"Finally an app that doesn't coddle you. I've lost 8kg in 10 weeks just by actually staring at my numbers every day. Olie told me my Wednesday dinners were killing my deficit — she was right."
"I've tried every calorie app out there. Caldef is the only one that actually tells me why I'm not losing weight, not just what I ate. The AI coach is insane for a free app."
"The deficit tracker and calorie ring make everything so visual. I can see within 2 seconds whether my day is on track. Down 5kg, streak is at 34 days. Don't break the chain."
