# Peak vs CueRack

The clearest difference is price: Peak at Free against CueRack's $4.99. Peak also leads on iOS requirement (15.0 vs 18.6). CueRack's advantage is ads (none vs shown) and update cadence (weekly vs fortnightly). On in-app purchases and device support there is nothing between them.

Peak is free to download; CueRack costs $4.99 up front. Peak sells 10 in-app purchases, starting at $2.99 per month and CueRack sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Peak ships an update fortnightly, CueRack weekly. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
