# LINK vs DVB

The clearest difference is in-app purchases: LINK at none against DVB's 1. LINK also leads on device support (3 vs 1) and iOS requirement (13.4 vs 17.0). DVB's advantage is update cadence (every 5 days vs every 2 months). On price and ads there is nothing between them.

Both are free to download. DVB sells 1 one-off in-app purchase. LINK asks for nothing beyond the download.

LINK ships an update every 2 months, DVB every 5 days. The most recent releases landed on October 25, 2026 and October 19, 2026 respectively.
