Track iOS app sizes with trend alerts using Google Sheets and Gmail notifications

IPA Size Tracker with Trend Alerts – Automated iOS Apps Size Monitoring

This workflow runs on a daily schedule and monitors IPA file sizes from configured URLs. It stores historical size data in Google Sheets, compares current vs. previous builds and sends email alerts only when significant size changes occur (default: ±10%). A DRYRUN toggle allows safe testing before real notifications go out.

Who’s it for

- iOS developers tracking app binary size growth over time. - DevOps teams monitoring build artifacts and deployment sizes. - Product managers ensuring app size budgets remain acceptable. - QA teams detecting unexpected size changes in release builds. - Mobile app teams optimizing user experience by keeping apps lightweight.

How it works

1. Schedule Trigger (daily at 09:00 UTC) kicks off the workflow. 2. Configuration: Define monitored apps with {name, version, build, ipaurl}. 3. HTTP Request downloads the IPA file from its URL. 4. Size Calculation: Compute file sizes in bytes, KB, MB and attach timestamp metadata. 5. Google Sheets: Append size data to the IPA Size History sheet. 6. Trend Analysis: Compare current vs. previous build sizes. 7. Alert Logic: Evaluate thresholds (>10% increase or >10% decrease). 8. Email Notification: Send formatted alerts with comparisons and trend indicators. 9. Rate Limit: Space out notifications to avoid spamming recipients.
