# Fast vs Empty

The clearest difference is review sentiment: Fast at 75% against Empty's 0%. Fast also leads on rating (4.7 vs 1.0) and ads (none vs shown). Empty's advantage is update cadence (every 10 days vs every 2 months) and iOS requirement (15.2 vs 18.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Fast sells 8 in-app purchases, starting at $4.99 per month and Empty sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Fast holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Fast has 3.3K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 75% of Fast's written reviews are positive against 0% of Empty's.

Fast ships an update every 2 months, Empty every 10 days. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
