The other side
When to choose FoxData instead
For pure App Store and Google Play ASO across several apps, Sonar does the core job at $29/month flat. FoxData is the pick when you also want download and revenue estimates, ad and market intelligence or Steam charts in one place — or when its $9.90 Starter plan covers you.
Where FoxData is stronger
Built for: Growth teams that want download estimates and ad and market intelligence alongside ASO, starting from a free plan.
- Free plan, and paid plans from $9.90/month
- Download and revenue estimates
- Ad and market intelligence beyond keyword tracking
- Data API with a free tier of 10,000 calls a month
- Steam Charts module for PC games
What Sonar doesn't do
- No ad or market-intelligence reports; Ad Spy shows tracked competitors' Meta ads and TikTok posts only.
- No download or revenue estimates beyond rough per-app revenue figures, and no Steam data.
- A higher entry price than FoxData's $9.90 Starter, and no free dashboard plan.
- Apple reports a popularity of 5 for most long-tail iOS searches, so Sonar's number below that floor (and every Google Play popularity) is its own calibrated estimate, not an Apple figure.
- Sonar is young and founder-led: keyword history starts when Sonar began tracking a term (2026 at the earliest), and there are no account managers or managed services.

FAQ
Sonar and FoxData, answered
Yes. Sonar covers the ASO core most teams use FoxData for — keyword research, rank tracking and competitor analysis — at a flat $29/month covering 10 apps and 2,500 keywords. FoxData adds download and revenue estimates, ad and market intelligence and a Steam Charts module that go beyond Sonar's Ad Spy (competitors' Meta ads and TikTok posts).
FoxData has a free plan and paid plans at $9.90/month (Starter), $59 (Standard), $159 (Growth) and $399 (Pro), with Enterprise from $399. All plans have a 7-day trial; yearly billing is 15% off.
It depends on the plan. FoxData's free plan and $9.90 Starter cost less than Sonar; its $59 Standard plan costs about twice Sonar's $29/month Indie plan, which covers 10 apps and 2,500 keywords. If you only need ASO across several apps, Sonar is usually cheaper; FoxData costs more as you add download, ad and market intelligence.
No. Sonar covers the Apple App Store and Google Play only. FoxData has a Steam Charts module, so if PC-game charts are part of your work, FoxData covers them and Sonar does not.
