Verdict
The clearest difference is review sentiment: PlanForm at 100% against CADraw's 50%. PlanForm also leads on rating (5.0 vs 2.9) and monetization model (free vs free with in-app purchases). CADraw's advantage is ratings volume (10 vs 2) and iOS requirement (13.0 vs 15.0). On price, update cadence, ads 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. CADraw sells 6 in-app purchases, starting at $1.39 per month and PlanForm sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
PlanForm holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: CADraw has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of CADraw's written reviews are positive against 100% of PlanForm's.
CADraw ships an update fortnightly, PlanForm every 3 weeks. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
