GlaShield is a free, senior-friendly glaucoma app that brings eye drop reminders, eye pressure (IOP) tracking and medical visit records together in one simple place. Living with glaucoma means daily eye drops and regular check-ups. GlaShield helps you stay on schedule, keeps your eye pressure and visit history easy to read, and takes some of the everyday effort out of managing your care. ■ EYE DROP REMINDERS THAT HELP YOU STAY ON TRACK • Daily reminders at the times you choose, for multiple eye drops and multiple doses a day • Tap the notification to open the recording screen right away • Even if you hide eye drop names in notifications, they show the scheduled time so you know which one it is • If you haven't recorded a dose, GlaShield reminds you once more 30 minutes later (set per alarm) • Choose from five notification sounds ■ TODAY'S EYE DROPS AT A GLANCE • Record each dose with one tap from today's list, and undo it if you tapped by mistake • Once the next dose time of the same eye drop has passed, the earlier dose is marked "skip it" to prevent a double dose. If you did take it, record it with "I had taken it" • A 30-day view shows how many days you used each eye drop • Quickly record eye drops that don't have an alarm • Add and change your eye drops and alarms from the same screen ■ VISIT RECORDS WITH AN EYE PRESSURE CHART • Record the clinic, right and left eye pressure, whether you had a visual field test or an OCT / fundus photo, your next visit date and notes • See your eye pressure trend on a chart, and set the target pressure your doctor gave you right below it to draw it as a line • Your next visit date is shown above your visit records (and on the Eye Drop Records tab from 7 days before), with reminders the day before and on the day ■ KEEP YOUR RECORDS SAFE • Save a backup file and restore it when you switch phones ■ EASY TO SEE, EASY TO USE • Choose Standard, Large or Extra large text (on top of your device's text size setting) • Dark mode: choose Match device, Light or Dark • Works with VoiceOver and TalkBack PERFECT FOR: • People with glaucoma who want help managing daily eye drops • Anyone who sometimes forgets their eye drops and wants a reminder • Patients who want to track eye pressure and make the most of ophthalmology visits • People who like to review their eye drop routine together with family • Anyone looking for a simple health app with large, easy-to-read text WHY GLASHIELD? 1. SENIOR-FRIENDLY DESIGN Large text and clear buttons make GlaShield easy to use, even if you're new to smartphones. 2. SIMPLICITY THAT KEEPS YOU GOING Just three tabs: Eye Drop Records, Visit Records and Settings. Open the app, tap a few times, and your record is saved. Daily care should be effortless. 3. YOUR RECORDS STAY ON YOUR PHONE Your eye drop, visit and eye pressure records are stored on your phone, and the app never sends them to an external server. No account needed. GlaShield shows a small ad at the bottom of the screen so it can stay free. You can remove ads with a one-time purchase at the top of Settings. Glaucoma care is a long journey. Take it at your own pace — GlaShield is with you every step of the way. Disclaimer: This app is not a medical device. It is a personal record-keeping tool and is not a substitute for professional medical advice, diagnosis or treatment. Always consult your doctor before changing how often you use your eye drops or switching medications, and about any medical condition.
