Short answer
The best treadmill app for weight loss is the one you will use most weeks. iFIT suits people who want trainers to control speed and incline on NordicTrack or ProForm. Peloton suits class lovers. Zwift and Kinomap make long sessions less boring. A free brand app plus a written plan works if you only need tracking.
Key takeaways
- The best treadmill app for weight loss is the one you will use consistently.
- Digital self-monitoring is consistently associated with weight loss in research.
- iFIT offers the most automatic treadmill control, on NordicTrack and ProForm only.
- Peloton is strongest for live and on-demand classes.
- Zwift and Kinomap make long sessions more engaging; Zwift does not control the treadmill.
- A free brand app plus a written plan is a solid no-subscription option.
A treadmill app cannot burn calories for you, but it can make it easier to show up, push a little harder and keep an honest record. That is what matters for weight loss. The CDC puts it plainly on its physical activity and weight page: getting to and staying at a healthy weight requires both regular physical activity and healthy eating patterns.
This guide compares the main types of treadmill apps, from trainer-led platforms like iFIT and Peloton to game-style Zwift, real-world video in Kinomap and the free apps that come with many treadmills. Feature descriptions come from each company’s official pages and from the treadmill listings in our reviews. Membership terms change often, so check the current terms before you sign up. For the training side, pair this with our how to lose weight on a treadmill guide.
What a Treadmill App Can and Cannot Do for Weight Loss
The strongest evidence for apps is about tracking. A 2021 systematic review in Obesity of 39 randomized trials found that self-monitoring through digital health tools was consistently associated with weight loss in behavioral obesity treatment. An app that logs every session, and ideally your food and weight too, supports that habit.
Apps also help with consistency and intensity. Trainer-led classes, structured plans and virtual routes give you a reason to start and a target for each session. The CDC activity guidelines for adults call for at least 150 minutes a week of moderate activity such as brisk walking, and the CDC adds that some people need more to keep weight off.
What an app cannot do is replace diet changes or make weight loss fast. The NIH warns about programs that promise large losses in a few weeks or weight loss without diet or exercise. Be skeptical of any app that does.
Treadmill Apps Compared at a Glance
The table compares the main options by what they do best and whether they can control the treadmill. Automatic control matters more than it sounds: when the app changes speed and incline for you, you follow the workout instead of pressing buttons, and many people work harder as a result.
| App | Style | Controls the treadmill? | Works with |
|---|---|---|---|
| iFIT | Trainer-led workouts, adaptive plans, map routes | Yes, speed and incline on compatible machines | NordicTrack and ProForm treadmills |
| Peloton | Live and on-demand instructor classes | On Peloton hardware; tracking only on third-party FTMS treadmills with App+ | Peloton Tread; other treadmills via the app |
| Zwift | Game-style virtual worlds and group runs | No, per Zwift | Treadmills that connect directly, or a foot pod or watch |
| Kinomap | Real-world route videos | Incline only, on Interactive equipment | Bluetooth treadmills; sensors for others |
| JRNY | Adaptive workouts and coaching | On compatible Bowflex machines | Bowflex T7; Schwinn models list JRNY via tablet |
| Free brand apps (SOLE+, XTERRA Fitness, SunnyFit, FitShow) | Tracking, some programs or classes | Varies by model | Their own brand’s treadmills |

