Put Alltrails app on your phone. It is free. Then find the trails area there. Then read the reviews, which may be within the last week or so and you will know the conditions of the trails.
For sure you can use any hiking app, especially one that you are familiar with.
I suggest SwitzerlandMobility because it will give you up to date information (rather than relying on week old reviews, if there are any). It is also a free app. It can be used for hiking, cycling, mountain biking, canoeing and winter sports like snowshoeing, cross-country skiing, hiking and sledding.
You will see all trail closures as well as the duration and reason for the closure. You can choose to have all train and bus stops shown, click on the one you want and you will be connected to the SBB schedule for that stop.
Zoom in on the map and you will see all of the small wanderweg routes near you - all of the little yellow lines are wanderweg paths.
Allow tracking to see exactly where you are as you hike. Pay the yearly fee (30 CHF or so) and you can draw your own routes, save photos at the exact location in which you took them, etc.
Whatever you decide to do, as a backup check something local - the Switzerland mobility web/app or local tourist websites to see which trails are open on the day you want to hike. This can save you from disappointment, or worse, especially in springtime when the conditions can change so quickly.
