OPGG is the platform most League of Legends players trust for champion builds, runes, and counters. For over a decade it has been the reference site for anyone who wants to queue with a plan — the right items, the right rune setup, and a clear sense of which champions counter theirs and which they counter in return. That depth of build data, kept current with every patch, is what made OPGG the default companion for LoL players and what keeps it at the center of the game's ecosystem.
The build coverage is comprehensive. For any champion, OPGG surfaces the strongest current builds, the rune pages that match the meta, and the skill orders and item paths that win games, all drawn from real high-level play rather than theory. Counters are mapped out so you know what to pick and what to avoid, and a tier list ranks the meta so you can see at a glance which champions are overperforming. Because the data updates with each patch, the builds you follow are never stale, which is the whole point of a stats companion.
OPGG wraps the build data in features that make it usable in real time. You can search any summoner by Riot ID and tagline to see their stats and match history, watch pro spectate games to learn from the best, and ask the OP.GG AI chatbot anything you want to know about League of Legends — from how to play Kassadin in the middle role to how a pro is performing lately. The platform extends to a desktop app and mobile apps, covers Teamfight Tactics, Valorant, Overwatch 2, and many other titles, and supports more than twenty languages. For League of Legends players who want their builds, runes, and counters in one trusted place, OPGG remains the standard.

Explore AppADHD Test - a research-backed ASRS v1.1 screener with an optional AI personalized report.
ADHD Test ADHD Test shows how a focused web tool can take a respected clinical instrument and make it approachable for everyday adults. The product is built around the ASRS v1.1 screener, a six-item questionnaire co-developed by the World Health Organization and a Harvard research team, which is one of the most widely used screening measures for adult ADHD in primary care settings. From a product perspective, the build is elegantly simple: a short questionnaire flows into an instant Low, Moderate, or Elevated result, and an optional upgrade path opens an AI-generated personalized report. That report layers on real value—an executive-function pattern map, an analysis of overlapping factors such as sleep, stress, anxiety, and burnout, tailored educational strategies, and a clinician discussion guide with PDF export. The design respects the user's time and intelligence. There is no sign-up wall before the basic result, and the educational framing is consistent throughout: the tool is explicitly a self-screening aid, not a diagnosis. This kind of clear, evidence-aligned positioning is what separates a responsible health utility from a clickbait quiz. For makers browsing a showcase, ADHD Test is a strong example of a single-purpose product done well. It pairs a validated instrument with modern AI assistance in a way that genuinely extends the screener's usefulness, proving that a tight scope and good source material can produce something far more valuable than a bloated all-in-one app.

Explore AppFree PSL Rating runs entirely in your browser for an instant, private AI PSL score with no signup.
Free PSL Rating Free PSL Rating is a browser-based AI tool that analyzes a single uploaded face photo and returns an instant attractiveness estimate on the PSL 1-8 scale, with all processing happening directly in the user's browser. Unlike services that send images to a remote server, Free PSL Rating keeps everything client-side, which means no uploaded photo is ever stored, addressing one of the biggest concerns people have about face-rating tools. The result is a fast, private, and signup-free experience for anyone curious about the PSL framework. To use Free PSL Rating, a person uploads one clear, front-facing photo in JPG, PNG, or WebP format up to 10MB. AI models loaded in the browser then examine visible facial structure and photo quality, generating an overall PSL score, a tier label, and a plain-English explanation of what the number means. The tool also produces a photo confidence score that indicates how reliable the rating is based on image quality, helping users judge whether their result reflects their actual features or the limitations of the photo. Free PSL Rating stands out by breaking the single score into four meaningful categories: harmony, covering symmetry and proportions; dimorphism, reflecting sex-typical structural cues; angularity, capturing jawline, cheekbones, and facial edges; and presentation, accounting for lighting, sharpness, skin clarity, and grooming. Users also receive a shareable result card displaying their overall score, tier, and category scores. With more than 12,800 free ratings run and an average score of 5.4, the platform has built a steady community. A paid advanced report is available through PSL Scale for deeper analysis, but the free tier delivers a complete, private, and instant PSL assessment.
