Fitness health/apps: Export personal data from phone (i.e Dafit)
Though i haven't found specific apps I found method for &quot;powerusers&quot;.
Dafit stores its information in plain text inside a SQlite database files, there are several tables with apparently no relationship (maybe from code there are few relations).
How to extract/process the data:

Extract data file from Android


Option1. Find the data folder (from android), copy&amp;paste to accessible folder ¿root req?
Option2. Do a backup (titanium backup, oandbackup,...) and unzip the content of backup to a folder


Open file with a SQLlite tool
Export to spreadsheet/excel tables and process/transform there
Process/transform using SQL queries.
