# DevInfo X vs Device Kit

The clearest difference is ads: Device Kit at none against DevInfo X's shown. Device Kit also leads on update cadence (every 10 days vs every 2 months) and rating (4.9 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. DevInfo X sells 2 one-off in-app purchases and Device Kit sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Device Kit holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Device Kit has 94 ratings behind it against 16, so its average is the more settled of the two.

DevInfo X ships an update every 2 months, Device Kit every 10 days. The most recent releases landed on October 31, 2026 and November 7, 2026 respectively.
