If you’re running paid campaigns or optimizing your App Store presence, one of the fastest ways to improve your ad results is by learning from what’s already working. So here’s a guide to help you.
And good news: you no longer need to guess what your competitors are doing.
Whether it’s Apple Search Ads, TikTok, or YouTube Shorts, a whole ecosystem of ad libraries and repositories now exists to help you spy top-performing creatives, study messaging trends, and steal with pride (and purpose).
In this guide, we’re sharing the top free ad repositories + a few paid tools we actually recommend, because they help you move faster, smarter, and with more creative confidence.
Start with the Free Tools: Official Ad Libraries by Platform
Let’s start our guide with the basics. Most major ad platforms now offer a level of ad transparency, letting you search what’s currently running and working across Meta, Google, TikTok, Pinterest, and yes, even Apple.
These are often underrated by marketers, but they’re a goldmine if you know how to use them.
1. Apple Ad Repository
Apple Ad Repository now shows all ads running across its own apps, like the App Store, Apple News, and Stocks. If you’re running Apple Search Ads campaigns, this tool lets you:
- See who’s running ads
- Analyze seasonal creative trends
- Track how apps promote features or subscriptions in their headline
It’s especially useful for identifying what kind of messaging Apple features in its ecosystem (clean, native-looking, value-led), so you can focus on performance.
2.Meta Ads Library
The OG. Meta’s Ad Library is still one of the most powerful tools to dig into what your competitors are doing.
You can:
- Search by brand name
- Filter by platform, format, region, or even keywords
- See all live and inactive ads
Tip: Look for how brands test multiple headline-image combos. It’s a free lesson in creative iteration.
3. Google Ads Transparency
This one’s great if you want to see what’s running across YouTube, Google Search, Gmail, and Display.
With Google Ads Transparency, you can search by advertiser, region, and type.
Especially relevant for SaaS, fintech, productivity, and AI apps running video + display campaigns.
4. TikTok Creative Center / Ads Library
TikTok recently stepped up its transparency game. The TikTok Creative Center / Ads library lets you view:
- Performance driven video ads by country, industry, or format
- Trends in hooks, captions, and audio
- Real stats on views, likes, and shares (when available)
Bonus: You can also browse trending TikTok songs, effects, and hashtags, all in one place.
5.Pinterest Ads Repository
Yes, Pinterest has an ads library too, the Pinterest Ads Repository, perfect if you’re in beauty, home decor, travel, wellness, or fashion. Search by keyword or brand name to view Promoted Pins, see what CTAs are used, and how visuals are styled.

The platforms above give you transparency, but what if you want to go deeper? Filter by performance, get alerts, or generate ideas from AI?
Here are two premium tools we actually use and recommend, to make the most of your ads campaigns.

It’s not cheap, but if you’re managing spend at scale, it can more than pay for itself.

Why Creative Research isn’t just Nice-to-Have
Here’s the truth: we’re not in the media-buying era anymore. Creative is your performance multiplier.
The difference between a 1% CTR and 5% CTR? It’s not your bid, it’s your ad.
Studying what works gives you:
- A faster testing cycle
- Higher ROAS with fewer ad experiments
- A way to train your team or freelancers
- A bank of proven hooks, layouts, and formats to remix
Whether you’re building new Apple Ads screenshots, launching UGC ads, or just optimizing your Meta Ads, having a swipe file of high-performing ideas puts you 3 steps ahead.
How to use these Repositories like a Pro
Here’s our go-to workflow for using ad libraries when working on a new campaign or ASO launch:
- Pick your top 3 competitors (or indirect ones targeting your audience).
- Use Meta / TikTok / QuickAds to collect 5–10 creatives per app or brand.
- Analyze:
- What’s the hook in the first 3 seconds?
- What pain point or desire is being tapped?
- What kind of testimonial or UGC structure is used?
- Use AI (QuickAds or ChatGPT) to generate new versions tailored to your app or brand voice.
- Test variations → Scale what wins.
Pro Tip: Save top ads in a Notion swipe file, organized by vertical and emotional angle (trust, joy, fear of missing out, curiosity, etc.).
