# INTVL vs Rocket

The clearest difference is rating: INTVL at 4.7 against Rocket's 1.0. INTVL also leads on ratings volume (5.6K vs 1) and chart position (#45 vs unranked). Rocket's advantage is ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. INTVL sells 12 in-app purchases, starting at $7.99 per month and Rocket sells 2 in-app purchases, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

INTVL holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: INTVL has 5.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 83% and 83% positive.

INTVL ships an update every 6 days, Rocket every 5 days. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
