# Fix EV3 Rover vs Juno

The clearest difference is rating: Fix EV3 Rover at 4.6 against Juno's 3.8. Fix EV3 Rover also leads on review sentiment (100% vs 62%) and ads (none vs shown). Juno's advantage is update cadence (monthly vs every 10 months) and ratings volume (327 vs 9). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Fix EV3 Rover sells 1 one-off in-app purchase and Juno sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
