ToolBox v1.4.5

Launch crash fixed. On some phones the app closed instantly on opening — a Google library file that the ads SDK needs was missing from the build. It is now included in full, and the app opens normally.

Age Calculator improved: the date now types itself in dd-MM-yyyy format with dashes added automatically, the keypad is numbers-only, and a wrong date shows a plain, friendly message instead of a technical error.

v1.4.3 — Sensors category + launch-crash fixes

⚠️ DOWNLOAD PAUSED — this build crashes on launch on some devices. A fixed build is coming; please do not install this version.

What's new

Sensors category — 6 new tools (108 tools total)
Spirit Level • Compass • Sound Meter • Light Meter • Metal Detector • Barometer

Fixes

• Launch crash on some devices: content setup now retries safely, and folding/unfolding on foldable phones no longer restarts the app into the failing path
• Compass rebuilt on the fused rotation-vector sensor — steadier and faster
• Metal Detector now learns the normal magnetic field around you and alerts on the rise — small iron objects are detected much better
• Back button: tool → back to the same category → Home → "Exit ToolBox?" confirmation
• Settings and About show only the version name in public builds
