# HighBoost vs Converter

The clearest difference is in-app purchases: HighBoost at none against Converter's 6. HighBoost also leads on ads (none vs shown) and iOS requirement (11.0 vs 16.6). Converter's advantage is update cadence (weekly vs fortnightly). On price and device support there is nothing between them.

Both are free to download. Converter sells 6 in-app purchases, starting at $0.39 per 7 days. HighBoost asks for nothing beyond the download.

HighBoost ships an update fortnightly, Converter weekly. The most recent releases landed on November 7, 2026 and November 4, 2026 respectively.
