Updated · How TGGET measures a niche

Verdict · confidence: medium

Possible niche: validate

The ebook reader market is declining (-62% YoY) and dominated by giants like Kindle and Libby with high competition in stores. While search SERPs show some weakness (1 weak out of 3 checked), the entry point 'ebook reader kindle app' has high demand but is controlled by Amazon. The verdict is 'maybe' because while there is a clear pain point (UI changes, ads), the declining trend and high customer acquisition costs make it risky without a specific niche focus.

  • Demand: Monthly search volume is 1,000 with a declining trend of -0.62 YoY.
  • Trend: Year-over-year change is -0.62, indicating a shrinking market interest.
  • Stores: Competition is 'crowded' with 10 giants holding 21% share and median ratings of 208.
  • Search: 1 out of 3 checked SERPs is weak, but the primary entry phrase is dominated by a single product competitor.
  • Economics: CPC is $2.83 (average), which is moderate, but paid apps are scarce (only 3), suggesting reliance on ad-supported models.

2. Napkin economics

Price

$4.99 one-time or $2.99/month

Does it add up

Customer acquisition cost

$14.15 (assuming 20% conversion rate from click to install, based on $2.83 CPC)

Paid search: CPC $2.83 · bids $1.00–$3.89 · competition: Low

Revenue per customer

$15.00 (assuming $5 price and 30% retention over 6 months)

Assumptions to validate:

  • 20% conversion rate from click to install.
  • 30% retention rate over 6 months.
  • Price point of $4.99 is acceptable to users.
  • No ad revenue, relying on purchases.
  • Development cost is covered by initial seed.
