iPhone
Eidos is the nutrition plan that adapts to you, week after week.
No diary to fill in. No meal photos. No gram counting. Open the app, follow the plan, complete a 30-second morning check-in. Eidos reads your data and recalibrates the plan when needed — grounded in scientific evidence, not slogans.
THREE MOVES A DAY
* Follow. Each day shows meals, macros, and timing. Nothing to decide.
* Log. Weight and meal adherence in under a minute. For shape, not judgment.
* Observe. The system compares real trend and plan. When needed, it suggests a one-tap adjustment.
THE ADAPTIVE ENGINE
Eidos estimates your energy needs with validated formulas (Mifflin-St Jeor, PAL/TDEE), sets macros and calories for the selected program, and every 7 days compares weight, adherence, and planned calories from the previous seven days. Recalibration is proposed only when the trend is off track. Fully transparent, no magic.
FOUR PROGRAMS, ONE-TIME PAYMENT
* Moderate weight loss — 6-18 lb, 8-16 weeks.
* Significant weight loss — 18-44 lb, 16-32 weeks.
* Muscle gain — +4-11 lb, 12-16 weeks.
* Post-diet maintenance — stabilize weight, 12 weeks.
No subscriptions, no plans to cancel. Pay for the program, it is yours.
SHOPPING, ALREADY READY
Each plan generates a checkable shopping list, organized by grocery store section. Export it to PDF or iOS Reminders. Once done, then you cook.
SUPPORTED EATING PATTERNS
Mediterranean, vegetarian, vegan, pescatarian, low-carb, gluten-free. Allergies and unwanted foods handled during onboarding. Overlays for specific needs: digestion, anemia, hormonal irregularity.
EVIDENCE, NOT DOGMA
The Eidos engine is based on 2022-2026 meta-analyses and guidelines: LARN SINU 2024, 2025 national Mediterranean Diet guidelines, RCTs and umbrella reviews on weight loss, hypertrophy, plant-based patterns, and FODMAP. Every rule is traceable.
NO JUDGMENT. NO NOISE.
No streaks. No badges. No “great job!”. No emoji in app messages. Eidos tells you “on track” or “deviation” — that is all. For shape, not moral color.
PRIVACY
Sign in with Apple. Data on iCloud and European servers. No ad tracking, no data sales. Delete everything in one tap.
REQUIREMENTS
iPhone with iOS 17 or later. Languages: Italian, English.
