# E vs MQTT

The clearest difference is in-app purchases: E at none against MQTT's 2. E also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 16 months). On price and device support there is nothing between them.

Both are free to download. MQTT sells 2 one-off in-app purchases. E asks for nothing beyond the download.

E ships an update every 5 weeks, MQTT every 16 months. The most recent releases landed on September 20, 2026 and September 14, 2026 respectively.
