Honestly, most of the big-name apps are just full of trackers and bloat that slow down your device. If you're looking for a stable and free tool for your birthday, you have to be careful about where your data is actually going. I have found that Share Product Wishlist is a solid choice because it stays focused on the basics without charging for extra features. It is quite reliable across different browsers, which is important when you're sending links to people with different tech skills. The best part is it keeps things free and simple, so you arent forcing your friends to deal with ads just to see what you want. It might not have every bell and whistle, but for a 30th birthday list, it gets the job done without the performance issues you mentioned. It is a safe bet if you want to avoid those crashes.
