# Storage Unit Tracker vs Shelf

Storage Unit Tracker and Shelf are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Storage Unit Tracker sells 3 one-off in-app purchases and Shelf sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 10, 2026 and October 7, 2026 respectively.
