Tubi
Tubi is a free, ad-supported streaming service. The business model depends entirely on keeping you watching. The interface is more aggressive about autoplay and recommendations than paid competitors.
Why this score
Free + ad-supported means the incentive is pure watch time. Autoplay is aggressive. The home screen is algorithmically ranked to maximize the chance you'll start something.
Push notifications are frequent. The content library is large and undiscriminating, which means the algorithm does most of the choosing.
The breakdown
- Attention Capture6.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation4.0
Mechanics designed to bring you back — streak coercion, default push notifications, and re-engagement of dormant users.
- Social Pressure1.0
How much the experience exploits social psychology — public metrics, profile curation, and status comparison against others.
- Time Theft7.0
Mechanics that steal more time than you intended to give — no stopping cues, short units, and 'just one more' loops.
- Cognitive Erosion1.0
Mechanics that replace your independent thinking, memory, or judgment — creating dependency on the tool to function.
- Cognitive Nourishment1.0
Whether the app actively strengthens your ability to think for yourself. Shown on the label, but it does not affect the score.
