StoreKit 2 Renewal Auditor

Problem Context

Developers building subscription-based macOS apps rely on StoreKit 2’s real-time streams to track renewals. These streams often break during scene changes or async loops, causing renewals to go unnoticed. Without fixes, devs lose revenue and waste hours manually verifying payments.

Pain Points

StoreKit 2 streams randomly stop firing after the first purchase, forcing devs to keep listeners alive across scenes—an unreliable workaround. Async loops make debugging impossible, and manual checks are time-consuming. No native tools or docs explain how to fix this, leaving devs stuck with brittle solutions.

Impact

Unverified renewals mean lost revenue, and manual checks waste 5+ hours weekly. Devs lose trust in their systems and fear missing critical payments. The risk of undetected revenue loss is too high to ignore, but fixing it requires deep technical knowledge most devs don’t have.

Urgency

This is a mission-critical issue for subscription-based apps. Without real-time renewal tracking, devs can’t trust their revenue numbers or scale their businesses. The problem occurs daily, and manual workarounds are unsustainable—automation is the only viable solution.

Target Audience

Indie SaaS founders, macOS app developers, and teams building subscription-based apps on Apple’s platform. Any developer using StoreKit 2 for real-time transaction monitoring faces this problem, especially those with complex async workflows or frequent scene changes.

Solution Approach

RenewalGuard is a lightweight macOS agent that continuously monitors StoreKit 2 streams for disconnections. When a stream drops, it auto-reconnects and logs all events for auditing. Devs get a dashboard to track renewals in real time and export logs to verify revenue—no manual checks needed.

Key Features

1. Audit Logs: Records every subscription event (purchases, renewals, failures) for revenue verification.
2. Real-Time Dashboard: Web app to monitor subscription status and set up alerts for anomalies.
3. CLI Tool: Simple setup and manual reconnects for devs who need control.

User Experience

Devs install the agent once, then forget about it. The dashboard shows renewals in real time, and logs are exported monthly for audits. Alerts notify them if streams drop, so they can act fast. No more manual checks—just reliable, automated renewal tracking.

Differentiation

Unlike free tools or Apple’s docs, RenewalGuard is built *for- StoreKit 2’s undocumented quirks. It auto-reconnects streams (no manual fixes) and provides audit logs (critical for revenue trust). No other tool solves this exact problem—devs are stuck with manual workarounds or lost revenue.

Scalability

Starts with a single-seat plan ($49/mo) and scales to team plans ($99/mo/seat) with API access for larger apps. Audit logs grow with usage, and alerts can be customized for teams. The agent runs in the background, so it doesn’t slow down as the app scales.

Expected Impact

Devs regain trust in their revenue numbers and save 5+ hours weekly on manual checks. Auto-reconnects prevent lost renewals, and audit logs provide proof for disputes. The dashboard gives visibility into subscription health, so devs can focus on growth—not fixing broken streams.
