Clinical Grade Precision

Built Specifically for Post-Surgical Healing

Eliminate disorganized paper notes, confusing medication schedules, and missed drain outputs during critical recovery windows.

Alternating Schedule Engine

Pairs primary and secondary analgesics (such as Acetaminophen and Ibuprofen) on interleaved timelines strictly according to your physician's prescription. Dynamic intervals calculate from the actual taken time to prevent stacking and accidental acetaminophen toxicity. Drain & Dose is an organizational logging utility and assumes no liability for medication administration—always follow your doctor's exact orders.

JP Drain Output & Removal Goal

Log Drain 1 through Drain 6 with fluid characteristics and AM/PM rolling 24-hour totals. Automatically evaluates the clinical benchmark of < 30 mL per drain over 24 hours for 2 consecutive completed days to share with your surgeon.

Doctor-Ready PDF Export & Printouts

Generate high-resolution clinical PDF reports and blank physical printouts directly on-device with zero cloud dependencies. Formatted with color-coded fluid logs, per-drain daily totals, and trend tables for your surgeon follow-up visits.

PRN Breakthrough Lockout Timers

Manage as-needed rescue opioids and anti-emetics strictly following your doctor's orders with active visual cooldown timers enforcing minimum safe dosing intervals before the next dose can be logged. Always consult your physician regarding dosage limits and pain management.

1-Tap Caregiver Plan Share

Handoff care plans and schedules to spouses, family, or nurses via secure .drainanddose files over AirDrop, Messages, or Files with 100% on-device import.

100% On-Device & Biometric Privacy

Medical privacy is sacred. Unlike other apps that upload sensitive health logs to remote cloud storage buckets, Drain & Dose is built with a zero-cloud, hardware-isolated architecture.

Zero Cloud Databases & Zero Storage Buckets

All medication dosages, drain logs, patient profiles, and surgical timestamps live strictly on your physical device in encrypted local databases. We operate zero remote storage buckets holding your medical records.

Biometric Hardware Protection

Gate access to your surgical recovery logs using your device's native Face ID, Touch ID, or PIN passcode. Handled exclusively by Apple iOS or Android secure hardware enclaves.

Zero Third-Party Trackers or Data Collectors

Zero advertising SDKs, zero data brokers, and zero behavioral telemetry. We never track, harvest, rent, or monetize your recovery journey.

AI Policy, Safety & Zero Fake Testimonials

Drain & Dose uses deterministic mathematical safety engines (no unverified generative AI medical diagnoses). We publish zero fake reviews or fabricated endorsements, with strict policies against self-harm.

Common Questions

Frequently Asked Questions

Everything you need to know about Drain & Dose, recovery management, and data sovereignty.

How does the drain removal readiness criteria work per drain?

Most surgeons evaluate surgical drain removal when each individual drain's 24-hour output drops below 30 mL (or a custom threshold set by your surgeon) for 2 consecutive completed days. Drain & Dose evaluates this criteria per drain and presents a green milestone badge on your dashboard when criteria are achieved.

Does any medical data get uploaded to server storage buckets?

No. Drain & Dose operates on a strict 100% on-device architecture. All logs, dosage history, and clinical notes are saved in encrypted storage on your physical smartphone. There are no remote storage buckets or cloud databases holding your health records.

How does alternating acetaminophen and ibuprofen scheduling work?

Surgeons frequently recommend alternating two non-opioid analgesics (such as Acetaminophen and Ibuprofen) every 3 to 4 hours. Drain & Dose dynamically interleaves both schedules and recalculates the staggered intervals based on when you actually log taking your dose, preventing accidental acetaminophen stacking and liver toxicity.

Can I print my clinical drain log or export a PDF for my doctor?

Yes! With one tap, you can generate a doctor-ready PDF report formatted with color-coded fluid logs, per-drain rolling totals, and trend tables. You can print directly to any AirDrop/Wi-Fi printer or share via email and electronic patient portals.

How is AI used in Drain & Dose?

AI software development tools were used during software engineering to assist human engineers in coding and testing the app. In the app itself, calculations (timings, milliliters, intervals) are 100% deterministic math—we do not use autonomous generative AI to produce medical diagnoses or alter prescribed treatment plans.

Can I hand off care to a spouse, family member, or caregiver?

Yes. You can export your patient profile and schedule into a 1-tap .drainanddose file. The caregiver can tap the file on their iOS or Android phone to import the entire care plan instantly via AirDrop, Messages, or Files without any central cloud account required.
