Merriman Market Timing iOS
A niche trading tool that pays for itself
iOS app detecting market reversal scores via weighted historical values for DJIA, Nasdaq, Gold, and Silver. Built on 40+ years of data.
> the problem
I got into financial market timing through a weekend seminar in Detroit. I flew out on a whim to study with Ray Merriman, widely considered the godfather of financial astrology. His market timing research is the best in the world, backed by 50+ years of historical data. I loved the community, saw that the field had no modern tools to put this research in traders' hands, and built one.
> the approach
Same process I used for Affirm Me. Designed the full UX in Figma, workshopped the concept, then built it in SwiftUI with a Supabase/PostgreSQL backend. The app delivers solar-lunar reversal scores, historical correlation data, and short-term trading signals based on 50+ years of daily price movements across DJIA, Nasdaq, Gold, and Silver.
> the lessons
The app has been generating $2–3k/month in recurring revenue for 18 months. Not bad for a side project with a niche audience. Technically, the biggest learning was in PostgreSQL database design and discovering the performance limits of Supabase's database access layer. Sometimes the most valuable lesson is knowing what not to use next time.
