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.

Menopause shouldn’t feel like a guessing game. Sage is the AI symptom tracker built for perimenopause, menopause, and postmenopause. Log how you feel in 45 seconds, and let your data tell the story your body has been trying to share. Most days, the question isn’t “what am I feeling” — it’s “why is today worse than yesterday?” Sage answers that. After two weeks of check-ins, our pattern engine begins surfacing triggers you can actually act on: the second glass of wine, the 6-hour night, the week before your cycle finally went quiet. Whether you’re three years into hot flashes or just starting to wonder if “this is it,” Sage gives you a calm, private, evidence-aware place to track your transition. — WHAT YOU CAN TRACK (FREE, FOREVER) — • 35 menopause symptoms with intensity sliders: hot flashes, night sweats, brain fog, mood swings, fatigue, joint pain, sleep disruption, anxiety, irritability, heart palpitations, vaginal dryness, low libido, weight changes, headaches, and more • Sleep quality, caffeine, alcohol, exercise, and stress tags • Apple Health sync for Sleep Analysis and Heart Rate • Beautiful calendar view of your last 28 days — PREMIUM: WHERE THE AI EARNS ITS KEEP — • Pattern Insights — your personal correlations, in plain English Example: “On caffeine days, your hot flashes are 2.3x more intense” or “Nights under 6 hours of sleep drop your next-day mood by 40%.” • 7-Day Symptom Forecast See which symptoms are likely to flare in the week ahead, so you can move that big meeting, pre-stock the cooling spray, or simply give yourself permission to slow down. • Personalized Lifestyle Coaching Evidence-based, non-HRT strategies that match your actual patterns — not a generic top-10 list. — WHO SAGE IS FOR — Women in their 40s, 50s, and 60s navigating perimenopause, menopause, or postmenopause. If you’ve ever stared at a hot flash log on paper and thought, “there has to be a smarter way,” that was us building Sage. — PRIVACY YOU CAN ACTUALLY VERIFY — • All health data encrypted with AES-256 • Your data is never sold and never used to train AI models • Sign in with Apple — no email lists, no spam • Delete your account and every record at any time, in two taps (GDPR-compliant) Sage does not provide medical diagnosis. Our AI insights include guidance to consult a qualified healthcare professional for any clinical decisions. — PRICING — • Free forever: daily check-ins, 35 symptoms, calendar history, Apple Health sync • Premium Monthly: $12.99 / month • Premium Annual: $89.99 / year (≈ $7.50/month — save 42%) • 7-day free trial on the annual plan Subscriptions auto-renew unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your Apple ID settings. Any unused portion of a free trial is forfeited upon purchase.
