librefit

LibreFit is my hobby project that allows you to calculate your TDEE (Total Daily Energy Expenditure) based on your body metrics, create goals for weight loss or weight gain from that and encourages you to track your daily calorie intake. Based in your input, you will see easy to understand charts to keep on track with your goal - all that with privacy first in mind.

Introduction

LibreFit was created after tracking my caloric intake with some Excel and Google Sheets over a year. Out of boredom I decided to try a new stack I've never done anything productive with, I quite enjoyed the journey and thus this project was born.

Dependencies

• rust 1.77.2
• diesel 2.2.6
• tauro 2.0
• sqlite 3
• sveltekit 2.5.2
• skeleton 2.9.0

Tools

• Android Studio

Structure

The project follows the default tauri setup.

librefit
|- librefit-web
|- src-tauri

setup

Navigate to src-tauri/ and issue

cargo build

start

To start the development server, go to the project root and issue

cargo tauri dev

To start the android development server:

cargo tauri android dev

If you encounter an error like this:

java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "__floatunditf"

The linker path found in build.rs does not match.

• Navigate to $NDK_HOME.
• Search for the x86_64-android libclang file. If you followed the steps in the tauri docs, the path should look like this:

$NDK_HOME/toolchains/llvm/prebuild/<host>/<lib>/clang/<clang-version>/lib/<os>/libclang_rt.builtins-<guest>.a

• : Your system type, e.g. linux-x86_64
• : Either lib or lib64
• : Your OS type, e.g. linux
• : Guest system type, e.g. x86_64-android

export that as env variable, e.g. $LINKER

Force cargo to use that linker with RUSTFLAGS=-C link-arg=$LINKER

Example command (works on my machine (tm)):

RUSTFLAGS="-C link-arg=$NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/lib/clang/19/lib/linux/libclang_rt.builtins-x86_64-android.a" cargo tauri android dev
