Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Hotviewer（WIFI Microscope） holds the better App Store score, 3.0 against 2.7. That said, the two scores are not equally well evidenced: i has 35 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 0% of Hotviewer（WIFI Microscope）'s written reviews are positive against 20% of i's, so the app with the better star average is not the one people write more warmly about.
Hotviewer（WIFI Microscope） ships an update every 3 months, i every 14 months. The most recent releases landed on September 17, 2026 and September 18, 2026 respectively.
