Verdict

The call

The clearest difference is rating: Spotr at 4.7 against Rack's 3.9. Spotr also leads on update cadence (every 2 days vs every 11 days) and ratings volume (640 vs 11). Rack's advantage is monetization model (freemium vs subscription) and review sentiment (86% vs 61%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Spotr sells 15 in-app purchases, starting at $3.99 per month and Rack sells 7 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Spotr holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Spotr has 640 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 61% of Spotr's written reviews are positive against 86% of Rack's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Spotr ships an update every 2 days, Rack every 11 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
