An interesting project, I liked to download it, but:

 - Dark Mode Please.
 - The design needs more work: I don't know, but it looks a bit old and doesn't have a lot of diagrams and comparisons.
 - Creativity: There are a lot of sites that provide the tracking feature without the risk of installing anything, so you will need to add more features.
 - Dark Mode Please.
 - Portable mode: If possible, it will be fine.
 - Dark Mode Please.

Then we can download and compare the performance/speed of updates.
