About this app

UUID Generator Ultimate is the fastest way to generate, inspect, and manage UUIDs on Android.

Generate a UUID in one tap and copy it instantly. Every UUID is saved to your history so you can star, search, and revisit past results without regenerating.

── FREE FEATURES ──
• UUID v4 (random) and v7 (time-ordered, sortable)
• Format options: uppercase, dashes, quotes, curly braces
• Tap-to-copy with visual confirmation
• Recent history inline on the generator screen
• Full history with search, star, and delete

── PRO FEATURES (one-time purchase, no subscription) ──
• Bulk generate up to 10,000 UUIDs at once
• Export as JSON array, CSV, SQL INSERT values, or newline-separated
• UUID Inspector — paste any UUID and decode its version, variant, timestamp, and byte structure
• UUID v1 (timestamp-based) and UUID v5 (DNS, URL, or custom namespace)
• Advanced output formats: URN (urn:uuid:…), curly braces, SQLite X'…' hex
• Unlimited history
• No ads, ever

── UUID INSPECTOR ──
Paste any UUID — standard, URN-prefixed, or braced — and instantly see its version, RFC 4122 variant, embedded timestamp (v1 and v7), and structural byte groups rendered with color-coding.

── BUILT FOR DEVELOPERS ──
All UUID generation runs locally on-device with no network calls. v1 uses a cryptographically random node ID. v5 is computed with SHA-1 over the standard DNS, URL, or a custom namespace UUID you supply. v7 embeds a millisecond-precision Unix timestamp in the high bits for lexicographic sortability.

One-time Pro purchase. No subscription. No nonsense.
