Verdict
The clearest difference is review sentiment: MailZ at 100% against ChatKeyPT's 50%. MailZ also leads on ratings volume (54 vs 2). ChatKeyPT's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price 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. MailZ sells 8 in-app purchases, starting at $5.99 per month. ChatKeyPT asks for nothing beyond the download.
ChatKeyPT holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MailZ has 54 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of ChatKeyPT's written reviews are positive against 100% of MailZ's, so the app with the better star average is not the one people write more warmly about.
