Zone2Lift
A coach's dream app.
Live Zone 2 on your Apple Watch. Your zone on your wrist, your plan on your iPhone.
An iPhone + Apple Watch app that puts each client's Zone 2 cardio, training, macros, sleep, blood pressure, glucose, body composition and bloodwork in one place, so lifters, competitors and their coaches can see the plan next to what actually happened.
Compatibility: requires iOS 17 and watchOS 10. The AI coach needs iOS 26 or later. Live zones need iOS 27.
Coaching data lives in too many places.
A serious lifter's week is spread across a watch, a sleep ring, a BP cuff, a food log, a scale, a lab portal and a training spreadsheet. The coach ends up rebuilding the picture from screenshots, DMs and PDFs, one client at a time.
Cardio
Heart rate and minutes on the watch, rarely matched to the cardio the coach prescribed.
Nutrition
Macros in MyFitnessPal, MacroFactor, Cronometer or Lose It!, sent over as screenshots.
Recovery
Sleep in Oura or Apple Health. Blood pressure on an Omron cuff or a sticky note.
Body comp
DEXA, InBody and smart-scale readings in different apps, units and formats.
Bloodwork
Lab PDFs and phone photos of results, with no simple trend across draws.
Training
Programs in a spreadsheet; the actual sets, reps and load reported later, if at all.
Check-ins
Weekly updates arrive in different formats from every client on the roster.
Follow-up
Retests and reminders tracked by memory or in a separate calendar.
The result: more time chasing screenshots, less time coaching. Zone2Lift is designed to bring those sources together per client, with the coach's own targets alongside.
One place per client. Plan next to actual.
Zone2Lift pulls what the athlete already tracks through Apple Health and manual entry, then shows it to the athlete and, with consent, to the coach.

Live Zone 2 on Apple Watch.
Zone2Lift is an iPhone + Apple Watch app. Start a session and your current zone is on your wrist; the iPhone keeps the detail.
Zone2Lift shows the live heart-rate zone on the wrist and tracks weekly Zone 2 minutes against a goal.
- Zones from your own resting heart rateZones start from the Karvonen (heart-rate reserve) method, then apply a small, capped adjustment (an estimate, not a measurement).
- Live Watch zonesSee your current zone and heart rate on the Apple Watch while you train, with the same zone on the iPhone.
- Weekly Zone 2 minutesA weekly ring shows your minutes in Zone 2 against a goal. Widgets are planned.
- Apple Watch cardio fitness estimateThe cardio fitness value is shown as the Apple Watch cardio fitness estimate from Health, not a Zone2Lift measurement.
- Original robot mascotA green robot that rests when you rest and runs faster as the zone rises.
Body, recovery and fuel in one view.
Blood pressure
Omron readings via Apple Health, plus manual entry. Shown against the range the user or coach set.
Sleep
Sleep from Apple Health, for example Apple Watch or Oura.
Body composition
DEXA, InBody and smart-scale entries: weight, body-fat %, lean and fat mass.
Nutrition
MyFitnessPal, MacroFactor, Cronometer and Lose It! via Apple Health.
TDEE, two ways
Compares an Apple Watch energy estimate with an intake-vs-weight-trend estimate.
Water
Water intake tracked toward a daily target.
Bloodwork and hormones, tracked over time.
- MarkersLipids, ApoB, HCT, hemoglobin, RBC and custom markers, each with ranges set by the user or coach.
- On-device lab import, with reviewLab import is designed to run entirely on your device (text recognition, PDF, CSV). Nothing is uploaded. Every value is reviewed before saving.
- Trends & retest remindersTrend lines per marker and reminders on intervals the user or coach chooses.
- Hormones and custom markersHormones and other custom markers you import or type in, with units converted and detection limits kept as reported.
- Your ranges onlyRanges are only ones the user or coach sets. They stay empty until someone sets them. Coach sharing for hormones is off by default; the user decides whether to turn it on.
Private AI coach
Weekly summary and “What changed?” cards that describe changes in your data. It uses Apple's on-device Foundation Models, runs on your device, and is off by default. Needs iOS 26 or later.
Robot mascot
An original green robot that rests when you rest and runs faster as the zone rises, on iPhone and Apple Watch.
Glucose next to meals and training.
Zone2Lift shows glucose readings alongside the day's meals and workouts, and compares them with a range the user or coach sets. Not a medical device. Readings are shown against a range you or your coach set.
- CGM via Apple HealthReadings from Dexcom, Libre or Stelo sensors that write to Apple Health.
- Manual entryFingerstick readings with meal tags: fasting, pre-meal, post-meal.
- Daily curve, time in range, average & variabilityOne line per day with meal and workout marks. Share of readings inside the range the user or coach set. Average, standard deviation and coefficient of variation.
- Coach roster columnTime in range per client, for clients who choose to share glucose.
Built for a full roster.
- Multi-client rosterDesigned for 25+ clients, with search, tags (off-season, prep, peak) and a glucose column. Sample clients in v0.
- “Needs attention” sortBrings up clients outside the ranges the coach set. A sort, not a judgment.
- Invites with consent (coming later)Clients accept an invite and choose what to share, category by category.
- Permissions + audit log (coming later)Per-category access, with a log of what was shared and when.
- One-tap reports (coming later)A client PDF report and a weekly multi-client digest.
- Macro targets by phaseOff-season / prep / peak targets with adherence shown per client.
One dashboard: what was planned, what happened.
The coach sets the phase, the lifting plan and the cardio prescription. The client accepts it. Zone2Lift compares the plan with what was logged and shows adherence against the floor and tolerance the coach set. Sample clients in v0.
Lifting programs
Sets, reps, load and volume: planned vs logged, with missed or modified sessions.
Macros by phase
Off-season / prep / peak targets, training- and rest-day, with a ±% tolerance.
Cardio minutes
Prescribed Zone 2 minutes vs minutes tracked on the Watch.
Export
CSV and a PDF analysis report for check-ins.
Works fully without a coach.
Not every lifter has a coach. In solo mode, Zone2Lift is the whole toolkit: the user sets their own targets and gets the same Plan vs Actual view a coach would see.
Your own macro phases
Set off-season, prep or peak targets, training- and rest-day, with your own tolerance.
Your own lifting plan
Sets, reps, load and volume, compared against what you logged.
Your own ranges
Set ranges for BP, glucose, bloodwork and hormones, or leave them empty.
Same Plan vs Actual
Training, macros and Zone 2 minutes, side by side, every week.
Start solo
Build your history
Add a coach later
