Soundiverse is a serious game filled with colourful visuals, engaging soundscapes, and playful mechanics. Children are tasked to play for approximately 12 minutes a day, five days a week, for 10 weeks. This may enhance their listening skills, slowly encouraging their brains to adapt to more difficult listening scenarios. Difficulty levels are adaptive to suit each child's unique needs.

Verdict
The clearest difference is ads: Soundiverse at none against SignChat's shown. Soundiverse also leads on iOS requirement (16.3 vs 18.2). SignChat's advantage is update cadence (weekly vs every 4 weeks). On price, in-app purchases and device support there is nothing between them.
