About Rank Sonar

We're building the ASO tracker we wished existed when we were shipping mobile apps ourselves: honest pricing, daily-fresh data, and AI that actually tells you what to do next.

Our beliefs

1. Daily data, or it doesn't count. Weekly tracking is theater. The app stores move every day; your tracker needs to as well.
2. Honest pricing beats per-keyword bullshit. We will never charge you based on how many keywords you track. The infrastructure cost difference is real, and we absorb it.
3. AI should explain itself. Every Copilot recommendation comes with the rationale Claude used to generate it. No black-box scores.
4. Indie devs deserve enterprise tools. The $29 Solo tier is not a throwaway — it gets the same scrapers, the same AI infrastructure, the same data freshness as the $199 plan.

Stack

Marketing site is Next.js 16 on Vercel. The app runs on Expo SDK 54 (iOS, Android, web) backed by Supabase Postgres + Auth. Scraping happens in Vercel Sandbox using rotating ScrapingBee residential proxies. AI is Claude Haiku and Sonnet via the Vercel AI Gateway. Workflows are durable via Vercel Workflow DevKit. Email is Resend. Mobile payments via Superwall + RevenueCat; web payments via Stripe.
