Verdict
The clearest difference is monetization model: Cedarfalls Slips at free with in-app purchases against DriverMonitor's subscription. DriverMonitor's advantage is update cadence (every 6 weeks vs every 10 months) and ratings volume (19 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. DriverMonitor sells 5 in-app purchases, starting at $19.99 per month and Cedarfalls Slips sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for DriverMonitor against 5.0 for Cedarfalls Slips. That said, the two scores are not equally well evidenced: DriverMonitor has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
DriverMonitor ships an update every 6 weeks, Cedarfalls Slips every 10 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
