# Bolt Exchange vs 키보드으

The clearest difference is in-app purchases: Bolt Exchange at none against 키보드으's 5. Bolt Exchange also leads on iOS requirement (13.0 vs 15). 키보드으's advantage is ads (none vs shown) and update cadence (every 5 days vs every 19 months). On price, rating and device support there is nothing between them.

Both are free to download. 키보드으 sells 5 one-off in-app purchases. Bolt Exchange asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Bolt Exchange against 5.0 for 키보드으. That said, the two scores are not equally well evidenced: 키보드으 has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 73% of Bolt Exchange's written reviews are positive against 97% of 키보드으's.

Bolt Exchange ships an update every 19 months, 키보드으 every 5 days. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
