ftns.ai vs Zombies, Run!: A Private Fitness Habit Game vs a Story-Driven Running Game

This Zombies, Run! review is for one reader: someone deciding whether the game is worth paying for. Short answer: if you want a story in your headphones that turns every walk or run into a mission, Zombies, Run! is built for exactly that and is a strong pick. If what you want is one private game about showing up for any training — workouts, walks, rest days and daily logs — ftns.ai, a fitness habit game, may fit better. Plenty of people could use both.

We have already compared ftns.ai with Twinsi, another app built around a digital twin, and explained what a digital twin is. Zombies, Run! is a different kind of gamified fitness: a story you play while you move. So it gets its own honest look.

What is the Zombies, Run! app?

Zombies, Run! is a free-to-start fitness game that turns walking, jogging or running into an audio mission: through your headphones you are Runner 5, collecting supplies, outrunning chases and following a story while GPS tracks your real-world movement.

It first came out in 2012, from Zombies Run! Ltd, and runs on iPhone and Android. On iPhone there is an Apple Watch companion for controlling a run from your wrist — play, pause and replay clips, plus live distance, time and pace — while the phone still runs the mission. It is not a standalone Watch app.

There are 500+ missions across 11 seasons and counting, plus radio mode, interval training, New Adventures and a Couch to 5K / 5K Training programme. Outdoor, indoor and treadmill tracking are all there. It works at any pace, including walking and wheelchair use, and your own music weaves between story clips. Optional chases ask you to speed up, and the supplies you collect help rebuild Abel Township. Co-created by novelist Naomi Alderman; in late 2025 she bought the franchise back, and in May 2026 new story missions resumed under Back From the Dead.

What Zombies, Run! is genuinely good at

• The storytelling is the whole point — immersive audio missions with characters people already love.
• It works at any pace: walk, jog, run, treadmill or wheelchair.
• Your own music stays in the mix between story clips.
• Free to start, with weekly free episode unlocks.
• A deep catalogue: 500+ missions, radio mode, training plans, plus related apps unlocked by the same membership.

It is well liked, too: about 4.8 stars from about 24K ratings on the US App Store, and about 3.9 stars from about 27K reviews on Google Play (both checked 23 October 2026).

Is Zombies, Run! free? What does the membership add?

The app is free to download, and Zombies, Run! unlocks free episodes weekly. A paid membership unlocks the full catalogue across Zombies, Run! and related apps.

On the stores, “Try Zombies, Run! for free” means the free download and those weekly free episode unlocks — not a time-limited trial of the paid membership. Membership is an optional subscription sold monthly and yearly. On the US App Store on 23 October 2026, membership was $6.99 a month or $49.99 a year for subscriptions started from 1 May 2024. Prices can vary by country and store, and Zombies, Run! shows the current cost in the app, so check there before you buy. Membership can sync across iPhone and Android with a Zombies, Run! account.

Membership unlocks the full 500+ mission catalogue, radio mode, interval training and New Adventures, Venture episodes, the full 5K Training programme and all 65 episodes of The Walk.

How do you cancel? Cancel where you subscribed. Deleting the app does not stop payments, and billing stays on the platform you originally bought from.

On iPhone, the steps are:

1. Open Settings and tap your name.
2. Tap Subscriptions.
3. Tap Zombies, Run!.
4. Tap Cancel Subscription.

On Android, Google Play’s steps are:

1. Open your subscriptions in Google Play.
2. Select Zombies, Run!.
3. Tap Cancel subscription and follow the instructions.

Is Zombies, Run! worth it?

It is worth it if a story in your headphones would get you out the door for walks or runs, and the free weekly unlocks are enough to find out. If your real goal is one habit game for every kind of training day, it covers only the days you move with it.

It is a game built around audio missions while you move. If training itself worries you, that is one for a qualified health professional, not an app.

What ftns.ai is for

ftns.ai is a fitness habit game for iPhone with one job: helping you keep showing up. Your twin, a 3D model of you, reacts when you log and rebuilds weekly from what you actually tracked, so one quiet day doesn’t swing it. It is not a body scan; here is what a digital twin is.

One Life Score, 0 to 100, comes from six categories: Nutrition, Training, Recovery, Sleep, Mood and Consistency. You log by hand or let Apple Health fill it in. A run can count; so can a gym session, a walk, a rest day or a daily log. That is the key contrast with a run-story game.

Your coach builds a workout plan when you ask, from your goal, pace, equipment and the exercises you rule out. Offered, never imposed: a finished plan waits in the coach inbox until you choose to add it. Your coach is a game feature, not a health professional.

Missed days slow your progress; they never punish you. Rest isn’t a miss. XP never decreases. Ever. More on that in is it okay to miss a day.

It is also private. No social feed, no friends list, no leaderboards, and your logs and twin live on your phone. That is a design choice, not a dig at Zombies, Run!. More in why there is no social side.

Who should pick which

• Pick Zombies, Run! if you love story-driven runs, headphones make you move, you want something free to start with weekly unlocks, you are on Android, or you want a deep mission catalogue.
• Pick ftns.ai if you want one game for your whole routine, not only runs; any workout, walk or rest day to count; a coach who builds a plan when you ask; and something private.
• Use both if you want Zombies, Run! for the days you walk or run with a story, and ftns.ai to keep the wider habit visible. Apple Health can pick up activity; the two apps don’t share data with each other.

A Zombies, Run! alternative for your whole fitness habit

If what you want is one private game that reflects showing up for any kind of training, a fitness habit game fits better than a run-story game.

If that sounds like you, try ftns.ai on iPhone. It is a paid iPhone membership, free for 7 days, then $14.99/mo or $167.99/yr, so you can see whether showing up for your twin sticks before you pay.

One game turns every run into a mission. The other just wants you back tomorrow.
