I’m a solo software developer, and I’m also a serious lifter. For years, I used popular workout apps like Hevy and Strong to log my progressive overload. But over the last couple of years, the fitness app space has gotten incredibly toxic.

It felt like every time I opened my app, another basic feature was stripped away and locked behind a $10/month paywall. Then came the mandatory cloud accounts, the tracking pixels, and the social feeds. I don’t want a social media network in the middle of a gym session. I just want to log my heavy sets and put my phone back down.

The breaking point for me was realizing that if I ever stopped paying my monthly subscription "rent," years of my personal biometric and training history would be held hostage behind a paywall. You do the work on the gym floor. You lift the weight. You should own your data. Period.

Out of sheer frustration, I decided to build the antidote. It's an Android app called Fit Log X.

The Solo Dev Reality Check: I won't lie—building this entirely by myself has been exhausting. I spent the last month managing a closed beta with 30+ testers, trying to fix obscure device crashes, refining the local database, and translating the app into multiple languages late at night after my day job. There were times I wanted to throw my laptop out the window because a volume chart wouldn't render right on older Android versions.

But hearing early testers say, "Thank you for not making me create an account," kept me moving. Today, I finally pushed it into Open Testing.

The Philosophy Behind Fit Log X:

• Always Offline-First: Every single rep, set, and body metric stays entirely on your phone's local storage. If you train in a basement gym with zero cell service, it works flawlessly.
• 100% Free & No Ads: No hidden paywalls, no premium tiers, no account registration screens. All analytics, routing features, and trend charts are unlocked from day one.
• Zero Friction: High-contrast, minimalist UI built for sweaty hands mid-workout. No clutter, no social feeds.

Why I'm posting here: I built this because I genuinely believe data sovereignty matters, even for something as simple as a gym log.

If you are a lifter, a privacy advocate, or just someone experiencing subscription fatigue, I would love for you to try it out and tear it apart. I need brutal feedback on the UX and the local performance metrics.
