Verdict
The clearest difference is rating: TDRoom at 5.0 against CAD Smart Modeling's 3.5. TDRoom also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 5 months). CAD Smart Modeling's advantage is ratings volume (10 vs 1) and device support (4 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. TDRoom sells 1 in-app purchase, starting at $7.99 per month and CAD Smart Modeling sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
TDRoom holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: CAD Smart Modeling has 10 ratings behind it against 1, so its average is the more settled of the two.
TDRoom ships an update every 3 weeks, CAD Smart Modeling every 5 months. Both last shipped on November 4, 2026.
