CASE STUDY
Consumer Fintech App (120k MAU)
The team had frequent scroll jank and a cold-start median of 3.6s on mid-range Android devices.
FlutterTune surfaced rebuild-heavy list cells, expensive image decode spikes, and blocking startup initialization paths.
Results
01
Startup time reduced from 3.6s to 2.4s
02
Janky frames dropped from 12.8% to 4.9%
03
P95 frame build time improved by 37%
