Verdict
The clearest difference is price: Apparatus App at Free against iWriter Pro's $5.99. Apparatus App also leads on rating (5.0 vs 4.7) and iOS requirement (8.0 vs 26). iWriter Pro's advantage is ratings volume (132 vs 1) and review sentiment (68% vs 50%). On update cadence, ads, in-app purchases and monetization model 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
Apparatus App is free to download; iWriter Pro costs $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Apparatus App holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: iWriter Pro has 132 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of iWriter Pro's written reviews are positive against 50% of Apparatus App's, so the app with the better star average is not the one people write more warmly about.
iWriter Pro ships an update every 3 months, Apparatus App every 2 months. The most recent releases landed on October 26, 2026 and October 19, 2026 respectively.
