## Decypher

Decypher turns an ordinary walk through a British town into a small history lesson. Point your iPhone camera at a post box or other piece of street furniture, and the app uses AI-based recognition to identify the object and explain the royal cypher stamped onto it. Because each cypher corresponds to a reigning monarch and an era, those small marks become a readable timeline of the streets around you.

Beyond simple identification, Decypher explains the design language behind the objects: the shapes, the lettering, the regional variations and the manufacturing history. It was designed to be usable while you are actually out exploring, with a simple onboarding flow and clear on-screen explanations, and reviewers have noted that it runs smoothly even on older iPhones such as the XS.

The app requires iOS 16 or later and is currently listed only for iPhone. It is free to download, aimed at curious walkers, history enthusiasts and anyone who wants to understand the everyday objects they pass without noticing.

**Pricing & Plans:** Free to download from the App Store, with no in-app purchase tiers advertised on the listing.

- **AI camera recognition:** Point your iPhone at a post box or piece of street furniture and let the app identify the object in front of you.
- **Royal cypher decoding:** Learn which monarch each cypher represents and what it tells you about the age and origin of the item.
- **History and design context:** Get explanations of shapes, lettering and manufacturing details that make UK street furniture distinctive.
- **Built for exploring on foot:** A lightweight interface designed to be used outdoors while walking, with clear onboarding and instructions.

**Strengths:** Free to download with no obvious paywall on the main feature; Simple, well-reviewed interface that runs well on older iPhones; Turns ordinary walks into an educational, curiosity-driven activity

**Limitations:** Currently limited to iPhone and requires iOS 16 or later; Focused on UK street furniture, so its value is limited outside the UK; Last version update was in 2023, so the feature set is relatively static

## Gauth

Gauth is a study app that turns homework problems into teaching moments. A student photographs a question or pastes it into the web calculator, and the AI returns a structured solution that walks through the reasoning instead of just giving the final number. Coverage is deliberately broad: maths and calculus, statistics, physics, chemistry, biology, economics, literature, business, writing, social science and general-purpose subjects, which makes it useful across very different curricula rather than only for algebra drills.

The platform pairs two layers of help. The AI layer answers quickly and free of charge for a limited number of questions, with detailed step-by-step explanations and tips on the concepts behind each step. On top of that sits a tutor service that connects students to real verified tutors around the clock; the company advertises tens of thousands of experts, high satisfaction rates, fast turnaround on hard problems and access to a large question knowledge base. Gauth also offers an Academy section with courses and a newer Gauth Atlas experience that turns subjects into explorable visual maps grounded in cited sources.

Gauth is available on the web and as a mobile app on both iOS and Android, where it has a large review base. It follows a freemium model: a free tier covers everyday questions, while Gauth AI Pro unlocks unlimited answers and premium features via a free trial followed by a paid subscription. Exact plan prices and trial conditions should be confirmed on the official site.

**Pricing & Plans:** Freemium. A free tier answers a limited number of questions, and Gauth AI Pro offers unlimited answers and premium features, typically starting with a free trial before a paid subscription. Check the official site for current prices and trial terms.

- **Photo-based question solving:** Upload or paste a homework question and receive an answer in seconds, covering maths, sciences, business, writing and social sciences.
- **Step-by-step explanations:** Solutions break the problem into clear steps with reasoning and conceptual tips, so students learn the method rather than only the result.
- **24/7 human tutor service:** When AI output is not enough, students can escalate to verified human tutors for personalised guidance, including help with advanced problems.
- **Gauth Atlas visual learning:** An explorable visual map turns a subject into zoomable layers of related ideas, with each image traced back to a real source.
- **Cross-platform access:** Use Gauth in the browser or through the iOS and Android apps, with an Academy area for structured courses and a large study-resource library.

**Strengths:** Works across a very wide range of subjects, not just mathematics; Step-by-step explanations focus on understanding rather than answer copying; Human tutors are available around the clock for problems the AI cannot resolve; Free tier plus mobile apps on iOS and Android make it easy to try

**Limitations:** Unlimited answers and premium features require the paid Gauth AI Pro subscription; AI-generated solutions can still contain mistakes on unusual or ambiguous problems, so they should be checked; Reliance on instant answers can undermine learning if used without attempting the problem first
