WayFinder vs Calcanto

WayFinder is a voice-first visual assistant for blind and low-vision people. Press the microphone, ask a question aloud, and WayFinder takes one photo and speaks an AI-generated description. Ask about objects, text, colors, or the general scene in front of the camera. HOW IT WORKS • Sign in with Apple, with Google, or with an email address and password. Nothing else is asked of you. • Press the microphone to speak. That is the only way WayFinder listens — there is no wake word and no background listening. • You choose whether to send camera images for third-party AI processing. Until you agree, no image is sent. You can change the decision in Settings. • Each request uses one still photo. WayFinder does not record video. • Speech recognition runs on the iPhone. Raw microphone audio is not sent to WayFinder. • Answers and important status messages are spoken aloud. Controls have VoiceOver labels, large touch targets, and scalable text. SAFETY LIMITS AI can miss, misidentify, or misread things. If WayFinder cannot produce a sufficiently grounded answer, or if the camera, network, account, server, or AI provider fails, it tells you to stop instead of presenting the failure as a clear path. WayFinder is assistive information only. It is not a mobility aid or a medical device. It does not replace a white cane, guide dog, your own judgment, or orientation-and-mobility training. Never rely on it to decide whether to step or cross. USAGE LIMIT Each authenticated account receives exactly 25 lifetime successful vision analyses. Request 26 and later is refused before any AI request is made. There is no subscription, payment, purchase, upgrade, or quota reset. PRIVACY AND CONTROL The requested photo is sent over an encrypted connection to the WayFinder server and processed by a Google Gemini model on Google Cloud Vertex AI. WayFinder does not store the raw image. Questions, answers, and any answer report you submit are retained for up to 30 days for history and service operation. You can erase history or delete your account in the app. LANGUAGES The interface and spoken flow support English and Russian.

Calcanto is a calculator that says its results out loud, changes its look, and gets the arithmetic right. 0.1 + 0.2 = 0.3 The basic engine works in Decimal rather than binary floating point, so that sum comes out as 0.3 and not 0.30000000000000004. Results carry 15 significant digits, rounded half-up. IT SPEAKS, IN TWO LANGUAGES A female and a male voice. Each language reads a number the way that language does: 120 is "one hundred twenty" in English and 一百二十 in Chinese, never a digit-by-digit spell-out. Keys are announced as you press them and the whole result is read at the end. Every clip ships inside the app and is stitched together on the device, so the readout works in Airplane mode with nothing sent anywhere. Press = and a string is plucked. Each theme has its own pluck, and it is a separate switch from the spoken readout — turn narration off and the pluck is still there. FIVE THEMES, SWITCHED WHILE YOU WATCH Onyx, Seaglass, Bubblegum, Titanium and Neon Noir. All five are in the app. None is behind a purchase and there is no theme store to visit. Changing the theme changes the sound of = with it. THREE MODES Basic — four operations, percent, sign, decimal point, backspace, clear. Multiplication binds before addition, and pressing = again repeats the last operation. Scientific — sin, cos, tan and their inverses, the hyperbolic set and theirs, ln, log₁₀, x^y and the y-th root, x², x³, √, ³√, x!, 1/x, e^x, 10^x, EE, Rand, π, e, parentheses, mc / m+ / m− / mr, 2nd, and a Rad / Deg switch. Convert — five categories. Currency covers nine: USD, CNY, EUR, JPY, GBP, HKD, KRW, AUD and CAD, on live rates labelled with when they were fetched. Length, weight, temperature and area never need a network at all. HISTORY YOU CAN PUT BACK Expression, result, time and mode are all kept. Tap an entry and it drops straight back into the input. Delete one, or clear the lot. ACCESSIBILITY, NOT AN ACCESSIBILITY MODE Every key carries a VoiceOver label written to be heard rather than read: "+" is announced as "plus", and a toggled key says which way it is currently set. Dynamic Type scales the display and the keypad as far as a fixed grid can take them, while Settings, History and the sheets keep the full range. When a key fills with its theme's accent colour, the label colour is re-picked at runtime so it stays readable. ENGLISH AND CHINESE, SWITCHED INSIDE THE APP Settings → Language applies at once, with no restart. It is independent of the system language, and independent of which language the readout speaks — an English interface reading its results in Chinese is a legitimate combination. WHAT IT DOES NOT DO No account, no sign-in, no ads, no subscription, no analytics or advertising SDK — there is no third-party SDK in it at all. History, theme and voice settings stay on your device and sync nowhere. The app makes exactly one kind of network request, for exchange rates; never open Convert and it never goes online. Free, with no in-app purchase. iOS and iPadOS 17 or later, macOS 14 or later — one download covers all three.
