OLTRA · iPhone and Apple Watch · Beta

Run further. Rest smarter.

Plans from 5K to 100K that know when to push and when to hold back. Each morning OLTRA reads your recovery, says it in one word and fills the screen with that colour. Then it builds the run, paces you through it in your ears, and adjusts the weeks ahead.

Coming soon to iPhone and Apple Watch

01 · The forecast

One word each morning.

OLTRA reads your heart rate variability, resting heart rate, sleep and training load against your own baseline. The colour tells you the day before you read a word.

The word comes from rules on your own readings, worked out on your iPhone. Every change it suggests is an offer, and every offer has undo.

Recovery is within your normal band

Clear.

Run the forecast as written. The day’s session and its paces, with your readings as chips under the word.

Tap Why? for the full reading.

The OLTRA app on iPhone: CLEAR on cobalt. Recovery is at your baseline; run the forecast as written. Chips for HRV 54, resting heart rate 48, sleep 7 h 24 and load 1.2 times, then today's session: rest, with tomorrow's 4.4 km easy run and hill sprints next.

Conditions are in your favour

Tailwind.

It says why in your own numbers. On a training day, OLTRA offers a harder session, with what was planned and what’s offered side by side.

Nothing changes unless you say so. It’s never offered in taper, race week or when you’re unwell.

The OLTRA app on iPhone: TAILWIND on lime: HRV 62 against your usual 51, resting heart rate 46, three below normal, slept 8 h 10, with the matching chips and today's session underneath.
Tailwind · Beta · sample data

One reading well off, or a short night

Gusty.

A little under par: a very short night, one reading well outside your usual, or a check-in that says you’re wrecked or carrying a niggle.

OLTRA offers an easier or shorter session. Take it, or run the forecast as written.

The OLTRA app on iPhone: GUSTY on amber: you slept 2 h 36 m last night, with chips for HRV, resting heart rate, sleep and load, and today's session underneath.
Gusty · Beta · sample data

Illness, injury, or strongly suppressed recovery

Storm warning.

The revised forecast is ready and says what would change. One tap makes it, and undo takes it back. If you feel fine, keep the forecast instead.

Red is rare on purpose: if hard days glowed red, you’d stop noticing. OLTRA is not a medical device. If symptoms get worse, talk to a doctor.

The OLTRA app on iPhone: STORM WARNING on red: two independent signals are outside your baseline. Below it, the revised forecast — tomorrow's run eases to recovery pace — with a Revise the forecast button and Log how I feel tomorrow.

Rain is your call.

OLTRA forecasts the weather inside.

02 · The run

Read it at arm’s length.

Pace now, big enough to read mid-stride. Under it, a line with your target in the middle and you as the dot, then the distance left in the rep. On the Watch, the whole face turns the colour of your effort zone.

And you don’t have to look.

OLTRA talks you through the session: when a rep starts and ends, when you drift off target, and when to ease back. It works from your iPhone alone; an Apple Watch adds heart rate.

“Ease back a touch — you’re a bit quick. Target 4:50, you’re at 4:41.”

03 · Apple Watch

The pace line.

One line on your wrist. The target is the centre tick and you’re the dot: left is behind, right is ahead. Underneath, how far off target you are, in seconds per km.

During a rep
The whole face is the zone colour, with pace, the pace line and the target.
During recovery
Calm cobalt with a countdown ring, how the last rep went, and the next rep spelled out.
Steady runs
You against a runner holding your goal pace, the gap in metres, and a projected finish.
How the Watch works, page by page
OLTRA on Apple Watch: an interval rep on a zone 4 orange face. Rep 3 of 4, 3.24 km, pace 5:22 per km, 34 seconds per km behind a 4:48 target, shown on the pace line.
Interval rep · test build
OLTRA on Apple Watch: recovery between reps on cobalt, a lime ring counting down 1:41, rep 2 on pace, next rep 3 of 4, 1 km at 4:48 per km.

04 · Race day

Pick your time. Then race it.

The day before, set the time you’re going for. OLTRA turns it into a pace, and on the day your Watch tells you how far ahead or behind that time you are.

