# Electrical Calculator lite vs NEMA Guide

The clearest difference is in-app purchases: NEMA Guide at none against Electrical Calculator lite's 2. NEMA Guide also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Electrical Calculator lite sells 2 one-off in-app purchases. NEMA Guide asks for nothing beyond the download.

Electrical Calculator lite ships an update every 5 weeks, NEMA Guide every 2 days. The most recent releases landed on September 27, 2026 and September 12, 2026 respectively.
