# Kolt vs SubZen

The clearest difference is ads: SubZen at none against Kolt's shown. SubZen also leads on iOS requirement (16.4 vs 18.6). Kolt's advantage is update cadence (every 6 days vs fortnightly) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Kolt sells 3 in-app purchases, starting at $2.99 per month and SubZen sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Kolt ships an update every 6 days, SubZen fortnightly. The most recent releases landed on October 11, 2026 and October 12, 2026 respectively.
