Free health apps for your workouts, water, and baby

Pick the part of your health you want to fix. One app per job, each doing it well — not one bloated app doing ten things badly. More health verticals coming.

Most health apps are quietly working against you

They lock the good stuff behind a day-one subscription, nag you with streaks, and quietly sell what they learn about you. I got tired of it — so I build the opposite: apps that are free to use, need no account, never sell your data, and actually help you, then get out of your way. All made by one person who uses them every day.

No catch. That's the whole pitch.

Apps built to help you, not use you

Actually helps you

Each app does one thing and is built to help you actually do it — show up, drink up, keep track. No endless feeds, no busywork, nothing designed to keep you hooked.

Free, with no traps

Free to use, no day-one paywall, no account to create. Premium is optional and mostly just removes the ads — and I never sell your data.

Made by one dev who uses them

No growth team, no dark patterns, no retention tricks. Just an indie developer building the health tools he wanted for himself.

One developer, building health apps that actually help

I'm Alex, a solo developer and a dad. I built these apps because I couldn't find simple, honest tools for my own health — everything was bloated, locked behind a subscription, or quietly harvesting my data.

So I build the opposite, one small app at a time: free to use, no account, and I never sell your data. Workouts, hydration and baby care today, with more areas of health on the way.

Plus 25 free health calculators

Water intake calculator, push-up test, calorie and BMI calculators and more — instant results, no sign-up, no email, in your language.
