearest difference is in-app purchases: Ekofluid at none against Calculator's 1. Ekofluid also leads on ads (none vs shown). Calculator's advantage is update cadence (daily vs every 6 months) and iOS requirement (12.0 vs 14.0.0). On price and device support there is nothing between them.

Both are free to download. Calculator sells 1 one-off in-app purchase. Ekofluid asks for nothing beyond the download.

Ekofluid ships an update every 6 months, Calculator daily. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
