🌍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 app
Storky is a reliable and easy to use contraction timer with no ads created by Bibino, a baby monitoring app. With the Storky app, you can easily monitor the length of your contractions and intervals between them. The app gives you the idea of when the baby is coming to the world, so you know when to consider going to the hospital or a birth center.
SMART CONTRACTION TIMER
Start measuring the contraction with just one tap of a button. Once the contraction is over, tap the button again to stop the timer, and Storky will begin measuring the time of the interval.
