Lot of space wasted on the sides + App not centered vertically

[MedAzizTousli]

Nice app. Straightforward and intiuitive. I love it.
As a near-sighted person, I found difficulty reading the information on the page, and I noticed that there is a lot of empty space on the sides and below (the app is centered horizontally, but not centered vertically). I zoomed in twice with my browser and it fitted almost perfectly.
I recommend either a zoom in/out option controlled by the user, or a zoom in the app itself (at least once) to cover the big empty space on the sides, and to show the information on the page more clearly; while also considering centering the app vertically as well.
Keep up. Best regards.
