Max size of WebSQL/SQLite database inside UIWebView (phonegap)
Yes, the WebKit DB is also limited to 5mo.
You can trick the system with this solution: https://issues.apache.org/jira/browse/CB-330?focusedCommentId=13237796&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13237796
Or you can use a native SQLite DB (same as WebSQL) with a phonegap plugin. That plugin save the database in the Document folder (or you can specify another folder), and there is no size limit and data is saved by iCloud. (But take care, Apple don't really like apps wasting iCloud storage)
Here is the Native SQLite phonegap plugin : https://github.com/davibe/Phonegap-SQLitePlugin Regarding this plugin, there are some differences between the WebSQL API, here is an adaptor: https://gist.github.com/2009518
And if the data are important, you should save it to a server. I wrote a small lib to synchronize the SQlite DB to a server : https://github.com/orbitaloop/WebSqlSync
