7 Best Free Mobile App Competitor Analysis Tools (2026 Ranked)
The mobile app market in 2026 is ruthless. With millions of AI apps, games, and utilities launching every month, simply having a "good idea" is no longer enough. To survive, you need data.
You need to know:
- How much money is your competitor making?
- Which keywords are driving their downloads?
- Are they growing or dying?
Many developers assume they need to pay $10,000/year for enterprise software like Sensor Tower or data.ai (now part of Sensor Tower) to get these answers. That is a myth.
In this guide, we have curated the 7 best free (and freemium) mobile app competitor analysis tools available in 2026. Whether you are an indie developer building the next ChatGPT wrapper or a marketer optimizing your ASO, these tools will give you the "spy" powers you need without breaking the bank.
What is Mobile App Competitor Analysis?
Competitor analysis is the strategic process of evaluating your rivals to identify their strengths, weaknesses, and market positioning. Unlike general web SEO tools (like Semrush or Ahrefs), mobile app analytics focus specifically on App Store and Google Play metrics.
Effective analysis helps you answer:
- Revenue & Downloads: Is the niche profitable?
- ASO Strategy: What keywords are they ranking for?
- Feature Updates: What new features are they testing in their latest version?
Top 7 Free & Freemium Competitor Analysis Tools (2026)
Here is our ranked list based on data accuracy, ease of use, and "free tier" generosity.
1. Appark (Best Overall for Revenue & Trends)
Appark has emerged in 2026 as the go-to platform for indie developers and SMEs. While big players focus on enterprise contracts, Appark democratizes data with a powerful self-service model.
- Best For: Tracking real-time charts, estimating revenue/downloads, and spotting pre-order trends.
- Free/Freemium Features:
- Global Top Charts: View real-time rankings for any country/category.
- Pre-order Radar: The only tool on this list that specializes in finding unreleased apps currently in pre-registration (a huge advantage for catching trends early).

2. Sensor Tower (The Enterprise Giant)
Sensor Tower is the industry standard. After acquiring data.ai (formerly App Annie) in 2024, it became the largest data provider in the world.
- Best For: Enterprise-grade accuracy and ad intelligence.
- Free Features: Their free tier is limited but useful for checking "Top Charts" and basic category rankings. However, deep revenue data usually requires a "Let's Talk" sales call.
3. MobileAction (Best for ASO Keywords)
If your primary goal is App Store Optimization (ASO)—getting your app to rank for specific keywords—MobileAction is a strong contender.
- Best For: Keyword tracking and "Keyword Spy."
- Free Features: They offer a "Free Forever" plan that allows you to track a limited number of keywords and see basic visibility scores.
4. AppTweak (Data Visualization)
AppTweak is known for its beautiful interface and "ASO Timeline" feature.
- Best For: Visualizing metadata changes over time.
- Free Features: They offer a 7-day free trial, which is great for a one-off deep dive audit, though not a permanent free solution.
5. SimilarWeb (Best for Cross-Platform)
Does your competitor have both an App and a Website (e.g., Duolingo or Airbnb)? SimilarWeb is unique because it tracks both.
- Best For: Understanding traffic sources (e.g., how many users come from Google Search vs. Direct).
- Free Features: Their free browser extension provides quick traffic estimates for websites, and their platform offers basic app ranking data.
6. AppFigures (Developer Friendly)
AppFigures started as a tool for developers to track their own sales but expanded into market intelligence.
- Best For: Tracking your own app's performance alongside competitors.
- Free Features: Good tools for tracking reviews and ratings.
7. Google Play Console / App Store Connect (The Source)
Don't forget the official tools! While they don't show competitor revenue, the "Peer Benchmarks" section in Google Play Console can tell you how your retention and crash rates compare to "similar apps."

Step-by-Step Guide: How to Spy on Competitors Using Appark
Let's say you want to launch an AI app in 2026. You are worried about competing with giants like ChatGPT or Google Gemini. Here is how you use a free competitor analysis tool to find your gap.
Step 1: Filter the Noise with Advanced Search
Don't just look at the "Top 10" list. The Top 10 is dominated by giants. You need to find the "Mid-tier" winners—apps making $50k/month that you can actually compete with.
Use Appark's Advanced Search to filter by:
- Keywords: "AI Chat" or "Photo Editor"
- Revenue: $10,000 - $100,000 (The sweet spot)
- Release Date: Last 6 months (To find new rising stars)
Step 2: Analyze the "Revenue War"
Once you find your competitors, you need to know: Are they stable?
In the chart below, we compared ChatGPT (Blue), CapCut (Red), and Duolingo (Yellow).
- The Insight: Notice how the Blue line (ChatGPT) grows aggressively? That is a "Utility" growth curve.
- The Opportunity: Look at the Yellow line (Duolingo). It is slow and steady. If you are an indie developer, building a "Gamified" app (like Duolingo) might be a safer bet than fighting the "AI Utility" war against OpenAI.
Step 3: Check Their Version History
Go to the App History tab on Appark.
- Did they just update their title? (They are testing new SEO keywords).
- Did they change their screenshots? (They are trying to improve conversion rates).
- Action: If a competitor changes their title to include "Free AI Writer," you should test that keyword too.
FAQ: Mobile App Analytics
Q: Can I really get competitor revenue data for free?
Most "Free" tools only give you rankings (e.g., #5 in Education). Appark is one of the few platforms that provides revenue estimates and broad market data in its accessible tier, helping you gauge if a competitor is making $5k or $500k.
Q: How accurate are these revenue estimates?
No tool is 100% accurate except the developer's own bank statement. However, tools like Appark use sophisticated algorithms based on ranking position, review velocity, and IAP (In-App Purchase) price points to estimate revenue with high confidence for trend analysis.
Q: Is Sensor Tower free?
Sensor Tower has a free tier, but it is very limited. You can see top charts, but you cannot see revenue estimates or detailed historical data without a significant enterprise subscription.
Q: How do I find apps that haven't launched yet?
This is a secret weapon. Use the "Pre-order" filter in Appark. This shows you apps that are currently marketing themselves but haven't hit the store yet. Analyzing these gives you a "First Mover Advantage."
Conclusion
In 2026, you don't need a corporate budget to make data-driven decisions.
- Use MobileAction to find keywords.
- Use SimilarWeb to check website traffic.
- Use Appark to track Revenue, Downloads, and Pre-orders.
The best "free" tool is the one that gives you actionable data, not just vanity metrics. Start by auditing your top 3 competitors today, and you will uncover opportunities they missed.
