+# Android App
+
+Native Android app using Kotlin and Jetpack Compose that connects to the same TotalRecall API.
+
+## Requirements
+
+- Android Studio Hedgehog or newer
+- Android SDK 34
+- Kotlin 1.9+
+- Java 17
+
+## Building
+
+1. Open Android Studio
+2. File > Open > select the `android` folder
+3. Wait for Gradle sync to complete
+4. Build > Build APK
+
+Or from command line:
+
+```bash
+cd android
+./gradlew assembleDebug
+```
+
+The APK will be at: `app/build/outputs/apk/debug/app-debug.apk`
+
+## Configuration
+
+By default, the app connects to `http://10.0.2.2:3000/api/v1/` (localhost for Android emulator).
+
+To change the API URL, edit `app/build.gradle.kts`:
+
+```kotlin
+buildConfigField("String", "API_BASE_URL", "\"http://your-server:3000/api/v1/\"")
+```
+
+## Features
+
+- User registration and login
+- Create text entries
+- Voice memos
+- Health check-ins
+- View history by day
+- Generate AI journal
+- Configure AI provider (OpenAI, Anthropic, Ollama, LM Studio)
+

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/812c56a2fbbd51caf1865e37dbfb8e169137ab13/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
