I’ve been testing MARLÖ for a few weeks now, and it’s clear this app fills a specific niche. If you’re someone who struggles with dry eyes and uses Alcon’s Systane® Hydration Multi-Dose drops, MARLÖ helps create structure around your treatment. The reminder feature is straightforward—you set times for drop usage, and it pings you with a notification. No more guessing whether you’ve used your drops today. What I appreciate is the symptom tracker. You can rate dryness, irritation, or blurriness daily, and over time it generates a simple graph so you (or your eye doctor) can spot trends. It’s not overly complex—just enough to feel useful without becoming a chore. I will say the app is pretty tied to Alcon’s product ecosystem, so if you’re using another brand, this might not be the best fit. Also, a few users mentioned occasional sync issues, but it’s been smooth for me. Overall, it does what it promises: helps manage dry eye treatment more systematically. Not flashy, but practical for the right user.
