Digital irrigation timers vs mechanical

Is there any reason NOT to have a digital, app controlled irrigation timer?

I live in a tropical climate (South Florida) where regular watering is absolutely required. Me and all of my neighbors have these super old mechanical timers. My timer recently stopped working. Based on some brief research the most likely culprit is the timer motor.

So is there any reason I should just replace the timer motor vs swapping the timer completely for a digital option? Looking on amazon it seems like you can get a decent digital timer for under $100. The motor replacement will be about $20. So I guess aside from cost, why shouldn’t I swap to a digital option?

Thanks in advance - I’m definitely still a novice when it comes to lawn care.
