CAPABILITIES
What the app actually does
Capabilities that ship today, from AI-generated programs and document import to metabolic targets, widgets and Apple Health sync.
Smart Document Import
Import your trainer's workout plan from PDF, DOCX, or up to 10 images. Workout plans are parsed on-device, auto-matched against our 2,400+ exercise database, and converted into a fully trackable template. Then export PDF reports and send them back to your trainer.
Cycle-Adaptive Training
Log symptoms daily and Zealo tracks where you are in your cycle. You get phase-aware guidance: iron emphasis during menstruation, hydration reminders, and food suggestions matched to the phase. Your calorie and macro targets deliberately stay fixed: the evidence does not support changing them by phase.
Zealo AI
An in-app coach you can ask about your own training. Photograph a meal and it estimates calories and macros against the day's targets, always with a confidence label attached, so you know when to trust the number.
Coaching and records
- Zealo AI
- An in-app coach you can ask about your own training. Photograph a meal and it estimates calories and macros against the day's targets, always with a confidence label attached. It reads your logged volume, adherence and goals, and flags it when your active plan works against the goal you set.
- Record board
- All-time bests across weight, reps and time, each with the date it was set and the gain over your previous best. Calculated estimates stay marked as estimates. The section is free; the full all-time board is part of premium.
Training
- 2,400+ exercise library
- The largest built-in database of 8 categories (weightlifting, yoga, calisthenics, HIIT, CrossFit, powerlifting, bodyweight, cardio) with video demos, pro tips, common mistakes, and variations for every exercise.
- Live workout tracking
- Active session timer with real-time set logging. Supersets, drop sets, giant sets. RPE tracking, auto-rest timers, and live volume/calorie calculation as you train.
- Live Activities
- A running workout appears on your Lock Screen and in the Dynamic Island, showing the current exercise, the one coming next, sets completed and session volume. The timer switches to a rest countdown between sets, and rest can be skipped without opening the app.
- Workout detail view
- Every workout broken down into structured sections: warm-up, main exercises, and cooldown. Each exercise shows sets, reps, target weight, rest time, intensity level, and muscle groups hit. Tap any exercise for pro tips and form notes.
- Smart training splits
- Deterministic split engine: PPL only at 6x/week, Upper/Lower at 4x, Full Body for beginners. Rest days placed intelligently. AI fills exercises within the structure, not the other way around.
Body and nutrition
- Metabolic engine
- BMR, RMR, TDEE, body fat percentage, fat-free mass, BMI and hydration targets in one dashboard. When fat-free mass is known, resting energy uses the Modified Mifflin-St Jeor equation validated against clinical DEXA reference.
- Precision nutrition
- AI-calculated daily macros for protein, carbs and fats, sized for your body and goal. Activity-adjusted TDEE with goal-specific calorie offsets (deficit, surplus, or maintenance).
- Apple Health sync
- Deep HealthKit integration that syncs heart rate, steps, active calories, body composition, and menstrual cycle data. Your complete fitness picture, unified in one app.
- Transformation photos
- Side-by-side progress photo comparisons with a built-in workout camera. Capture your transformation over weeks and months with timestamped, organized photo timelines.
Your data
- Trainer-ready PDF reports
- Generate comprehensive workout cycle reports as shareable PDFs covering body metrics, volume trends and muscle group distribution. Send them directly to your trainer for review and feedback.
- iCloud backup and sync
- All your workout history, plans, body metrics, and progress data backed up to iCloud. Switch devices seamlessly and your data follows you everywhere.
- Home and lock screen widgets
- Glanceable iOS widgets for your home screen and lock screen, showing today's workout at a glance, training streak, weekly volume, next scheduled session, and progress rings. Your fitness data without even opening the app.
How It Works
One platform. Every system connected.
The engines behind Zealo, from generating your program to what shows on your Lock Screen mid-set.
Swipe through all 9 systems.
- AI Program Generation01/09
Describe your goal. Get a full program instantly.
Tell Zealo your goal, training split, equipment access, and available days. The AI engine generates a complete plan with structured sessions, progressive overload, and nutrition context in seconds.
- Goal-based program generation with AI
- Handles split, equipment, and schedule constraints
- Builds structured sessions ready to execute
- Includes progression logic from week to week
- Zealo AI02/09
A coach that tells you how sure it is.
Ask about your own training in plain language. Photograph a meal and Zealo estimates its calories and macros against the day's targets, labelled high, medium or low confidence, so you know when to trust the number. It reads your logged volume, adherence and goals, and says so when your plan and your goal disagree.
- Ask questions against your own logged training
- Calorie and macro estimates from a photo of a meal
- Every estimate carries an explicit confidence label
- Flags a plan that contradicts your stated goal
- Smart Import03/09
Your trainer's plan. Now fully trackable.
Import a trainer-written program from PDF, DOCX, or up to 10 images. Workout plans are parsed on-device, auto-matched against our 2,400+ exercise database, and converted into a structured template you can execute instantly.
- PDF, DOCX, and image-based plan import pipeline
- Workout plans parsed on-device, with no manual retyping
- Auto-match against 2,400+ exercise database
- Converted to a fully trackable workout template
- Cycle-Adaptive04/09
Phase-aware guidance, without invented numbers.
Daily symptom logging builds a picture of your cycle across months. Zealo surfaces phase-appropriate guidance (iron emphasis during menstruation, hydration prompts, food suggestions) while your calorie and macro targets stay deliberately fixed. Systematic phase-based calorie modulation was removed because the evidence does not support it.
- Phase prediction from your logged cycle and symptoms
- Iron emphasis during menstruation
- Hydration prompts for ovulatory and luteal phases
- Calorie and macro targets held constant by design
Record Board05/09Every lift's best, on one board.
A record board across weight, reps and time. Each entry carries the date it was set and the gain over your previous best, with the plate breakdown for the working weight. Calculated estimates stay labelled as estimates rather than being mixed in with lifts you actually hit.
- All-time bests by weight, reps and time
- Gain over your previous best on every entry
- Plate breakdown for the working weight
- Estimated records labelled, never shown as set
PDF Reports06/09Train. Report. Share with your trainer.
Zealo closes the coaching loop: trainer creates the plan, you import and execute, then export a professional progress PDF with volume, metrics, and muscle distribution to send back for review.
- Automated trainer feedback reporting workflow
- Cycle volume and progress trend summaries
- Muscle group distribution breakdown
- Share-ready export in one tap
iCloud Backup07/09Your data. Always with you.
Workout history, progress photos, body metrics, and cycle data are automatically synced through iCloud with Apple ID continuity, so there are no extra accounts and no password overhead.
- Automatic iCloud backup and restore
- Seamless transfer across Apple devices
- No separate account creation required
- History, photos, and cycle data included
Live Activities08/09Your session, on the Lock Screen.
Start a workout and it runs on your Lock Screen and in the Dynamic Island. You see the current exercise, the one coming next, sets completed and session volume, with a timer that switches to a rest countdown between sets. Rest can be skipped without unlocking the phone.
- Live on the Lock Screen and in the Dynamic Island
- Current exercise and the one coming next

BUILT DIFFERENT
"A solo-built iOS app that shipped to the App Store with AI workout generation, cycle-adaptive training, and a 2,400-exercise database, before most teams ship v1."
Built by Manikanta Sirumalla, graduate student at UMBC. Designed, developed, and shipped solo.
