# CONVERT UNITS vs Post

The clearest difference is ads: Post at none against CONVERT UNITS's shown. Post also leads on review sentiment (100% vs 76%) and rating (5.0 vs 4.7). CONVERT UNITS's advantage is ratings volume (1.4K vs 2) and monetization model (ad-supported vs free with in-app purchases). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. CONVERT UNITS sells 2 in-app purchases, starting at $0.99 per month and Post sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Post holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CONVERT UNITS has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 76% of CONVERT UNITS's written reviews are positive against 100% of Post's.

CONVERT UNITS ships an update weekly, Post every 3 days. Both last shipped on October 20, 2026.
