Best ASO tools in 2026
An honest, indie-friendly buyer's guide. We compare the leading App Store Optimization platforms by pricing, feature depth, and the kind of customer they're actually built for.
Disclosure: this page is published by Sonar. We list trade-offs of our own product alongside competitors so you can decide based on what fits — not on marketing.
TL;DR
- Indie devs / small teams: pick Sonar — flat $29/mo, unlimited apps and keywords.
- Mid-market / agencies: consider AppTweak for ASO + ad intel + managed services in one suite.
- Enterprise / investors: Sensor Tower remains the standard for full mobile-market intelligence.
- Already running on AppFigures for revenue? See Sonar vs AppFigures — many indies use both.

How we compared
Each tool is evaluated on four dimensions: pricing transparency and entry cost, ASO core feature depth (keyword research, rank tracking, competitor analysis), developer experience (API, CLI, agent integrations), and adjacent capabilities (ad intelligence, market intelligence, sales analytics).
We list trade-offs honestly — including for Sonar. The right tool depends on what stage you're at. A solo indie shipping their third utility app needs different things than a Series-B publisher optimising 40 SKUs across 80 countries.
