The L.U.I.S., or Loadable User Interface System app relies on HTML5-formatted data to present the user with configuration pages sent by Tibbo devices. A simple-to-use library that adds L.U.I.S. support to your Tibbo BASIC/C app is also available.

Verdict
The clearest difference is update cadence: LUIS at every 4 months against Multinomial's every 47 months. LUIS also leads on iOS requirement (8.0 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
