Famous last words, those are, in that strange world of gaming where we can die again and again. Mr Jump is really, really hard.

Verdict
The clearest difference is ads: James Summer at none against Mr Jump's shown. James Summer also leads on monetization model (free vs free with in-app purchases) and rating (4.7 vs 4.4). Mr Jump's advantage is ratings volume (4.2K vs 9) and update cadence (every 10 days vs every 6 weeks). On price, review sentiment, in-app purchases and device support there is nothing between them.
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. Mr Jump sells 10 one-off in-app purchases and James Summer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
James Summer holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Mr Jump has 4.2K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 82% of Mr Jump's written reviews are positive against 78% of James Summer's, so the app with the better star average is not the one people write more warmly about.
Mr Jump ships an update every 10 days, James Summer every 6 weeks. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