The OLTRA app on iPhone: the race time sheet for City Half Marathon: a target of 1:50:00, which is 5:13 per km over 21.1 km, set on hour, minute and second wheels. Below it, a Fuel row with reminders at 0:30, 0:55, 1:20 and 1:40, then Race to 1:50:00 and No target, run by feel.
Race time · Beta · sample race
The OLTRA app on iPhone: the Fuel sheet: reminders at 0:30, 1:00 and 1:30 into the race, an Add a reminder button, a note on how the Watch taps and speaks, and Save 3 reminders.
Fuel reminders · Beta · sample race
Race time
Hours, minutes and seconds, with the pace it means beside it. Or skip the target and run by feel. Feeling good mid-race? Change it in Run settings.
Fuel
Set when to take a gel or a drink, as time into the race. At each one your Watch taps your wrist, shows FUEL and says “Time to fuel” through your headphones.
Pauses
Fuel times are running time, so stopping at an aid station holds them back.
Your race
Pick it from OLTRA’s race list. Find a race.

05 · The bigger picture

Weather is today. Climate is the block.

A plan from 5K to 100K, or for HYROX, that adapts to the runs you actually do. Outlook lays out the weeks ahead; the weather report tells you how today went.

The OLTRA app on iPhone: Outlook, week 1 of a half marathon plan in the base phase: one row per day with a weather icon — an 8.1 km tempo 3-2-1 on Monday, easy runs with hill sprints, rest days, a 96 minute long run on Saturday and a recovery run on Sunday, each with its pace.
Outlook · Beta · sample plan
The OLTRA app on iPhone: Your HYROX plan: Auckland HYROX on 5 February 2027, 15 weeks at 4 runs a week, a phase bar from building the engine through sharpening and taper to race week, starting week 31.6 km, peak week 50 km, longest run 16.5 km, emphasis on VO2max intervals.
HYROX plan · Beta · sample race
The OLTRA app on iPhone: the weather report for a past run: a map with the route in lime, Central Park Tempo Run, 10.02 km in 53:27 at 5:20 per km, 104 m of climbing, average heart rate 165, and an Upload to Strava button.

Outlook
The weeks ahead and their phases, one row per run. Move a session and OLTRA keeps your change.
Climate

Race day
Plans for 5K, 10K, 15K, half marathon, marathon, 50K, 100K and the running for HYROX. For a HYROX, give it the date and it trains the 8 × 1 km between the stations. Races and time trials retarget your paces. Find a race.

Share the run, not a screenshot.

Cards sized for Stories, posts or squares: your route, your figures, or your own photo behind the distance. They’re not in the beta yet.

07 · Questions

Before you ask.

What do I need?

An iPhone. It records with GPS and talks you through the session on its own. An Apple Watch is optional: it adds heart rate during the run, and the session on your wrist. For the forecast, OLTRA needs permission to read your recovery data from Apple Health.

What can I train for?

Plans for 5K, 10K, 15K, half marathon, marathon, 50K, 100K and the running for HYROX. Pick a race or a date and OLTRA plans a block that suits the distance. For a HYROX, give OLTRA the date and it trains the running: 8 × 1 km between the stations.

Is there an AI coach?

Not at launch. The forecast, the plan and every change are worked out on your iPhone from rules applied to your own readings, so nothing about your training is sent to an AI service. An optional AI coach is coming back later. It will be off until you turn it on, and the privacy page will say what it sends before it can send anything.

When can I get OLTRA?

It isn't on the App Store yet. Join the beta list and you'll get one email when the beta opens.

What will it cost?

Prices aren't set yet. Joining the beta list costs nothing, and this site will say what OLTRA costs before anything can be bought.

Is it on Android?

Not yet. OLTRA is iPhone and Apple Watch first.

Is OLTRA medical advice?

No. OLTRA is a training tool, not a medical device. It doesn't diagnose anything or tell you whether you're injured. If something hurts, or you're unsure whether training is safe for you, talk to a qualified professional.
