Spek

Spek is a web-based AI app store optimization (ASO) tool for app founders, mobile growth teams, and ASO agencies that want to improve visibility in the Apple App Store and Google Play.

Key capabilities include:

• Keyword research and opportunity discovery using app-store data, plus competitor analysis by market
• Localized listing drafts that propose metadata changes per selected storefront, language, and market, including estimated visibility lift
• Team review and approval workflows for proposed changes, followed by publishing accepted updates directly to the App Store or Google Play
• ASO analytics for keyword ranking and search visibility tracking, including competitor share of voice

Pricing: Paid. Growth $500/month (5 apps), Pro $2,000/month (10 apps), Scale $5,000/month (25 apps), and custom Enterprise; annual billing saves 20%.

What makes it notable: it positions its ASO workflow around self-learning agents that adapt recommendations based on observed results, and it supports connecting via the official App Store Connect token API so teams can use their own key without sharing an Apple ID password.
