Runna has 4.9 stars on the App Store from more than 76,000 ratings, and is owned by Strava. For most runners it's a good choice, and this piece isn't trying to talk you out of it.
But some people try Runna and keep looking. The reasons tend to be fairly specific.
(Runna details are from runna.com, September 2026. Features and prices change.)
Why people keep looking
The most common one is wanting someone to talk to. A plan to follow isn't the same thing as a coach who checks in when the week falls apart.
Then there's recovery. Plenty of runners want training that accounts for sleep, resting heart rate and HRV rather than only what the schedule says.
Some already use Intervals.icu and want the coach to read that data instead of building up a fresh history from scratch.
And price. Runna runs $19.99 a month or $119.99 a year.
What Runna does well
Runna is popular for a reason, and it deserves a proper hearing before we get to the gaps.
The plans are well made. Runna Engine builds programmes for everything from 5K to marathon and ultra, with varied sessions and levels from beginner to advanced. You can start without knowing anything about periodisation.
Workouts sync to your watch and guide your pace as you run. That's worth more than it sounds if holding a target pace on your own is hard for you.
Beyond running you get strength and mobility work plus nutrition and form tips. Experienced coaches sit behind the programming, and the community is large and active.
If you want a well-designed plan and pace guidance on your wrist, there aren't many reasons to look elsewhere.
Where it stops
Runna is plan-led. You get a schedule and you follow it. If something needs changing, that's largely on you.
There's a chat in the app, and it's support. You'll get answers about your plan, not a conversation about why today's intervals felt heavy.
The plan adapts to your paces and your schedule, but not to how you slept. Runna reads neither sleep, resting heart rate nor HRV, so that reading is yours to do.
It's built around Strava and watch sync. If Intervals.icu is your hub, none of that helps you.
And there's the price: $19.99 a month is more than twice our $8.49.

Coach Fartlek as an alternative
Coach Fartlek is our own app, so expect some bias. It's built for a narrower group than Runna: runners who take it seriously and are chasing a concrete goal between 5K and the marathon.
The coach reads every workout that syncs from Intervals.icu and reaches out on its own, after sessions and before hard ones. When a week falls apart you say so in your own words and the plan gets rewritten around it. You don't have to translate "slept badly three nights and my stomach is off" into a schedule. That's the coach's job.
HRV, resting heart rate and sleep feed into what you should do next, based on your trend rather than one bad night.
With a Garmin, Coros, Suunto or Polar the coach reads both workouts and recovery through Intervals.icu. That assumes you own a watch. If you don't, Coach Fartlek isn't the right app for you.
Pro costs $8.49 a month, and you get the whole coach free for seven days.
If you're a beginner who mainly wants a clear schedule, pace guidance on your watch and a community to ask, Runna is probably the better first choice. We also don't cover ultra or multisport.
Other alternatives worth knowing
TrainingPeaks goes deep on analysis and suits runners working with a human coach, though it's more a toolset than a coach in itself.
Garmin Coach is free and already sitting in your watch. The plans come from real coaches and adjust difficulty based on how your runs go, which is plenty for a lot of people.
Static plans from a book or PDF are cheap and proven. They don't adapt at all when life changes, which is exactly the point for some runners and the problem for others.

Which should you choose?
Want simplicity and pace guidance on your watch: Runna.
Want a coach that reaches out and rebuilds the plan around how you actually feel, and you already own a watch: try Coach Fartlek.
Have predictable weeks and know how to adjust on your own: a static plan is plenty, and costs almost nothing.
Just want to bounce the occasional question off something: ChatGPT is fine, as long as you know it can't see your training data.
Already have a watch? Setup takes a few minutes. Here's how to connect it via Intervals.icu.
