ClearCheck: Medication Safety

ClearCheck computes how long the FAA's rule of thumb says to wait after an over-the-counter medication — before it becomes a problem in the run-up area. It estimates a wait time from published dosing intervals; it does not decide whether you are fit to fly. HOW IT WORKS Scan a medication's barcode, photograph its Drug Facts label, or search by name. ClearCheck resolves the product to its ACTIVE INGREDIENTS — never the brand name alone, so combination products like nighttime cold formulas or "PM" pain relievers can't hide a sedating ingredient. You get a clear verdict: • RED — Do Not Fly While Using (sedating antihistamines, sleep aids, anything with an impairment warning) • YELLOW — Wait Required, with the computed wait time • UNKNOWN — Not Assessed. Most of the openFDA catalogue: an ingredient nobody has reviewed against FAA guidance. ClearCheck has no wait for it and says so, rather than showing you a green light it hasn't earned. • GREEN — No Wait Computed (e.g. plain ibuprofen or acetaminophen). A statement about the medication, not about you. Tap "I took this at [time]" to log a dose. ClearCheck computes and shows a "COMPUTED WAIT ENDS AT" timestamp with a live countdown, plus a notification when that wait has elapsed. THE MATH IS SHOWN, NOT HIDDEN ClearCheck applies the FAA's rule of thumb — wait 5 times the maximum labeled dosing interval — with known FAA-specific overrides where they exist (diphenhydramine: 60 hours). For multi-ingredient products, every ingredient is computed individually and the longest wait governs, with a full breakdown so you can verify the arithmetic yourself instead of trusting a black box. PLANNED FLIGHT MODE Enter a departure time and get the latest moment you could take a medication and still clear in time. OFFLINE BY DESIGN The medication database is bundled with the app — no signal required in a hangar or FBO. Sync when you have a connection to widen coverage. Dose logs are stored only on your device: no account, no cloud, no PHI on a server. Export your dose history as a PDF logbook anytime. ONE-TIME PURCHASE ClearCheck is unlocked with a single $9.99 purchase, billed through the App Store. No subscription, no renewal — buy once and it's yours. Try 10 free lookups first; see the in-app Terms of Use and Privacy Policy for details. WHAT THIS APP IS NOT ClearCheck is not medical or regulatory clearance, and it never claims to be. Every verdict links to an AME locator, the FAA's "Medications and Flying" brochure, and its OTC Medications for Pilots guide. Most importantly: if you're sick enough to need medication, the underlying condition — not just the drug — may be disqualifying under 14 CFR 61.53. ClearCheck says so, prominently, every time. Built for the cockpit: high-contrast dark theme, large tap targets, one-handed operation.
