QR Forge vs DataFastView

QR Forge makes QR codes — and then proves they work. Every other generator draws your code and hands it over. QR Forge reads its own work back first. After the artwork is rendered — rounded modules, a gradient, your logo through the middle — the app samples that finished drawing the way a camera does and runs it through a complete Reed-Solomon decode. If your content doesn't come back exactly as you typed it, you are told before you export anything. You get numbers, not a badge: • Whether the code decoded back to your exact content • How much of the error-correction budget your styling spent • How it holds up across five off-centre reads, the way a phone sees a code photographed at an angle • Mark strength, contrast ratio, quiet zone and logo coverage • The smallest size you can safely print it FOURTEEN KINDS OF CODE Link, Text, Wi-Fi, Contact card, Email, Message, Phone, Location, Calendar event, WhatsApp, Social profile, App listing, Crypto payment, and Raw for typing a payload byte for byte. Wi-Fi passwords and contact names containing punctuation are escaped correctly — a detail that quietly breaks codes in a lot of tools, because the code still scans, it just carries the wrong data. DESIGN THAT STILL SCANS Six module shapes, five corner frames, five corner centres, linear and radial gradients, adjustable module spacing and quiet zone, and a centre logo with a padding ring. Ten presets, every one of them covered by the project's test suite. Tap "fit the largest logo that still scans" and the app searches for the biggest logo your specific code can carry, checking each size against the decoder — not against a generic rule of thumb. EXPORT PROPERLY PNG at up to 4096 pixels, plus SVG and vector PDF that stay sharp at any print size. Every format included. A SCANNER THAT WARNS YOU Point it at a code and see exactly where it leads before anything opens. That is the answer to a sticker pasted over a real one. NO CATCH Free, with no subscription, no in-app purchases, no ads, no account and no analytics. The app makes no network requests of any kind — there is no code in it that could send your data anywhere. Your library and your logo images stay on your phone. Your codes are static, which means the content is encoded in the pattern itself. They work forever, they work offline, and nobody can switch them off, redirect them, or move them behind a paywall later. OPEN SOURCE The encoder, the scan checker and the test suite behind all of this are public at github.com/keyfive5/QR-Code-Generator QR Code is a registered trademark of Denso Wave Incorporated.

Your iPhone is measuring itself all day. DataFastView is where you get to see it. Live Wi-Fi quality, battery, CPU, memory, storage and the weather — in the Dynamic Island, on the Home Screen, in Control Center, and on one screen inside the app. Everything is measured on the device. There is no account, no tracking, and nothing to sign up for. WI-FI QUALITY, NOT SIGNAL BARS A full-bar connection with 300 ms of jitter is a bad connection, and the bars will never tell you. DataFastView scores your link from 0 to 100 using four things it measures directly: • Round-trip time to your own router • Round-trip time to the internet • Jitter — how much that time varies • Packet loss Live upload and download rates sit next to the score, and a download-speed test runs only when you tap the button. Tap "How this score is measured" to see exactly how the four are weighted. Nothing is hidden behind a marketing number. ENERGY AND SYSTEM Battery level and charging state, Low Power Mode, and thermal state — Normal, Elevated, High or Critical. CPU on a fixed 0-100% scale, so a phone idling at 3% does not draw the same mountain as one at 100%. Memory split into active, wired, compressed and free. Free storage and time since the last restart. There is no battery temperature, health or cycle count, because iOS publishes no public API for any of them. Any app showing you those is estimating. This one tells you what it actually knows. THE DYNAMIC ISLAND Choose one metric for the left side and one for the right, from CPU, memory in MB or percent, storage in GB or percent, uptime, battery, thermal state, network rates, Wi-Fi quality, or a clock that keeps ticking on its own. Every option shows its live value while you pick, so you are choosing from real numbers rather than names. WIDGETS Actions (medium) — up to ten launch buttons of your own, in two rows of five, each with a symbol or a real app icon and a colour you choose. Load a screenshot of your wallpaper and the widget reads as transparent. Storage and network (small) — a ring of used space, free and used in GB, and the last Wi-Fi reading. Weather (large) — current conditions, temperature, feels-like and the next five days, in the app's own palette. Weather data provided by Apple Weather. There are Control Center controls too, and rotating phrases on the Lock Screen. WEATHER Current conditions, the next hours and the next days, with a two-day temperature trend on the Now tab that marks every peak and trough. Location is used only to ask for the forecast where you are, and only while you are using the app. TOOLS A password generator that runs entirely on the device, using the system's cryptographic random source. Set the length and character classes, exclude look-alike characters (O 0 I l 1) and keyboard runs (abc, 123, qwe), and read the real strength in bits of entropy. Nothing is stored, nothing is sent, and the clipboard copy expires. PRIVACY No account. No analytics. No advertising. No third-party SDKs. The app has no server, so there is nowhere for your data to go. Everything you configure lives on your iPhone and disappears when you delete the app. ONE PAYMENT Buy it once. No subscription, no trial that turns into a bill, no in-app purchases. English and Spanish. iPhone only, iOS 17.6 or later.
