Verdict
The clearest difference is rating: Postfun at 4.4 against Letteringo's 1.0. Postfun also leads on ratings volume (61 vs 1) and monetization model (ad-supported vs free with in-app purchases). Letteringo's advantage is ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Postfun sells 2 in-app purchases, starting at $2.99 per month and Letteringo sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Postfun holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Postfun has 61 ratings behind it against 1, so its average is the more settled of the two.
Postfun ships an update every 6 weeks, Letteringo every 3 weeks. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
