Verdict
The clearest difference is monetization model: DayMarked at free against Freestyle Calculator's freemium. Freestyle Calculator's advantage is update cadence (every 3 days vs weekly) and ratings volume (8 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Freestyle Calculator sells 6 in-app purchases, starting at $0.99 per month and DayMarked sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Freestyle Calculator against 5.0 for DayMarked. That said, the two scores are not equally well evidenced: Freestyle Calculator has 8 ratings behind it against 1, so its average is the more settled of the two.
Freestyle Calculator ships an update every 3 days, DayMarked weekly. The most recent releases landed on September 19, 2026 and September 3, 2026 respectively.
