My Device Info shows the specs and status of your iPhone or iPad in one place. See device name and model, iOS version, screen size, brightness, storage used and free, battery level, charging status, Low Power Mode, cameras, biometrics, and more. Tap a row for a short tip. Home Screen and Lock Screen widgets keep battery, free space, and other basics handy without opening the app. On Apple Watch, check name, model, watchOS, battery, and more at a glance. Free forever for the core info. Upgrade to Pro (one-time, no subscription) to remove ads and unlock extras like network details, Wi-Fi name, About This Model, history, and clean export (text, PDF, and image card). Simple. Useful. No fluff.

Verdict
The clearest difference is in-app purchases: KRA System at none against My Device Info!'s 1. KRA System also leads on ads (none vs shown) and iOS requirement (12.4 vs 16.0). On price and device support there is nothing between them.
