Most apps record a moment.
Grindline reads the whole day.

Finally, a workout app that isn’t a headache!
I’ve tried so many fitness apps, but most of them are either too cluttered or just plain boring. This one is genuinely fun to use! The interface is clean and not complicated at all, which is a huge relief when you’re already tired and just want to get your workout in. The workout generation feature is a game-changer—it saves me so much time planning and actually gives me great variety. Highly recommended!
