# Wi vs Robotics

The clearest difference is rating: Wi at 3.9 against Robotics's 2.3. Wi also leads on review sentiment (36% vs 13%). Robotics's advantage is in-app purchases (none vs 3) and ratings volume (241 vs 27). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Wi sells 3 one-off in-app purchases. Robotics asks for nothing beyond the download.

Wi holds the better App Store score, 3.9 against 2.3. That said, the two scores are not equally well evidenced: Robotics has 241 ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 36% of Wi's written reviews are positive against 13% of Robotics's.

Wi ships an update every 3 months, Robotics every 5 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
