Complaints: overpriced ×1
Top positive
★★★★☆ Helpful But Overpriced
The app is simple to use. I don’t think it’s worth $4.99, however. It’s definitely overpriced for what it is. I don’t really use the journal feature and after hearing the baby cries and taking the quiz a couple times, I won’t use the app it…
Top negative
★★☆☆☆ Not worth it
Not worth the 4.99 to hear the cries. Not much else to do in the app.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
About this analysis
Why low confidence: only 7 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Dunstan Baby is a early-stage iOS app in the health & fitness space with weak public traction — only 7 ratings, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
