Daylight Goals's answer
Daylight Goals is the first app released on the app store focused on getting you to spend more time outdoors. It combines automatic time in daylight tracking with Apple Watch along with a sunlight timer live activity to allow you to easily keep track of how long you've been outdoors. Add to that notifications reminding you to get outdoors if you haven't been, and Peak UV notifications to know when the sun it at it's maximum potential.
YieldStack's answer:
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Daylight Goals's answer
Most sun apps are just focused on sunrise/sunset times. A few others show UV data. And a few more show your time in daylight. Daylight Goals brings them all together in one place to help you make sense of the data.
YieldStack's answer:
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.

Daylight Goals's answer
I came up with the idea during WWDC of 2023 when Apple announced that it was adding Time in Daylight tracking to the Apple Watch. I wanted to increase my time spent outside, so I set out to work on a simple app to push myself to go outside.
YieldStack's answer:
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
