Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Constant Contact holds the better App Store score, 4.8 against 1.2. That said, the two scores are not equally well evidenced: Constant Contact has 11K ratings behind it against 101, so its average is the more settled of the two. Written reviews point the same way: 34% of Constant Contact's written reviews are positive against 3% of Supra One's.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
