## What is Masir?

Masir builds your running plan from the runs you actually do, not from a questionnaire. Then it reorganizes the plan when your week doesn't go as planned.

A PLAN BUILT ON YOUR REAL RUNS
• Masir reads up to 12 months of running history in Apple Health (read-only). Runs recorded by an Apple Watch, iPhone, Garmin, COROS or Polar count as soon as they write to Apple Health.
• No history yet? Log runs manually or record them with the iPhone's GPS.
• Training paces come from your current fitness, using Jack Daniels' VDOT formulas, adjusted for heat and humidity.

MISSED A RUN? YOUR PLAN ADAPTS
• Missed session, tiredness, illness, injury or vacation: the plan reorganizes itself and explains what changed.
• No backlog to catch up on: sessions in a break are removed, then you return at reduced volume.
• Training load builds in steps, so you don't do too much, too soon.

PLANS FOR EVERY GOAL
• Start running: 8-week walk-run program, free.
• 5K, 10K, half marathon and marathon, with or without a race date or target time.
• Improve your pace, come back after a break, or build general fitness.

EVERY SESSION, BLOCK BY BLOCK
• Each block with its pace and duration, and the purpose of the session.
• Live run with iPhone GPS: distance, time, pace and route on the map. No watch needed.

TRACK YOUR PROGRESS
• Fitness index out of 100, weekly volume and personal records.
• Fitness test: 12 minutes, 2 km or 5 km.
• Badges, "next session" widget, reminders, calendar export and a shareable run card.
• Miles or kilometers, Fahrenheit or Celsius.

PRIVATE BY DESIGN
No account. No ads. No trackers. No server: your data stays on your iPhone.

## Version history (last 5 releases)

### 1.3.3 — 2026-10-25

Fix: the "Missed session" card no longer appears for a session that is locked without a subscription.

### 1.3.2 — 2026-10-18

• Offer codes: a new "I have a code" button on the Masir Plus screen. With a code, your profile shows how long your free access lasts, and Masir reminds you a week before it ends.
• The reminder before your free trial ends now shows for everyone.
• Clearer privacy text and permission prompts.
• Translation fixes.

### 1.3.1 — 2026-10-15

Fixes and polish after 1.3.

• Your first week starts from what you already run, even without history in Apple Health
• If you don't run yet, the app suggests the free 8-week program before a 5K, 10K, half or marathon plan
• The plan preview shows your rest days and easier weeks
• Permission prompts now appear in your iPhone's language
• Privacy: Apple's weather service (WeatherKit) is now named clearly

### 1.3 — 2026-10-14

Training plans reworked from the ground up, checked against the reference methods.

• Marathon: a three-week taper, with the longest run three weeks before race day
• A race week scaled to your level, with a short race-pace reminder
• Intervals better dosed against your weekly volume
• Beginners: running without walking now comes in steps, from 20 to 30 minutes
• Low mileage: a gentler start, with no hard session in the first month
• No reference time? Your paces start from the one you already run
• GPS tracking: the distance at the start of a run is more accurate
• See your plan before subscribing: first week in detail, then what comes next, phase by phase
• Redesigned Masir Plus screen
• “Delete my profile” opens its confirmation again
• Send your workout to your Apple Watch: blocks and paces in the Workout app

### 1.2 — 2026-10-13

Masir has a new color: a deep green, a new icon and cleaner screens.

• Fitness index out of 100, with your progress month by month
• Clearer plan: your sessions week by week and the phase you are in
• Clearer sessions: each block with its pace and its time
• Simpler fitness test: 12 min, 2 km or 5 km
• Live run: distance front and center, heart rate and calories always visible
• Reworked dark mode
• Temperatures in Fahrenheit