iFIT: Best for Hands-Off, Trainer-Led Workouts
iFIT is the platform behind NordicTrack and ProForm. The listings in our reviews describe trainer-led workouts that automatically control speed and incline, SmartAdjust, which adapts your workouts based on your history, ActivePulse, which keeps you in a target heart-rate zone using a Bluetooth monitor sold separately, Google Maps route workouts, an AI Coach by text message and syncing with Strava, Garmin Connect and Apple Health.
For weight loss, ActivePulse and SmartAdjust are the standouts because they keep effort in a useful range without constant button pressing. NordicTrack’s membership guide describes two tiers: iFIT Train for phone and tablet use by one user, and iFIT Pro for built-in touchscreens with multiple profiles. LCD models such as the NordicTrack T Series 7 list iFIT Train; touchscreen models such as the NordicTrack T Series 16 list iFIT Pro.
The limit is lock-in. iFIT’s automatic control works on NordicTrack and ProForm equipment, and without a membership those treadmills run in manual mode. Our T Series 7 review explains what the treadmill does without it.
Peloton: Best for Class-Driven Motivation
Peloton’s strength is its instructors and class library. On a Peloton Tread, the All-Access Membership unlocks live and on-demand classes and personalized weekly plans on the swivel touchscreen. Peloton states that Just Run works without a membership, but the classes do not.
You do not need Peloton hardware to use Peloton classes. According to Peloton, App One includes unlimited outdoor running and walking classes and a limited number of equipment classes each month, while App+ includes unlimited equipment classes and can connect to a third-party Bluetooth FTMS treadmill to track your workout. Peloton states that owners of its own Tread need All-Access instead.
If live classes and a leaderboard push you to keep going, Peloton is a strong choice. If you mainly want treadmill control, iFIT does more of the work for you. Our best treadmill with classes guide compares the Tread with iFIT models.
Zwift and Kinomap: Best for Making Long Sessions Fun
Long, steady sessions are a good fit for weight loss, but they can be dull. Zwift turns them into a game with virtual worlds, workouts and group runs. Zwift says all you need is a speed sensor and the app: either a treadmill that connects directly or a supported foot pod, smart shoe or smartwatch on nearly any treadmill. Zwift’s own article on smart treadmills notes that a foot pod usually reads slower than the treadmill, and that automatic incline or speed control has not yet been implemented.
Kinomap uses real-world route videos filmed by contributors. Its support pages divide equipment into three types: Classic machines with no Bluetooth need an external sensor, Smart machines send data but you set incline yourself, and Interactive machines let Kinomap adjust incline or resistance to match the video. Check Kinomap’s compatibility list for your model.
Among the treadmills we review, the THERUN X1 listing names FitShow, Kinomap and Zwift, and the Schwinn SFT4.3 names JRNY, Peloton and Zwift. Testers and owners of the Horizon 7.4 AT mention pairing it with Zwift and Peloton.
Pro tip: If your treadmill does not connect to an app, a foot pod or a watch can still feed Zwift or Kinomap. Calibrate it against the treadmill display so your distance stays honest.
Free Brand Apps and No-Subscription Setups
Many treadmills come with a brand app that needs no paid plan. Our reviews list SOLE+ on the Sole F65 and Sole F80, the XTERRA Fitness App on the XTERRA TR75, SunnyFit on Sunny Health & Fitness models and FitShow on several walking pads. Independent testers of the Sole F89 found free classes in the SOLE+ app. Feature sets vary, so check what the app does for your model.
A no-subscription setup can be just as effective for weight loss if you supply the structure. Use built-in programs or a simple written plan, log each session, and track your weight and food in any app you like. Our 12-3-30 treadmill workout, treadmill HIIT workouts and treadmill pace chart guides give you ready-made sessions.
Treadmills built for this approach lead our best treadmill without subscription guide, starting with the Horizon 7.0 AT, which also ranks first in our best treadmill for weight loss guide.

Start with what has stopped you before. If you skip workouts because you do not know what to do, choose guided classes. If you get bored, choose Zwift or Kinomap. If you dislike recurring plans, choose a treadmill that works fully without one and use a free app for tracking.
Then check compatibility before you buy the treadmill. iFIT control needs NordicTrack or ProForm equipment, Peloton classes on a third-party treadmill track best with Bluetooth FTMS support, and Kinomap incline control needs Interactive equipment. If an app requires a membership, read the renewal terms; the FTC explains how free trials and auto-renewals work.
Finally, treat calorie counts as rough guides. Apps estimate calories from your weight, speed and incline, and the numbers can differ between apps. Our treadmill calories burned guide explains the formulas.
- Wants a coach in control: iFIT on a NordicTrack or ProForm treadmill.
- Loves live classes: Peloton on a Peloton Tread, or Peloton App+ on another treadmill.
- Gets bored easily: Zwift or Kinomap.
- Wants no recurring plan: a free brand app plus a written plan.

Check Price on AmazonChecklist Before You Choose an App
- Decide whether you need guided classes, entertainment or tracking only.
- Confirm the app works with your treadmill brand and model.
- Check whether the app can control speed and incline on your machine.
- Look for logging that you will actually review each week.
- Check whether the app syncs with the health or watch app you already use.
- Read the membership and renewal terms before you start any trial.
- Plan your diet changes alongside the app; exercise alone is slow for weight loss.
- Treat calorie estimates as rough guides, not exact numbers.
Common Mistakes to Avoid
- Buying a treadmill for an app it does not support.
- Expecting an app to deliver weight loss without changes to eating habits.
- Trusting calorie counts as exact and eating them back.
- Paying for a platform but using only manual mode.
- Letting a trial roll into a membership you did not plan to keep.
- Switching apps every few weeks instead of building one habit.
The Bottom Line
- A 2021 systematic review found that self-monitoring through digital tools was consistently associated with weight loss in behavioral programs.
- The CDC notes that reaching and keeping a healthy weight takes both regular physical activity and healthy eating patterns.
- iFIT can change speed and incline on compatible NordicTrack and ProForm treadmills; Zwift states that automatic treadmill control is not yet implemented.
- Kinomap can adjust incline only on equipment it classes as Interactive; on Smart and Classic machines you change settings yourself.
- App calorie numbers are estimates; see our treadmill calories burned guide for how they are calculated.
