"Thorium" app details how thorium can be transformed into energy. Nuclear bonds contains a million times the energy of chemical bonds. Thorium is abundant. Thorium can be converted into energy through nuclear fission. When doing so, thorium produces far less long-lived nuclear waste than fissioning uranium in today's reactors. A series of educational videos first introduce thorium and the concept of fission, then contrast the use of thorium in a Molten Salt Reactor (MSR) against today's reactors, solar and wind.

Verdict

The call

Thorium and VisualMind both sit at 4.5 stars, but that hides the real split: 67% of Thorium's written reviews are positive against 23% of VisualMind's. Thorium also leads on in-app purchases (none vs 10) and iOS requirement (8.2 vs 16.4). VisualMind's advantage is ratings volume (3.3K vs 2) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and device support there is nothing between them.
