Verdict
The clearest difference is rating: Code Red at 5.0 against Mayday's 3.9. Mayday's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (17 vs 1). On price, ads, in-app purchases and device support 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. Mayday sells 2 in-app purchases, starting at $7.00 per month and Code Red sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.
Code Red holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Mayday has 17 ratings behind it against 1, so its average is the more settled of the two.
