Does the BMR calculator update automatically if I plug in a different activity level, or do I have to re-enter everything manually each time I tweak my routine?
@yldzk88q Hey Yıldız! Great question. Previously, you didn't have to re-enter everything, you just had to click the 'Calculate' button again—but you know what? You're totally right, that was an unnecessary extra click.
Because of your comment, I actually just pushed an update 5 minutes ago! It now auto-updates instantly in real-time as soon as you tweak your activity level or goals. Give the page a quick refresh and let me know how it feels! 🙌
Love the no sign-up approach. Does it save my data locally or do I lose my calculations every time I close the tab?
@reyhanorak2xlr Hey Reyhan! Thanks so much for the kind words!
To be completely honest, it didn't save locally before, but I absolutely loved your question and realized it's a must-have feature. So... I literally just coded and deployed local storage saving 5 minutes ago!
Now, all your stats will automatically save directly to your browser's local storage (no databases, complete privacy). You can close the tab, restart your computer, and your numbers will be exactly where you left them. Give the page a quick refresh and try it out! Let me know what you think! 🙌
Love the no sign-up approach and the clean look, it's exactly what I want in a quick fitness tool. One thing that would make it a daily driver for me is a saved history tab so I can track how my weight and macro targets shift over time.
@saniye0ike Hey Saniye ! Thank you so much for the feedback! You actually read my mind—I love the idea of tracking macro shifts over time without forcing sign-ups.
In fact, multiple people asked for this today, so I literally just coded and deployed a "History Log" feature 10 minutes ago! Now, when you calculate your macros, you'll see a "Save to History Log" button. It takes a snapshot of your weight and goals and saves it strictly to your browser's local storage (100% privacy, no DB).
Give the page a hard refresh and test it out! Let me know if this is what you were imagining! 🙌
Love how clean this is, no sign-ups is a huge win. One thing that would make it stickier for me is a saved history log so I can see how my TDEE or macros change over time when my weight shifts.

The clean layout without any clutter feels really intentional. Love that you can jump straight into a macro calc without an account or popup getting in the way.
