Verdict
The clearest difference is review sentiment: Freestyle Calculator at 100% against Air Codes's 73%. Freestyle Calculator also leads on rating (5.0 vs 4.7). Air Codes's advantage is ratings volume (435 vs 8). On price, update cadence, 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. Air Codes sells 12 one-off in-app purchases and Freestyle Calculator sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Freestyle Calculator holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Air Codes has 435 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 73% of Air Codes's written reviews are positive against 100% of Freestyle Calculator's.
Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on September 3, 2026 and September 19, 2026 respectively.
