# E vs 多多发票

The clearest difference is in-app purchases: E at none against 多多发票's 8. E also leads on iOS requirement (13 vs 15.0). 多多发票's advantage is update cadence (every 5 days vs every 4 months) and device support. On price there is nothing between them.

Both are free to download. 多多发票 sells 8 one-off in-app purchases. E asks for nothing beyond the download.

E ships an update every 4 months, 多多发票 every 5 days. The most recent releases landed on October 5, 2026 and October 24, 2026 respectively.
