# 發票怪獸 vs 發票收集雞

The clearest difference is rating: 發票怪獸 at 4.8 against 發票收集雞's 1.0. 發票怪獸 also leads on ratings volume (45 vs 1). 發票收集雞's advantage is ads (none vs shown) and review sentiment (80% vs 50%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 發票怪獸 sells 7 one-off in-app purchases and 發票收集雞 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

發票怪獸 holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: 發票怪獸 has 45 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of 發票怪獸's written reviews are positive against 80% of 發票收集雞's, so the app with the better star average is not the one people write more warmly about.

發票怪獸 ships an update fortnightly, 發票收集雞 every 5 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
