StackCal is the calorie tracker built for bulking, not cutting. Most nutrition apps assume you're trying to lose weight. StackCal flips the script. If you're trying to gain muscle, gain mass, or just stop under-eating, StackCal answers the one question that actually matters: "How much more do I need to eat today?" WHY STACKCAL - Bulk-first targets — Personalized BMR, TDEE, and surplus calculations based on your stats and goals. - 5–10 second logging — Snap a photo of your meal and let AI recognize the food and estimate calories. No barcode scanning, no database fumbling. - One dial for everything — Log weight and adjust portion sizes with the same analog dial. One gesture to learn. - Nothing hidden — Today's calories, what you ate, and your weight all live on the home screen. - Trend-based weight — See your moving average instead of fighting daily fluctuations. DESIGNED FOR CLARITY Three rules guide every screen: information is never hidden, the same gesture always means the same thing, and every tap produces a visible response. The result is an app you can use one-handed, post-workout, with sweaty fingers. PRIVACY FIRST - No account required. - Your meals, weight, and profile stay on your device. - Optional iCloud sync uses your private CloudKit container — we never see your data. - No ads. No IDFA. No tracking pixels. SUBSCRIPTION A free tier covers core logging. The subscription unlocks photo-based food recognition and advanced trend analysis. Cancel anytime in iOS Settings. Built for lifters who eat to grow. TERMS OF USE Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
