Progressive Web Apps aim to bring the benefits of native mobile apps to the web. They use newer web capabilities like app manifests and service workers to deliver app-like experiences through the browser. App manifests allow web apps to be installed on home screens and launched full screen like native apps. Service workers enable features like offline access and push notifications. Early adopters are seeing increased user engagement through Progressive Web Apps, with metrics like conversions and time spent improving. While browser support is still evolving, Progressive Web Apps provide a promising approach for delivering high-quality mobile experiences through the web.

- 40. 🌍 So, back to the web?
- 41. 🛠 Yes, but with a twist…
- 42. ⚠ We weren’t ready to go all out on web with mobile.
- 43. 💾 🌧 Instead of creating web sites that work well on mobile, we packaged them up and submitted them to market places. 🌧 In a 1:1 comparison with native apps, they looked rubbish. 🌧 That’s because they weren’t web products, but native apps built in web technologies.

- 46. Let’s tackle the mobile form factor… 🤔
- 47. ✏ Small initial payload ✏ Form factor supporting content ✏ Form factor supporting interfaces ✏ Offline/Flaky connection support ✏ Taking advantage of the power of the end user device ✏ Avoiding interaction latency ❤📲
- 48. The best way to bend the retention curve is to target the first few days of usage, and in particular the first visit. That way, users set up themselves up for success. http://andrewchen.co/new-data-shows-why-losing-80-of-your-mobile-users-is-normal-and-that-the-best-apps-do-much-better/ “

- 63. Great, but what about support? 🤔
- 64. What we’re talking about here is progressive enhancement
- 65. Using this, we can support the past…
- 66. And we can support current edge cases…
- 67. And after some checking, all the current browsers and what they support…
- 68. Let’s talk about iOS… 🍏
- 69. There is no official timeline when or if ServiceWorker will be in iOS… 💔
- 70. iOS has 45% of the US smartphone market, and iOS users spend $1.08 per user per app per user vs $.43 on Android. https://medium.com/javascript-scene/why-native-apps-really-are-doomed-native-apps-are-doomed-pt-2-e035b43170e9#.axf46f08l “

- 78. 🆙 🔧 Any web product can become a Progressive Web App, not all have to be. 🔧 You’ll reap the rewards of simple maintenance and upgrade paths in the form factor mobile users expect. 🔧 Apps can hibernate and wake up on demand - no need to have the browser open.
- 79. 🔗 🙂 The great thing here is that progressive web apps bring back the power of the link 🙂 You don’t need to play by the rules of a closed marketplace 🙂 You can send people a link and by the time they looked at the app it is ready to use - it is real try before you buy.
- 80. In app purchases are where the money is at, and you can do that in your own app without splitting costs with Apple or Google. http://marketingland.com/app-purchases-dominate-ads-app-store-lifetime-revenue-hits-71-billion-183953 “
- 81. For all intents and purposes, PWAs are a good opportunity to slim down the web. ?
- 82. To find a good middle ground of control and user convenience…🎛
- 83. …without reinventing the great distribution model that is the web.🌍💝
