Since Lunala will be back soon I figured I'd share this little trick I found out last time.
It seems like the Pokémon GO app tracks how quickly you move the ball across the screen, not how fast you actually move the ball.
You can put the app into pop-up mode and just throw the ball like normal and it will absolutely soar.
If you aim for the top corner of the popped up screen and release a curve ball right there it will hit directly in the middle of a small excellent circle on her almost every single time.
Catching Lunala was an absolute pain for me at first, but after doing this I've been able to hit the smallest circle on her multiple different times.
If you have an Android phone, I would 100% recommend trying this.
It's a game changer.
TLDR: On Android, throw the ball in windowed/pop-up mode for far-away catches like Lunala. This tricks the tracking speed and makes the ball soar easily.
