3. What are we talking about ? Ultimately : Business – technology driven ! 08/07/15 https://orga.zone - twitter : @ orgaralf 3

4. Why are we talking about that ? Because we want to be independent Because not every app needs to be native ( you are using JS anyhow ) Because Apple, Google, Facebook and Microsoft are in control , not you 08/07/15 https://orga.zone - twitter : @ orgaralf 4

5. How to use the Cache Manifest Using the AppCache loads everything into the browsers cache – but the server needs to know the MIME type Apache: AddType text /cache-manifest . appcache HTML: < html manifest=" orga.appcache " > File: 08/07/15 https://orga.zone - twitter : @ orgaralf 5

6. 08/07/15 https://orga.zone - twitter : @ orgaralf 6 It is offline, but still there Your „web app “ keeps working

7. 08/07/15 https://orga.zone - twitter : @ orgaralf 7 Continue in that mindset ... Adding „ LocalStorage “ Adding „Add This To Homescreen “

8. 08/07/15 https://orga.zone - twitter : @ orgaralf 8 Continue in that mindset ... Now we have : An app loaded from the web All Javascript , CSS and HTML locally without the web An icon on the Homescreen of the smartphone , that looks native HTML5 local storage with up to 25 MB of space as a database That is enough to do meeting organizing , time recording , travel reports and even city guides , simple games , resource management , drivers‘s logbooks , etc.
