Kilra is a symptom tracker for people living with a chronic condition. Log what you feel, log what you do, and Kilra shows you what the two have in common. WHAT IT DOES Symptom tracking Log a symptom in about thirty seconds. Forty symptoms, severity 1-10, triggers and notes. Every entry comes straight back as a read: how today compares with your usual, how many times this week, and when these tend to land. Habit and dose tracking Record routines, medication and sleep alongside your symptoms, so there is something to compare your days against. Learns your body Kilra compares your worse days with your better ones, factor by factor, and ranks what lines up. It shows the strength of each association and how confident it is. The record keeps getting sharper the longer you log. Doctor-ready reports Your whole history on one page, formatted for an appointment. Visits, labs, dose changes and everything you logged, in order. BUILT AROUND ONE DAILY HABIT Open it, tap a number, done. The home screen opens on what you have recorded rather than on a form. Nothing is withheld behind a countdown - your record starts working the first time you use it and improves every day after. PRIVATE BY DESIGN Your health data stays on your device. Analysis runs on your iPhone, not on a server. No account needed to start. HONEST ABOUT WHAT IT IS Kilra finds associations in your own data. It is a tracking tool, not a medical device, and it does not diagnose. It will tell you when it does not have enough data to say something, rather than guessing. Every number it shows you is one you can check. SUBSCRIPTION Kilra is a paid subscription with weekly, monthly and annual plans. The annual plan includes a 3-day free trial. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Terms of Use: https://symptly-privacy.vercel.app/#terms Privacy Policy: https://symptly-privacy.vercel.app

Is your shampoo hiding sulfates? Does "fragrance-free" really mean fragrance-free? SimplyScan reads the ingredient list for you and shows you, in seconds, what you're really putting on your skin and hair. HOW IT WORKS • Snap a photo of the ingredient list on any shampoo, soap, lotion or cosmetic with SimplyScan • The app analyses every ingredient and checks against published safety research. • Get a 0–100 safety score and a clear letter grade, A to F. WHAT THE APP CHECKS Parabens, sulfates, phthalates, formaldehyde releasers, undisclosed fragrance, chemical UV filters, PFAS and more. ONLY GOT THE FRONT OF THE PACK? If your photo shows the front instead of the ingredient list, SimplyScan can look the product up and show you its full ingredient list. KNOW YOUR INGREDIENTS Search any ingredient to see what it is and whether it's a concern, and learn how to read a label. HONEST BY DESIGN A product with no readable ingredient list gets "not enough information" — never a good score. Blurry photo? SimplyScan asks you to rescan instead of guessing. Health concerns, irritants and preference notes are labelled differently, so a silicone preference never masquerades as a health risk. YOUR SCAN HISTORY Every product you check is saved with its photo, score and grade. SIMPLYSCAN PRO *Scanning features requires a paid subscription. Subscription information and terms can be found within the app.* Payment is charged to your Apple ID account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Privacy: label photos are analysed securely in the cloud and are not stored. Your scan history stays on your device. SimplyScan is for information only and is not medical advice.

Verdict
The clearest difference is ads: Kilra at none against SimplyScan's shown. Kilra also leads on update cadence (weekly vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
