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. 4Plan Home & Interior Planner sells 2 in-app purchases, starting at $9.99 per month. Ruler∘ asks for nothing beyond the download.
4Plan Home & Interior Planner holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: 4Plan Home & Interior Planner has 3K ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 50% of Ruler∘'s written reviews are positive against 46% of 4Plan Home & Interior Planner's, so the app with the better star average is not the one people write more warmly about.
Ruler∘ ships an update every 2 weeks, 4Plan Home & Interior Planner fortnightly. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
