| Daqri shuts down, Apple introduces a subscription grace period and SmileDirectClub goes public. Here's your Daily Crunch for September 13, 2019. 1.

Daqri is the latest heavily funded, enterprise-focused augmented reality startup to struggle or shut down recently, with Osterhout Design Group unloading its AR glasses patents earlier this year and Meta selling its assets after it ran out of cash. 
2. Apple introduces a 'grace period' for lapsed App Store subscriptions Previously, any lapse in payment could cut off the customer from an app's subscription-based features.

SmileDirectClub makes its debut on the public market Teeth-straightening company SmileDirectClub rang the opening bell at Nasdaq yesterday, marking its first day of trading as a public company. 4.

Walmart's Vudu adds Family Play feature so viewers can skip sex, violence and substance abuse Vudu viewers can turn filters on and off for sex/nudity, violence, substance abuse and language.

Sidewalk Labs spins out urban data-gathering tool Replica into a company The Replica tool grew out of Model Lab, a project started two years ago to investigate modeling as a way to address urban problems — specifically the fact that public agencies don't have all the information needed to understand the connections between transportation and land use. 7. How the Valley can get philanthropy right with former Hewlett Foundation president Paul Brest When he was named president of the William & Flora Hewlett Foundation, Brest applied the rigor of a legal scholar, not just to his own institution's practices, but to those of the philanthropy field at large.
