Verdict

The call

The clearest difference is update cadence: Teraverse at every 4 weeks against SpectrumGen's every 14 months. Teraverse also leads on rating (4.8 vs 4.4) and ratings volume (112 vs 10). SpectrumGen's advantage is price ($0.99 vs $2.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
