# One vs RackWatt

The clearest difference is review sentiment: RackWatt at 100% against One's 14%. RackWatt also leads on rating (5.0 vs 2.3) and update cadence (every 11 days vs monthly). One's advantage is ratings volume (188 vs 1) and iOS requirement (15.5 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. One sells 15 one-off in-app purchases and RackWatt sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

RackWatt holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: One has 188 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 14% of One's written reviews are positive against 100% of RackWatt's.

One ships an update monthly, RackWatt every 11 days. The most recent releases landed on October 27, 2026 and October 31, 2026 respectively.
