Sonar - ASO tool
About Sonar - ASO tool
Sonar is an ASO (App Store Optimization) tool designed for indie developers, providing keyword research, rank tracking, and competitor analysis for both iOS and Android platforms. It enables users to find keywords they can realistically rank for by offering data such as search volume, difficulty scores, and autocomplete suggestions. The tool also includes daily rank tracking to monitor app performance and allows for competitor analysis to identify high-opportunity keywords that competitors may be targeting but the user is not.
Sonar is a focused, cloud-based app store optimization product founded in March 2026 in SK and already has paying customers and recurring revenue ($1,140). Drawing 764 monthly visitors into a subscription funnel at this early stage suggests initial product-market fit, though the revenue base is still small.
The 30-day growth rate of +81% is the headline — it signals either successful early marketing or a recent pricing/feature win that accelerated conversions. The immediate priorities to make that growth meaningful are scaling visitor acquisition, improving conversion and retention, and proving that the growth can be sustained beyond short-term spikes.
