TigerText is the easiest way to add alt text to photos on iPhone — and it's now completely free. Point it at any photo and TigerText writes a clear, accurate description of what's in it. The description is saved into the photo's own metadata, so it travels with the image when you post or send it. Mastodon, Bluesky, and any other app that reads standard image metadata will pick it up automatically. Everything happens on your iPhone. No internet connection. No account. No ads. No tracking. WHY ALT TEXT MATTERS Alt text is how a photo becomes readable to someone using a screen reader. Without it, an image is just "photo" — no content, no context. Writing it by hand for every picture is real work, and that's why so many images go undescribed. TigerText does the first draft in seconds so you can post with a description instead of without one. FULLY OFFLINE, GENUINELY PRIVATE TigerText runs a vision-language AI model that ships inside the app. Your photos are never uploaded, never sent to a server, and never seen by anyone but you. It works on a plane, in a basement, or with your phone in airplane mode — because there's nothing to connect to. Privacy here isn't a policy promise. It's how the app is built. There is no server to trust, because there is no server. BUILT WITH THE COMMUNITY IT SERVES TigerText was shaped by feedback from blind and low-vision users, and it's designed to be used entirely with VoiceOver — not merely to pass an accessibility checklist. Every control is labeled, every action is announced, and the whole flow works without ever needing to see the screen. That includes the parts people usually forget: you can hear the description read aloud before you save it, edit any wording you disagree with, and know immediately whether a photo already has alt text. WHAT YOU CAN DO • Describe any photo in your library, one at a time or in batches • Hear any description read aloud before you commit to it • Edit the wording — it's your description, the AI just drafts it • See at a glance which photos already have alt text and which don't • Add descriptions to animated GIFs without losing the animation • Send photos straight from the Photos share sheet • Share a photo with the description already embedded FREE, AND STAYING THAT WAY Every feature is free forever. There is no paid tier, no subscription, no in-app purchase, no locked content, and no ads. TigerText uses the Qwen2-VL model (Apache 2.0) running through Apple's MLX framework. The bundled model is verified with a SHA-256 integrity check on every new version, so you always run the genuine, untampered model. A NOTE ON THE DOWNLOAD SIZE TigerText is a big download, and that is the whole point. The entire AI model lives inside the app instead of on a server somewhere. Nothing is streamed, nothing is fetched, and none of the work happens on someone else's computer. Download it once and it works forever. On a plane. In a tunnel. In a basement with no signal. On a trip with no data plan. There is no server to go down, no API to get shut off, no subscription to lapse, and no spinner while something uploads. Your photos are never part of anybody's dataset, because they never leave your phone. Most apps that describe images send your pictures away to do it. TigerText carries the whole thing with you instead. That's what makes TigerText a true offline utility: the big download is the feature. Install it once over Wi-Fi, and describing a photo never needs a network again.
QR Forge

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.

Verdict
The clearest difference is iOS requirement: QR Forge at 16.4 against TigerText's 18.2. On price, ads, in-app purchases and device support there is nothing between them.
