The report was written by a language model from the collected research data and may be inaccurate; each recommendation cites its source, verify it against the raw data. Generated 2026-09-29T10:00:48+00:00.
Data: search demand, search results, the App Store, public-interest and developer community signals. The verdict is computed by rules from these numbers; the explanation and the plan are written by a language model. Both are evidence to check, not a promise.
No, the numbers argue against it. TGGET scored “document signing app” -3 on a scale from -6 to +5. Against it: the app stores are crowded with large apps, search results are held by strong sites, paid traffic is expensive. The verdict is “No niche”.
TGGET measured 1,000 monthly searches for “document signing app” in the United States in September 2026. Search interest is about stable: -12% over a year.
0 of 3 checked search results are weak and 1 is strong. 49 competing apps were found in the App Store; 13 of them have more than 10,000 ratings, and the median app has 130 ratings.
A click in paid search costs about $10.32, and competitors in this niche charge for their products.
None of the phrases TGGET checked has weak search results, so there is no easy way in through search.
TGGET computes the verdict by rules from five measured factors: demand, its change over a year, competition in the app stores, the strength of the search results and the cost of paid traffic. Each factor adds or takes away points and the sum decides, so the same numbers always give the same answer. A language model writes the explanation and the plan; it does not choose the verdict.
