CarTrackLog

CarLogs is a private, offline-first iOS app (SwiftUI + GRDB/SQLite) for tracking your car's fuel fills, maintenance, oil checks, and expenses — all data stays on-device with no servers, ads, or tracking. Key features: Records: fuel (auto-calculates price/L and L/100km), maintenance, oil checks (refills never count as expenses), and expenses — all editable/deletable, with optional notes. Oil tracking: status banner (OK/due/overdue) and a local reminder 25 days after last oil check. Stats & charts: expense breakdown, fuel consumption, fuel price trends, monthly mileage, oil refill history (Swift Charts). Settings: 8 currencies, EN/CHINESE/SPANISH switching, custom categories, full SQLite export/import (validated, replace-all on import). Privacy: 100% on-device; import/export is the only way data leaves the phone. Requirements: iOS 27+, iPhone/iPad. Dev setup uses xcodegen + Xcode. Proprietary license.
