# DWSIM Simulator vs AIChE

The clearest difference is review sentiment: AIChE at 100% against DWSIM Simulator's 57%. AIChE also leads on in-app purchases (none vs 10) and rating (5.0 vs 4.6). DWSIM Simulator's advantage is ads (none vs shown) and ratings volume (105 vs 4). On price, monetization model and device support there is nothing between them.

Both are free to download. DWSIM Simulator sells 10 one-off in-app purchases. AIChE asks for nothing beyond the download.

AIChE 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 4, so its average is the more settled of the two. Written reviews point the same way: 57% of DWSIM Simulator's written reviews are positive against 100% of AIChE's.
