App
Performance

How StormSync VT/OI has performed during real-world severe weather events. Updated as events occur.

0–2
Poorly Performed
Critical failures — missed alerts, feed drops, crashes, or major parsing errors. The app could not be relied on.
3–4
Below Expectations
Significant bugs or missed products that impacted monitoring. Key functionality unreliable under real conditions.
5–6
Decent Performance
Functioned adequately. Notable issues present but core alert delivery was intact. Room for improvement.
7–8
Performed Well
Strong performance with only minor issues. Feed stable, alerts correct. Small gaps tracked for a future patch.
9–10
Excellent Performance
Near-flawless. Every alert caught, parsed, and displayed correctly. No missed products or errors throughout.

Tornado Emergency — City of Knox

A Tornado Emergency was issued for the City of Knox. StormSync caught and displayed it correctly — rank 115, correct pink color coding, overlay notification fired — ahead of weather broadcasters and community monitors. The first live Tornado Emergency ever processed by the app.

Continuous Feed Stability

The NWWS-OI connection remained stable throughout the event. All tornado warnings, severe thunderstorm warnings, and associated products were received and displayed in real time with no missed alerts or dropped connections.

Tier Color Coding & Severity Ranking

All tornado sub-types were correctly identified and color-coded throughout the outbreak. Severity rankings sorted correctly across simultaneous active warnings.

Upgraded Tornado Warnings Not Displayed

When an existing tornado warning was upgraded during the event, the upgraded product was not reflected as an updated card in the UI. The warning remained visible but the upgrade action was not shown. Known issue — being addressed in v0.0.21 or v0.0.3.

Performed Well
8/10

For a v0.0.2 early beta, performance during this event was strong. Core functionality — real-time feed, VTEC parsing, tier detection, overlay notifications — all worked correctly under live outbreak conditions. The upgrade display issue is the only notable gap and is already tracked for the next release.

This is the first of many events to be listed and rated here. Performance entries will be added after every significant severe weather event as the app continues to be tested in real-world conditions.

Performance entries are added after significant severe weather events. Check back during active outbreak seasons.
