Ad-Free Smartwatch Companion

Open-source companion app for Casio smartwatches, no ads or tracking

Problem

New Casio F-B100W smartwatches only have an official app full of ads and tracking, harming privacy and user experience. Many users want a clean, open-source alternative but lack development skills.

Solution

An open-source mobile app that reverse-engineers the Bluetooth protocol to replicate core official features (notifications, step count, settings) without ads or tracking. Supports community contributions and customization.

Users

Privacy-conscious smartwatch users, open-source enthusiasts, Casio fans

MVP

Connect and sync time; receive notifications; view step count; basic settings; open-source repo

Revenue

Donations or sponsorship, or paid custom features (e.g., watch face marketplace)

Why now

Growing privacy concerns around wearables and mature reverse-engineering tools; solo devs can quickly replicate protocols
