Updated · How TGGET measures a niche
Verdict · confidence: medium
No niche: do not build
The decision is 'no' due to a declining demand trend (-45% YoY), a closed search landscape with zero weak SERPs, and expensive paid traffic ($14.46 CPC). The App Store is highly contested with 18 giants holding 38% of the market. While AI sub-niches show interest, the barrier to entry is too high for a new entrant without significant differentiation or existing audience.
- Demand: Medium monthly volume (1300) but declining trend (-0.45 YoY).
- Trend: Declining interest over the last year, with negative growth momentum.
- Stores: Contested market with 47 apps, 18 giants, and high median ratings (3876).
- Search: Closed SERPs; 0 out of 3 checked queries are weak, dominated by established SaaS and apps.
- Economics: Expensive CPC ($14.46) makes paid acquisition risky with low conversion assumptions.
- Entry: No specific entry point identified due to high competition across all channels.
