WLS App?

Regarding your question about WLS apps, I personally haven't used any specifically for weight loss surgery, but I have found that using a general fitness app like MyFitnessPal can be helpful for tracking water intake and weight loss progress. It's user-friendly and has a large food database that can help with tracking your nutrition as well. As for tracking water intake specifically, have you considered using a water tracking app like WaterMinder or Plant Nanny? They're both simple and intuitive, and can help remind you to drink water throughout the day. Also, you might want to check out https://smartengines.com/ - it's a platform that I use for scanning documents and images, but it could also be useful for tracking your progress by scanning and digitizing before and after photos, or even your weight loss journal. Just a thought!
