NEURODICE β DICE MAGIC WITHOUT ANY DICE Created by professional mentalist Paul Brook, NeuroDice is a precision-engineered mentalism tool that works with imaginary (or βinvisibleβ) dice. It transforms thought-of dice rolls into powerful, impossible predictions, allowing you to perform your existing routines without any physical dice or supercharge the ones that do use them. VARIOUS INPUT METHODS Use your iPhone keyboard, a Bluetooth remote, or your voice to secretly input information directly into the app. PREDICTION NOTE OR IN-APP DATA Receive the information inside the app, or let NeuroDice automatically create a hidden prediction in Notes that reveals the exact dice values your participant is thinking of...all without ever touching a real die.

Verdict
The clearest difference is in-app purchases: L4D at none against NeuroDice's 7. L4D also leads on iOS requirement (16.0 vs 18.4). NeuroDice's advantage is price ($24.99 vs $29.99). On update cadence, ads and device support there is nothing between them.
