# Checklists App vs CostX

The clearest difference is review sentiment: CostX at 100% against Checklists App's 22%. CostX also leads on price (Free vs $0.99) and update cadence (every 4 weeks vs every 10 months). Checklists App's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.

CostX is free to download; Checklists App costs $0.99 up front. CostX sells 2 in-app purchases, starting at $1.99 per month. Checklists App asks for nothing beyond the download.

Checklists App holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: CostX has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 22% of Checklists App's written reviews are positive against 100% of CostX's, so the app with the better star average is not the one people write more warmly about.

Checklists App ships an update every 10 months, CostX every 4 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
