As answered by people managing Cert Decoder and Titans Grip.
Cert Decoder's answer
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Titans Grip's answer:
Titans Grip started with a simple observation: if you train boxing, you need a boxing app. If you train BJJ, you need a BJJ app. Generalist fitness apps do not cut it for technique-heavy sports. We built one app per sport, each with AI trained on the sport rules, terminology, and scoring criteria. Part of Doved Studio, an indie studio focused on vertical AI tools for niche audiences.
Cert Decoder's answer
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Titans Grip's answer:
Swift 6 with strict concurrency, SwiftUI, SwiftData, iOS 17+. Backend on Supabase (Postgres with RLS). AI video analysis uses CoreML on device combined with cloud inference. AI coach chat powered by frontier LLMs fine-tuned per sport. RevenueCat for subscriptions. TestFlight and Fastlane for CI/CD.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Titans Grip's answer:
Serious amateur through advanced athletes in combat sports (boxing, MMA, BJJ, Muay Thai, judo, wrestling, karate, taekwondo, krav maga, kickboxing, kung fu, sambo, aikido), strength sports (powerlifting, strongman, Olympic weightlifting), and fitness disciplines (CrossFit, calisthenics, bouldering, bodybuilding, Pilates). Ages 16 to 45, training 3+ times per week, often prepping for competitions or belt tests. Users who want real coaching feedback but cannot afford a private coach.
Cert Decoder's answer
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Titans Grip's answer:
Because the AI actually understands your sport. A boxing coach on FightCamp does not understand BJJ guard retention. A generalist fitness app like Freeletics does not score a sumo deadlift against IPF depth standards. Titans Grip ships a dedicated app per sport with a dedicated coach persona (Coach Marcus for boxing, Professor Leo for BJJ, Coach Pavel for powerlifting, Coach Ilya for Olympic weightlifting, Kru Somchai for Muay Thai). You get 24/7 chat, video analysis, training log, nutrition, and competition countdown built around your specific sport.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Titans Grip's answer:
Titans Grip is a suite of 23 AI coaching apps, one fully dedicated to each sport. Most competitors are either a single generalist fitness app or a boxing-only / BJJ-only product. Titans Grip goes deep on sport-specific rules (IBA, Unified Rules, IBJJF, IPF, IWF, WKF, UWW, IFMA, FIAS and more), sport-specific coach personas, and AI video analysis trained on sport-specific movements. The scoring model rates technique 0 to 100 with frame-by-frame feedback, not just reps counted.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
