Foxi was no ordinary fox - she had the unique ability to eat spam messages. Every day, Foxi would roam the digital landscape, prowling through emails and text messages in search of delicious spam. Whenever she found a spam message, she would gobble it up, leaving the inboxes of her human friends clean and free of clutter. Despite her love of spam, Foxi was not a selfish fox.

Both are free to download. SMS Shield sells 3 in-app purchases, starting at $0.99 per month and AI Spam Shield Text Blocker sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

SMS Shield holds the better App Store score, 3.2 against 2.3. That said, the two scores are not equally well evidenced: SMS Shield has 138 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 17% of SMS Shield's written reviews are positive against 38% of AI Spam Shield Text Blocker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SMS Shield ships an update fortnightly, AI Spam Shield Text Blocker every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
