An app for divorcing parents to seal records, $17.99/month; you need paid acquisition skills or a lawyer channel

The demand is real, but anyone can have the idea. The winners are the ones who can buy traffic; without a channel, don't build the 17th sealed-journal app.A single sample, and that sample is an ad agency: Documented runs attribution on Meta, TikTok, Google and Bing, plus 109 SEO pages. In the same year, 15 same-style apps added up to 61 US ratings, while ProofLog, which discloses revenue, made $90 in a year. Anyone with paid-acquisition, lawyer or SEO channels could run it as a four-week experiment.Maybe · grade and headline based on the full write-up · next review 12-01

Background	Divorcing parents need records written at the time to show lawyers and judges. Documented is listed for 8-19, with on-the-spot sealing + third-party timestamps
Upside	A one-sided record the other party doesn't know about. Legacy platforms are court-appointed shared communication tools and won't quietly log for one side
Demand	Save on lawyer hourly fees: the other side doesn't know, texts get sealed in as-is, PDF export can't have errors, and good days get recorded too
Competition	At least 16 same-type apps a year, 15 totaling 61 ratings; Alimentor has been doing it since 2018 ($6.99 one-time purchase, 1,321 ratings) 2
Revenue	Documented sits at #104–#146 in the US productivity Top Grossing. Estimated revenue is $1.5–40k a month before ad spend. ProofLog: $90 over 12 months.
Growth	Performance ads: Meta, TikTok, AppsFlyer, Google (10-29), Bing (10-25) + 109 SEO pages. Similar PH launches got 0–3 votes
Window	Ignore features and look at ad prices: bids on custody keywords rise as more advertisers push; SEO takes months before it drives traffic
Who it's for	For those who can do UGC paid acquisition, know a family-law attorney, or can write long-tail state-law SEO. Indie devs who just want to list and wait for organic traffic should skip it.
