# RIFE Frequency Amplifier vs KO Flow

The clearest difference is review sentiment: KO Flow at 100% against RIFE Frequency Amplifier's 27%. KO Flow also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). RIFE Frequency Amplifier's advantage is ratings volume (139 vs 2) and iOS requirement (13.0 vs 16.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. RIFE Frequency Amplifier sells 2 one-off in-app purchases 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: RIFE Frequency Amplifier has 139 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 27% of RIFE Frequency Amplifier's written reviews are positive against 100% of KO Flow's.
