Value Logger

Your rating: None Average: 5 (4 votes)

Based on the original Value Logger by kimmoli.

The original one worked well on Jolla1 until my databases grew to thousands of entries and UI got painfully slow. Then I switched to a newer Sailfish OS device with a hi-res display and it turned out that sizes of many UI elements were hardcoded in pixels, some text labels became unreadable, fixed-resolution PNGs became too small and so on.

I had no choice but to fix it!

This app uses the same database file and the same schema as the original app, they are fully compatible in that respect. The package name was changed from harbour-valuelogger to harbour-valuelogger2 to avoid conflicts with Jolla Store. Overall it's pretty much the same thing with a few improvements such as:

  1. Optimized drawing
  2. Improved zooming
  3. Adapted to hi-res displays
  4. Full landscape support
  5. Compatibility with light ambiences
  6. Integration with My Backup
  7. And more...

I thought that this might be useful to other people too. Here we go.

This would be interesting combined with data sources, like stock markets, mineral prices, food prices, products prices, exchange rates,... There should exist plenty of good sources where the data could came from. Only thing the app would have to do, would be to get the data in preselected intervalls :)

I don't want to disappoint you, but it's rather unlikely that I'd do much beyond maintaining the original basic functionality and adding some visual and convenience improvements on top of it, like dashed lines, alighing grid lines at nice rounded values and such. This app already does more or less everything I need it to do))

Thanks for the update! The original was one of the oldest programs still in my daily use. Now I switched over to your improved version :)
