How to Market a Fitness App on TikTok with Slideshows (Step by Step)

TikTok slideshows are the easiest way for a small fitness app to get millions of views without filming anything. They're fast to make, people save them, and the algorithm treats them like any other post.

Here's the exact process.

Step 1: Pick one person and one problem

"Fitness" is too broad. Pick who your app is really for and the one thing they struggle with:

• Beginners who feel lost in the gym
• People who want to lose fat without counting every calorie
• Busy parents with 20 minutes a day
• Runners trying to get faster

Every post should speak to that one person. You'll get fewer random views and far more installs.

Step 2: Use the 3-slide format

Most winning app slideshows follow the same structure:

1. The hook — a pain or a surprising claim, big text, readable in one second.
2. The turn — "So I made / found something that fixes this", or the useful tip itself.
3. The ask — where to get it, with a 👇 pointing to your bio or caption.

Three slides is enough. More slides can work for tips and lists, but the first slide does 80% of the work.

Step 3: Steal these 12 hook formats

• "Stop doing crunches if you want abs"
• "What 1,800 calories looks like at McDonald's vs at home"
• "Your first week at the gym, day by day"
• "I tracked every workout for 90 days. Here's what changed"
• "Gym anxiety? Do this on your first visit"
• "5 exercises that are a waste of your time"
• "How much protein you actually need (it's less than you think)"
• "Too lazy to go to the gym? Do this at home"
• "Why you're not losing weight even though you're 'eating clean'"
• "The 20-minute workout I do when I have no time"
• "Things personal trainers won't tell you"
• "POV: you finally found a workout you don't hate"

Rotate them. Keep a note of which hook each post used, so you can see which ones win.

Step 4: Make the slides look native

Slideshows that look like ads get skipped. The ones that win look like something a real person posted:

• Big, simple text in the middle of the slide — keep it out of the bottom quarter, where TikTok's caption and buttons cover it.
• A photo background that matches the mood: a gym at 6am, a meal prep container, running shoes.
• Or just white text on black. It's a real TikTok format and it's fast to read.

Tools like Alma write and design these from your app's link, so you can make a week of posts in one sitting.

Step 5: Post more than feels comfortable

One post a week won't tell you anything. Aim for 1–3 slideshows a day for 30 days. Most posts will do little; a few will take off, and those tell you what your audience wants.

Post the same slideshows as Instagram carousels too — it's free extra reach.

Step 6: Turn views into installs

Views are only step one. Make the path to your app short:

• Bio link: straight to your App Store page, or one simple web page.
• Caption: repeat the ask — "link in bio 👇".
• Pinned comment: the same line, pinned, on every winning post.

Step 7: Double down on what works

After 30 days, sort your posts by views and by installs. Take the top three hooks and make ten new versions of each — new photos, slightly different wording. This is how small apps go from a few hundred views to a few million: not by finding new ideas, but by repeating the ones that already worked.
