Mini Metal Detector vs QRMaker

Turn your iPhone into a live magnetic-field meter. Watch the reading in microteslas (µT), follow changes in color and revisit your saved scans. Finish a basic or camera scan and save the result directly. Returning to the starting spot for a comparison is optional. Reopen the saved record without making a duplicate, compare two records, or share an image or CSV. Start measuring immediately. Set an optional starting value to follow changes in your surroundings, then use the live graph, color levels, adjustable alerts and haptics to explore the reading. IN VERSION 1.7.1 • Live magnetic-field reading and 60-second history • Adjustable change sensitivity, optional sound and haptic alerts • Starting-value and guided return comparisons • Optional Field Lens: approximate reading points over the camera view • Saved scans, two-scan comparison, image and CSV sharing • Light and dark appearance The meter works without camera access. Field Lens requires a compatible iPhone and camera permission. Camera frames and saved scan contents stay on your device unless you choose to share an export. KNOW THE LIMITS This is a magnetometer app. A changing reading does not identify a metal object, its type or depth. It cannot reliably find gold, silver or every kind of metal, and cannot establish whether drilling is safe. Magnetic cases, speakers, electronics and changes in phone position can affect readings. Camera points are approximate. Requires a magnetometer-equipped iPhone and iOS 17 or later. Free with banner ads; no subscription or account required. App interface: English, Turkish, Spanish, German, French, Brazilian Portuguese, Arabic and Japanese.

QRMaker creates and scans QR codes and barcodes entirely on your device — no server involved. Making one takes a single value, and the background and colors are yours to change. ■ Easy to make, yours to design · Pick a type, type in the value, and the code is ready — nothing else to set up · 30 background themes — each one a gradient with its own pattern · Keep up to 8 favorite backgrounds and bring them back in one tap · Set a brand color from the presets or enter your own, and place your logo in the middle · Whatever background you choose, the code stays on a white panel — it still scans ■ Your printed QR codes never die Most free QR services route scans through their own short URL. When they start charging or shut down, every code you already printed stops working. QRMaker generates codes directly on your device. There is no middleman, so your printed material keeps working even if you delete the app. ■ Built for actual printing · Presets for table stands (85×54mm), A6 stands, and A4 posters · Message templates for review prompts, Wi-Fi instructions, and social follows · Vector PDF export — crisp at any print size ■ The QR codes shops actually use · Review prompt QR (Google, Naver Place, and more) · Table-order link QR · Social follow QR · Guest Wi-Fi QR (scan to connect automatically) · Business card (vCard) QR ■ Batch barcode labels Turn one CSV file into a full sheet of product barcodes, laid out on A4 label stock (3×8 or 2×5) and exported as PDF.
