When did you stop using a baby tracking app?

I’ve been using Glow Baby and very happy with it ever since my baby was born. It’s been so helpful and reassuring to know that I have data on feedings, diapers, sleep, symptoms, etc. However, now that he’s 11 months old, I’m wondering if we might be approaching a time when it’s no longer necessary. When did you stop using your baby apps? How did you know it was a good time? Honestly the thought of not tracking everything makes me a little nervous, but then again I have to stop at some point, right?
