# iTech Duo vs 3+ PRO

iTech Duo and 3+ PRO both sit at 3.7 stars, but that hides the real split: 43% of 3+ PRO's written reviews are positive against 34% of iTech Duo's. iTech Duo's advantage is iOS requirement (9.0 vs 11.0). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iTech Duo holds the better App Store score, 3.7 against 3.6. Both are backed by a comparable volume of ratings — 266 and 576 respectively. Written reviews complicate that: 34% of iTech Duo's written reviews are positive against 43% of 3+ PRO's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 14, 2026 and October 16, 2026 respectively.
