Key Features Model Identification · Q&A-Based Precision Answer simple questions about camera count, screen shape, bezel style, and other physical features to progressively narrow down possibilities and pinpoint the exact phone model.

Save to Photos or share with friends—perfect for second-hand transactions, accessory purchases, or helping family members identify their phones. Recognition History All identification results are automatically saved. Copy model names with a tap. History is displayed in reverse chronological order for easy review and sharing. Screen Touch Test · Preliminary Integrity Assessment Tap a full-screen grid to test touch responsiveness across every area of your screen. Real-time progress shows how many areas have responded. Tap the checkmark button to view your current touch integrity rate. Quickly assess screen condition when buying, repairing, or just checking your device.

Technology with warmth. Every phone, understood.

Verdict
The clearest difference is in-app purchases: iSpector at none against Screen Test's 1. iSpector also leads on ads (none vs shown). Screen Test's advantage is update cadence (weekly vs every 4 months). On price, device support and iOS requirement there is nothing between them.
