Shopalarm

Shopalarm is a location-aware iOS app that turns ordinary reminders into timely nudges. Link a reminder to a specific store, such as Gamma, or an entire store category, such as any hardware store, and get alerted when you’re near a relevant location.

Brewbro Perfect your brews.

Brewbro turns espresso trial and error into repeatable recipes—especially when you rotate between different beans. Take a photo of your Sage Touch display to capture its settings, save what worked and return to the same bean weeks later without starting over.
