CrossMath

Place numbers into an arithmetic grid, solve clean equations, and come back tomorrow with a better streak.

Easy, medium, and hard boards are generated from a puzzle engine with operators that scale from addition to full arithmetic.

The app tracks current play, weekly solved and skipped activity, and streak momentum without turning the interface into clutter.

The experience is built around fast sessions: choose a difficulty, solve the grid, and keep moving.

Photo cleanup

Review photos and videos, keep what matters, and stage media for device deletion with a local-first workflow.

Fotolo reads media you grant access to so you can move through albums, random media, photos, and videos without creating a cloud account.

Items marked for removal stay staged for review before you confirm any final system delete action from your device library.

The app keeps its media index, cleaning decisions, completed sections, and saved-space stats on the device.
