# KeyShade vs OBD Quest

The clearest difference is ads: KeyShade at none against OBD Quest's shown. OBD Quest's advantage is update cadence (every 3 weeks vs every 10 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. KeyShade sells 4 one-off in-app purchases and OBD Quest sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

KeyShade ships an update every 10 months, OBD Quest every 3 weeks. The most recent releases landed on September 24, 2026 and October 2, 2026 respectively.
