# 4Meds — Simple Medication Tracker

> 4Meds is a fully offline, privacy-first medication tracking app for iPhone in five languages (English, German, French, Spanish, Italian), developed by Robert Poetzsch under the RobSpace brand.

## About

4Meds helps users track their daily medications and supplies, set reminders, log health data, and generate shareable PDF reports for doctor visits. It is designed for people who take multiple medications and want a simple, reliable, and private way to manage their adherence.

The app is available exclusively on the Apple App Store for iPhone (iOS 18.6+).

- Website: https://4meds.app.robspace.de/ (English, German, French, Spanish, Italian: ?lang=en|de|fr|es|it)
- Support: support@robspace.de
- Developer: Robert Poetzsch, Hofheim am Taunus, Germany

- Languages: English, German, French, Spanish and Italian (app since version 2.8, website including privacy policy and legal notice)

## Core Differentiator: Privacy by Architecture

4Meds makes zero network requests. This is not a toggle or setting — it is a fundamental architecture decision. The app contains no servers, no cloud sync, no analytics SDKs, no crash reporters, no advertising networks, no tracking pixels, and no account system. All data is stored exclusively on-device using Apple's SwiftData framework. Data only leaves the device when the user explicitly exports or shares it.

## Key Features

- Today Dashboard: Daily overview with progress ring, scheduled dose list, and one-tap taken/missed/skipped logging
- Medication Management: Recurring and on-demand medications, multiple dosage variants per medication, configurable dosage limits (per day/week/month); Meds tab rows show dose times, rhythm and a supply bar; archived medications fold away
- Supply Tracking (since 2.7): Optional supply per medication (or per variant) with pack size, amount per dose, unit and color; the amount on hand is calculated from logged doses and counts down with every dose; supply overview (amount left, run-out date, Refill, Ordered, History) and supply calendar (how long each supply lasts); "Stop Tracking" keeps the history, "Delete Supply and History" removes it
- Reorder Reminders (since 2.7): Per supply, "X days before it runs out" (scheduled medications only) or "when X are left"; repeats daily at the chosen time until marked Ordered or refilled; local notification
- Flexible Scheduling: Time-based schedules with interval mode (e.g. every 2nd day) or specific weekdays, optional end dates, pause and resume
- Local Push Notifications: Time-sensitive medication reminders that work through Focus modes, fully configurable per schedule
- Statistics & Adherence: Adherence rate, intake charts, missed dose patterns, on-demand usage, configurable time ranges (1 week to 3 months)
- Health Journal: Daily entries for mood (5-level scale), pain level (0-10), symptoms, side effects, and free-text notes
- Calendar Overview: Monthly view with color-coded progress rings per day, on-demand medication indicators (purple dot), and over-limit warnings (red exclamation)
- PDF Report Generation: Professional multi-page reports with patient info, adherence summary, daily adherence chart, medication tables, missed dose details; shareable via AirDrop, email, print, or Files
- Data Management: Full JSON export/import (including supplies), sample data, automatic weekly local backups (max 7 versions, also created manually via "Create Backup Now"), and delete-all with double confirmation
- Settings: Opened via the gear icon on the Today tab; sections Language (from 2.8), Notifications, Journal Reminder, Data Management, Local Backups, Community & Feedback, About, Impressum
- Five Languages (from version 2.8): English, German, French, Spanish and Italian; the app follows the iPhone's language, changeable via Settings > Apps > 4Meds > Language or the Language row in the app's settings
- Appearance: Always dark — Volcanic Obsidian theme with crimson red accents (no light mode)

## Privacy Policy Summary

4Meds does not collect, transmit, or store any personal data on external servers. The app makes zero network requests, includes no third-party SDKs, requires no account, and stores all data locally on-device. Local backups (JSON, the 7 most recent, automatic and manual together; automatic when Settings is opened and the last one is at least 7 days old) stay in the app's own storage on the device. "Delete All Data" does not delete the local backups; they can be deleted under "Manage Backups", and uninstalling the app removes everything. Links in "Community & Feedback" open github.com in the browser, the "Language" row and "Open System Settings" open the iOS Settings app; the app itself sends nothing. Full privacy policy (in all five languages): https://4meds.app.robspace.de/?lang=en#privacy-policy
