The 4iiii app is a valuable tool to get the most out of the features of your 4iiii products and achieve your fitness goals. Using the app, you can connect to your 4iiii power meter (PRECISION 3/3+ models) and your Viiiiva heart rate monitor to both configure and update them. You can record workout data to be later uploaded to your favourite training software. The companion Ride Watch app turns your Apple Watch into a cycling head unit. View power, cadence, heart rate, speed, distance, live while riding. Ride records your workout data to FIT file, and to Apple Fitness for closing your rings. Auto-sync to Strava keeps your activity feed up-to-date on completion of every outdoor or indoor cycling workout.

Verdict
The clearest difference is ads: Moore Performance at none against 4iiii's shown. Moore Performance also leads on iOS requirement (9.0.0 vs 15.0). 4iiii's advantage is update cadence (every 3 months vs every 48 months). On price, in-app purchases and device support there is nothing between them.
