# iJuggle vs Frequency

The clearest difference is ads: iJuggle at none against Frequency's shown. iJuggle also leads on monetization model (free vs free with in-app purchases) and review sentiment (88% vs 73%). Frequency's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (340 vs 12). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iJuggle holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Frequency has 340 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 88% of iJuggle's written reviews are positive against 73% of Frequency's.

iJuggle ships an update every 3 months, Frequency fortnightly. The most recent releases landed on October 19, 2026 and October 18, 2026 respectively.
