FAQ
What does this tool tell you?
The App Size Budget Calculator assesses app install size against iOS and Android thresholds with App Thinning and App Bundle optimization recommendations.
What affects the result most?
iOS App Store download limit: 200MB over cellular — above this shows cellular warning. App thinning: bitcode + slicing delivers only required architecture and assets per device. Android App Bundle: Play delivers only resources for device density and ABI — reduces install size ~40%.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
