# PhoneIoT vs Knowt

The clearest difference is review sentiment: PhoneIoT at 100% against Knowt's 63%. PhoneIoT also leads on in-app purchases (none vs 32) and ads (none vs shown). Knowt's advantage is ratings volume (11K vs 4) and chart position (#84 vs unranked). On price, update cadence and device support there is nothing between them.

Both are free to download. Knowt sells 28 in-app purchases, starting at $5.99 per month. PhoneIoT asks for nothing beyond the download.

PhoneIoT holds the better App Store score, 5.0 against 4.7.
