Verdict
The clearest difference is ratings volume: PunchLab at 809 against KO Flow's 2. KO Flow's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 9 days). 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. PunchLab sells 9 in-app purchases, starting at $17.99 per month and KO Flow sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
KO Flow holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PunchLab has 809 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 86% of PunchLab's written reviews are positive against 100% of KO Flow's.
PunchLab ships an update every 9 days, KO Flow every 3 days. The most recent releases landed on October 26, 2026 and October 29, 2026 respectively.
