Architecture

How the products connect.

Architected with intention. Clear boundaries protect your personal privacy and keep each tool reliable.

Personal tracking stays yours

KFit stores your workouts, body composition and meals locally on-device. KFit Web accesses your data only if you explicitly choose to sign in for multi-device sync.

SQLite via Drift → Postgres Sync

Gym operations remain strictly separate

GymWorld is an independent business workspace for gym owners. It manages member rosters and dues, but has zero access to your personal meals or workout metrics.

Isolated Workspace Boundary

Realtime on-device voice companion

JARVIS connects directly to KFit through an Android Binder IPC bridge. Voice interactions execute with low latency and without cloud roundtrips for local logging.

Android Binder IPC Bridge
Core Values

Built on a few simple principles.

We built KFit because health tracking apps became subscription-heavy, bloated with ads, and unfaithful to Indian diets.

01

Local-first by default

Your health records live in a private SQLite database on your device. Logging meals, workouts, and hydration requires zero internet connection.

02

Transparent nutrition sources

Every calorie and macro resolves against curated Indian recipes and verified IFCT-2017 lab data. We do not invent numbers or guess based on word count.

03

Account optional

Open the app and start logging immediately. No account signup, phone number verification, or profile questionnaires required before you can track.

04

Core tracking without subscription

KFit core tracking is free with no subscription. Essential tracking features, macro resolution, and historical trends are never gated behind monthly paywalls.

Installation

How to install on Android.

KFit is distributed directly as an official signed APK. Sideloading gives you direct software access with zero intermediary store trackers.

Step 1

Download the APK

Tap the download button above or grab the release asset directly from GitHub Releases.

Step 2

Open Downloaded File

When download completes, tap the notification or open the APK from your browser or Files app.

Step 3

Allow Installation

Android will prompt to allow installations from your browser. Toggle permission to continue.

Step 4

Start Tracking

Open KFit and immediately begin logging meals and workouts. No account creation required.

Standard Android Security Prompt

Because KFit is installed directly without the Google Play Store, Android shows a standard warning about unknown sources. Every release is cryptographically signed and SHA-256 hashed. You can verify the checksum below.

Transparency

Cryptographic release verification.

Verify the integrity of every published APK. Independent cryptographic checksums guarantee that your download is untampered.

Engineering Philosophy

Crafted with care in Bangalore.

KFit started with a simple observation: modern fitness applications became overcrowded with ad carousels, opaque algorithms, and foreign food catalogs that fail to understand Indian eating habits.

We set out to build something different. A focused, local-first ecosystem that tracks real meals in authentic portions, keeps your private data on your physical device, and never locks basic wellness tracking behind monthly paywalls.

Every layer — from the Android SQLite schema to the PWA synchronization engine and voice companion — is built with craft, honesty, and deep respect for user autonomy.
