# My Microphone vs Car Key

The clearest difference is rating: My Microphone at 4.2 against Car Key's 1.9. My Microphone also leads on ratings volume (1.7K vs 15) and update cadence (every 3 weeks vs every 4 months). Car Key's advantage is in-app purchases (none vs 13) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. My Microphone sells 13 in-app purchases, starting at $6.99 per 7 days. Car Key asks for nothing beyond the download.

My Microphone holds the better App Store score, 4.2 against 1.9. That said, the two scores are not equally well evidenced: My Microphone has 1.7K ratings behind it against 15, so its average is the more settled of the two.

My Microphone ships an update every 3 weeks, Car Key every 4 months. The most recent releases landed on October 29, 2026 and October 7, 2026 respectively.
