Every workout, program and tracking feature is open the day you download it, on iPhone and on the web. Most apps that call themselves free are freemium, meaning you get a few workouts or a 7-day trial and then a paywall, so check the App Store listing for "In-App Purchases" and the words "trial" or "premium" before you download anything.
How to tell if a workout app is actually free
"Free to download" and "free to use" are different things. Five checks take about a minute:
- Look for "In-App Purchases" on the App Store page. Apple shows it next to the Get button when an app sells anything inside it. If it's there, scroll to the purchase list to see what's locked.
- Search the description for "trial", "premium", "pro" or "unlock". Any of these usually means the core program sits behind a subscription.
- Check whether the plan or the videos are locked. Some apps give you the exercise library free and charge for the thing you actually need: a plan that tells you what to do today.
- Watch for a card prompt at signup. If an app asks for payment details before your first workout, the free part is a countdown.
- Read the ad policy. Some free apps are paid for with ads between sets. That's a fair trade for some people, but it should be your call.
What a free app needs to do to be worth using
Price is the easy part. What matters is whether you're still using it in three months. In a study of 5,240 new members at a fitness center, 63% stopped going within three months and fewer than 4% kept going for a full year (Sperandei et al., 2016). Quitting early is the normal outcome, so the features that matter are the ones that make the next workout easy to start:
- A workout that's already chosen. If you have to build a routine before you can train, you'll skip days.
- Form demos for every exercise, so you aren't guessing.
- Progress you can see, like your best reps and what you did last session, so you know whether to push.
- A streak or history that shows consistency, not only big days.
- Works where you train: home, gym or travel, with or without equipment.
For reference, the WHO recommends adults get 150 to 300 minutes of moderate activity a week plus muscle-strengthening work on at least 2 days (Bull et al., 2020). A free app that gets you to two or three short strength sessions a week covers the strength half of that.

How DO IT pays for itself (the honest version)
DO IT is built by Supliful, a supplement company, and founded by Martins Lasmanis. The app is free. The same team sells an optional product, DO IT Creatine Hydration, in a separate shop. You never need it to use the app, and nothing in the app is locked to buyers. If you want the details before deciding, the product facts page lists every ingredient and the price.

Frequently asked questions
Is there a workout app that's completely free with no subscription?
Yes. DO IT has no subscription, no trial and no premium tier; every workout and tracking feature is free on iPhone and web. Many other "free" apps are freemium, so check the App Store listing for "In-App Purchases" first.
How can I tell if a free fitness app will ask me to pay later?
Look for "In-App Purchases" on the App Store page, and words like "trial", "premium" or "unlock" in the description. A card prompt at signup is the clearest sign.
Why is DO IT free?
DO IT is built by Supliful, which also sells an optional creatine drink in a separate DO IT shop. The app itself has no paywall and doesn't require buying anything.
Does DO IT have ads?
No. There are no ads in the app.
Do I need equipment or a gym?

Is there a free HYROX training app?
Yes: DO IT is a free workout app with no subscription and 67 exercises across 9 categories, and it pairs with our free 8-week Hyrox beginner plan for the run and station work it doesn't build itself. Use DO IT for the strength days and the Hyrox plan (/guides/free-hyrox-beginner-plan) for everything race-specific.
