Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 刺猬英语：剑桥KET/PET，初中英语备考神器 sells 10 one-off in-app purchases and 乐学同步单词 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
刺猬英语：剑桥KET/PET，初中英语备考神器 holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: 刺猬英语：剑桥KET/PET，初中英语备考神器 has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 29% of 刺猬英语：剑桥KET/PET，初中英语备考神器's written reviews are positive against 44% of 乐学同步单词's, so the app with the better star average is not the one people write more warmly about.
