# Kaleidoscope vs Frequency

The clearest difference is review sentiment: Frequency at 73% against Kaleidoscope's 0%. Frequency also leads on rating (4.7 vs 3.8) and in-app purchases (none vs 3). Kaleidoscope's advantage is ads (none vs shown) and update cadence (daily vs fortnightly). On price, monetization model and device support there is nothing between them.

Both are free to download. Kaleidoscope sells 3 in-app purchases, starting at $3.99 per 7 days. Frequency asks for nothing beyond the download.

Frequency holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Frequency has 1.2K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 0% of Kaleidoscope's written reviews are positive against 73% of Frequency's.

Kaleidoscope ships an update daily, Frequency fortnightly. The most recent releases landed on October 30, 2026 and November 8, 2026 respectively.
