Verdict
The clearest difference is rating: SendMan at 5.0 against WriteAfy's 4.2. SendMan also leads on ads (none vs shown) and review sentiment (100% vs 75%). WriteAfy's advantage is ratings volume (5 vs 1). On price, update cadence and in-app purchases 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. WriteAfy sells 3 in-app purchases, starting at $3.99 per month and SendMan sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
SendMan holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: WriteAfy has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of WriteAfy's written reviews are positive against 100% of SendMan's.
WriteAfy ships an update every 8 days, SendMan every 2 weeks. The most recent releases landed on November 14, 2026 and November 15, 2026 respectively.
