Maybe you have tried to capture a golf swing or fast flying object with your mobile cam. I guess you sometimes missed that opportunity due to the (compared to your DSLR) slow camera.
Burst mode is an app that takes multiple shots and you can then choose which one’s you wanna save. Quite handy sometimes.
The app used to cost $2 but now it’s free (for a limited time?). A little app to try out during your weekend walk? (Btw, do you notice the slight optical illusion on the right pic?)
