Week in Review: Apr 27 - May 3, 2026

This week was all about shipping features and refining the development pipeline. The biggest win was the release of SignalKit v0.6.0, which included a unified RTA build with seven new features, including multi-color frequency bars, target traces, and peak-hold hash marks. This update was a significant milestone, and I’m excited to dive into the details of how it came together.

SignalKit v0.6.0: A Major Update

The latest version of SignalKit is a culmination of weeks of work, with a focus on enhancing the Real-Time Analyzer (RTA) feature. The new release includes three color pickers in the Settings menu, allowing users to customize the appearance of the RTA chart. We also introduced multi-color frequency bars with user-defined dB SPL thresholds and colors per zone. This feature was a significant undertaking, requiring careful consideration of how to balance user customization with intuitive design.

One of the most interesting challenges we faced was implementing the target trace feature. This allows users to save current RTA spectra or promote saved measurements, with up to 30 stacked traces and per-trace on/off toggles. To achieve this, we created a new TargetsScreen.tsx component, which handles the rendering and management of these traces. We also had to optimize the performance of the RTA chart to ensure smooth rendering of multiple traces.

In addition to these major features, we also included several smaller but significant updates, such as tap-to-popup frequency bars, peak-hold hash marks, and a pinned readout for typed-in frequencies. These details may seem minor, but they demonstrate our commitment to refining the user experience and making SignalKit an indispensable tool for audio professionals.

Refining the Development Pipeline

While shipping features is always a priority, we also spent significant time this week refining our development pipeline. One notable improvement was the patching of our verify-app.sh, test-app.sh, and build-app.sh scripts to support Android product flavor builds. Previously, these scripts only searched for artifacts in the apk/release/ directory, which caused issues with flavor-specific builds.

To resolve this, we updated the scripts to mirror the behavior of our gitea-release.sh script, which already handled flavor-aware builds. We added a two-line cascade to prefer */play/release/*.apk and fall back to apk/release/*.apk. This change ensures that our pipeline can handle flavor-specific builds correctly, eliminating the need for manual symlinking.

Play Console Listing Rebuild and App Renames

We also spent time this week rebuilding our Play Console listings and renaming several apps. This involved creating new AdMob registrations, deleting stranded drafts, and updating privacy URL slugs. We successfully renamed four apps and created seven fresh Play Console listings, with eight apps pending rollout.

One interesting challenge we faced was dealing with Play API errors due to missing Privacy URLs for certain apps. To resolve this, we established a new rule: set the Privacy URL in the Play Console UI before uploading draft apps with CAMERA or LOCATION manifests via the Play API.

AdSense Fix and Smarthometoolbox.com Updates

Finally, we addressed an issue with Google rejecting our smarthometoolbox.com site for ads. We applied a similar fix to the one used for griswoldlabs.com on April 20, creating new terms and contact pages, adding author bylines, and updating footer links. After deploying these changes via wrangler pages, we verified that the site was live and functioning correctly.

Looking Ahead

As we move forward, our next priorities will be addressing outstanding issues with SignalKit, including audible alarm tones and range modes. We’ll also continue to refine our development pipeline, exploring ways to optimize performance and streamline our workflow.

In addition, we’re considering new features for our tracking app, including enhanced data visualization and export options. While we can’t reveal too much just yet, suffice it to say that we’re excited about the potential for this app to make a significant impact in its respective domain.

Overall, it’s been a productive week at GriswoldLabs, with significant progress on SignalKit and our development pipeline. We’re looking forward to continuing this momentum and delivering even more value to our users in the weeks ahead.
