Nobody is born a runner. A marathon is a few hundred unremarkable mornings, added up. Taper makes each one simple: one run, one plain sentence, one small win.
— the idea behind Taper
How it works
From a big, scary goal to today’s easy run.
No spreadsheets, no guesswork. Tell Taper your race and where you’re starting — it turns the whole mountain into one doable step a day.
02
Run today’s one thing
Every morning, one plain sentence: what to run, and why it matters today. The numbers wait behind a tap. That’s the whole job.
03
It adapts, you arrive
Miss a run, sleep badly, feel strong — the plan quietly reshapes itself so your finish line stays exactly where it should: in reach.
Built for 10KHalfMarathon — counted back from your real race date.
The app
Calm by design.
No dashboards shouting at you. No leaderboards. No ads. Just today’s run, your coach’s note and how ready you are — in words first, numbers on tap.
What you get
Everything you need, nothing you don’t.
Four things, quietly working together — so all you have to do is run.
A plan that adapts
Miss a week, catch a cold, feel strong — your training quietly reshapes around your real life.
How it works →A coach in your pocket
A morning “good to go,” a weekly check-in — each in one calm sentence, never a spreadsheet.
Meet the coach →See your own stride
Shop-grade run-form checks from a propped-up iPhone — cadence, symmetry and form, all on your device.
See how →Fuelling, rehearsed
Train your gut like a muscle, so the wall at mile 18 never turns up. Real food words, not lectures.
Why it matters →The coach
The coach who gets it.
Taper watches your training, your sleep and your recovery — then tells you what it means in one calm sentence.
- Morning readinessA gentle “good to go” or “take it easy” each morning, based on how you’ve actually recovered.
- Monday check-insYour coach reviews the week and quietly sets up the next one. No data digging.
- Tell it when something hurtsLog an ache and the plan eases the next hard session for you — then springs back when you feel better.
- Nudges, not nagsNotifications that arrive when they’re useful and stay quiet when they’re not.
Your stride Pro
Your stride, seen.
Until now, seeing your own gait meant a specialist running shop, a treadmill and an appointment. Taper brings that to a propped-up iPhone — run past it, and your form is studied frame by frame. All on your device; your videos never leave it.
Shop-grade. Pocket-sized.
No treadmill, no appointment, no queue — just you, your phone and twenty seconds of running.
Plain words, not physio-speak. Cadence, stride and symmetry — explained like a friend would.
Spot aches early. Small changes in your form often show up before an injury does.
Feeds your coach. Your form becomes part of one honest read: is today a day to push, or to rest?
Fuelling
The wall isn’t fitness. It’s fuelling.
Most first marathons fall apart at mile 18 for one reason: an untrained gut. Taper treats fuelling like a workout — you practise it for months, so race day holds no surprises.
Mile 18
where races are lost — and where Taper runners have a plan they’ve already rehearsed a dozen times.
- A plan, not a lectureWhat to eat and drink before, during and after each key run — in normal food words, grams-per-hour behind a tap.
- Train your gut like a muscleLong runs double as fuelling rehearsals, gradually building what you can take on board.
New to running?
The basics, in plain words.
01
Fuel
Your body stores about 90 minutes of easy running. On anything longer you top up as you go — it keeps the dreaded “wall” away.
02
Shoes
The one bit of kit that really matters. A pair that suits your feet stops small aches becoming injuries. Swap every 500–800 km.
03
Fartlek
Swedish for “speed play”: jog easy, speed up to a lamppost, ease off again. It teaches your legs to change gear.
04
Intervals
Short, faster efforts with a jog between. They build your engine, so your everyday pace starts to feel easier.
05
Strength
Squats, lunges, calf raises, a plank — twice a week, no gym. Strong legs hold your form together when you’re tired.
Taper folds all of this into your plan — you’ll pick it up a run at a time, never all at once.

Made in London
From London, with miles of love.
Tested on Thames-side long runs, rainy commute jogs and one very humbling hill in Greenwich Park. If it can keep you going through a British winter, it can get you anywhere.
Why I built this
Made by someone who needed it too.
I trained for my first marathon with a spreadsheet, a dozen open browser tabs and a low hum of panic. Every app I tried either shouted splits at me or assumed I already knew what a tempo run was.
So I built the coach I wish I’d had — calm, plain-spoken, and honest about the parts most plans gloss over: fuelling, recovery, and the days life gets in the way.
— Sezer Tunca · Taper, London
- Made in Londonby one runner, tested on real long runs — not a growth team’s roadmap.
- Your data stays on your iPhonehealth data and run-form videos are read on your device — never sold, never used for ads.
- No ads, everno leaderboards, no spam — just your training.
Before you ask
The honest answers.
I’m slow, and not very fit. Is this really for me?
Especially you. Taper is built for first-timers, not gym regulars — your plan starts from wherever you honestly are, even “I’ve never run.” The only pace that matters is one you can finish.
Is Taper free?
Downloading Taper and tracking your runs is free, for good. Taper Pro adds your full race plan, the coach, run-form checks and race-day fuelling. Every new runner gets 7 days of Pro free, then it’s a yearly or monthly subscription — your local price is shown in the App Store before you start.
What happens when the free trial ends?
If you do nothing, your subscription starts and the App Store charges your Apple ID. Cancel at least 24 hours before the trial ends — in Settings → your name → Subscriptions — and you won’t be charged. You keep your runs and progress either way.
What if I get injured or miss a week?
Nothing breaks. No red streaks, no guilt trip. Tell Taper something hurts and it eases the next hard session; miss a week and it quietly reshapes the plan around the time you actually have.
Why Taper instead of a human coach — or Runna, Nike Run Club, Couch to 5K?
A good coach watches how you’re doing and adjusts — Taper does that every morning, in plain words. It also takes the parts most plans skip seriously: practising race-day fuelling for months, and backing off when your body asks. No leaderboards, no shouting, no plan that assumes you already know what a tempo run is.
Do I need a running watch or special gear?
Just your iPhone. Taper reads from Apple Health if you let it, and works with Apple Watch if you have one — but nothing’s required. The one thing worth buying is shoes that suit your feet.
Which races can it get me ready for?
10K, half marathon, or the full 42.2 — built backwards from your real race date, whether that’s London in the spring or a local Sunday 10K.
Your start line is closer than you think.
