Verdict

The call

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.
