# Dark Sky Alumni Unveil Acme Weather's Fresh Forecast Approach
Former Dark Sky developers have launched Acme Weather, a groundbreaking iPhone app that revolutionizes weather forecasting by offering transparent alternate predictions instead of a single "best guess," addressing the inherent uncertainty in weather data.[1][2][3] This bootstrapped venture by ex-Apple team members, including co-founders Adam Grossman, Josh Reyes, and Dan Abrutyn, promises hyper-local accuracy enhanced by crowdsourced reports, advanced notifications, and privacy-focused design, marking a bold return three years after Apple's shutdown of the beloved Dark Sky app.[1][2][3]
Acme Weather's Innovative Alternate Forecasts
Acme Weather sets itself apart by rejecting traditional single-prediction models, instead displaying a range of potential outcomes to better reflect weather's chaotic nature.[1][2][3] Developed using homegrown forecasts that integrate numerical weather prediction models, satellite data, ground station observations, and radar, the app visualizes forecast confidence through tight or wide groupings of prediction lines—narrow spreads signal reliability, while broader ones warn of rapid changes.[3] Co-founder Adam Grossman emphasized this transparency in his blog, noting that "forecasts are often wrong" due to weather's instability, making Acme a superior evolution of Dark Sky's hyper-local tech.[1][3]
The app also incorporates crowdsourced user reports for real-time local conditions, alongside interactive maps for precipitation, lightning, cloud cover, and more, empowering users to plan with fuller context.[1]
From Dark Sky to Apple and Back: The Team's Journey
Acquired by Apple in March 2020, Dark Sky was discontinued in January 2023, with its features folded into Apple's native Weather app and WeatherKit API.[1][2] The original team, however, departed to pursue experimental ideas stifled by Apple's scale, long development cycles, and stakeholder demands, as Grossman explained: "In a big company... mistakes are costly."[2] Now independent and bootstrapped with a mix of Dark Sky veterans and new hires, the small team launched Acme Weather on iOS, with an Android version in the works.[2][3]
Grossman praised their Apple tenure but highlighted the freedom to innovate outside it, positioning Acme as a more reliable forecast system than even Dark Sky offered.[2]
Key Features and User Benefits
Acme Weather excels in notifications, delivering instant alerts for rain, severe weather, nearby lightning, collaborative reports, rainbows, and sunsets—blending utility with delight.[1][2] Its intuitive interface handles vast data without overwhelming users, earning praise for navigability from outlets like 9to5Mac.[1] Privacy is paramount: the app collects only essential data for forecasts, avoids location history storage, user data sales, or third-party trackers.[3]
Priced at a free two-week trial followed by $25/year subscription, Acme targets consumers while hinting at potential developer APIs, echoing Dark Sky's past offerings.[2][3]
Future Outlook and Industry Impact
As a bootstrapped project, Acme Weather could disrupt weather apps by prioritizing transparency and reliability, potentially extending to developer tools amid growing demand for accurate data.[2] Initial impressions highlight its edge over apps stuck on singular forecasts, positioning it as a valuable alternative in a crowded market.[1]
