Verdict
The clearest difference is review sentiment: Kerflux at 96% against PPSSPP's 72%. Kerflux also leads on rating (4.8 vs 4.5) and update cadence (weekly vs every 4 weeks). PPSSPP's advantage is ratings volume (2.7K vs 331). On price, ads, in-app purchases and monetization model 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. Kerflux sells 4 one-off in-app purchases and PPSSPP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Kerflux holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: PPSSPP has 2.7K ratings behind it against 331, so its average is the more settled of the two. Written reviews point the same way: 96% of Kerflux's written reviews are positive against 72% of PPSSPP's.
Kerflux ships an update weekly, PPSSPP every 4 weeks. Both last shipped on October 20, 2026.
