# DWSIM Simulator vs Simple Harmonic Motion Calc

The clearest difference is price: DWSIM Simulator at Free against Simple Harmonic Motion Calc's $2.99. DWSIM Simulator also leads on update cadence (every 6 weeks vs every 28 months) and ratings volume (105 vs 2). Simple Harmonic Motion Calc's advantage is in-app purchases (none vs 10) and rating (5.0 vs 4.6). On ads and device support there is nothing between them.

DWSIM Simulator is free to download; Simple Harmonic Motion Calc costs $2.99 up front. DWSIM Simulator sells 10 one-off in-app purchases. Simple Harmonic Motion Calc asks for nothing beyond the download.

Simple Harmonic Motion Calc holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: DWSIM Simulator has 105 ratings behind it against 2, so its average is the more settled of the two.

DWSIM Simulator ships an update every 6 weeks, Simple Harmonic Motion Calc every 28 months. The most recent releases landed on October 1, 2026 and September 24, 2026 respectively.
