Built by AityTech in Japan.
StudyKits is an independent project from AityTech (AI Typhoon Tech) — a 個人事業主 (sole-proprietorship) studio in Japan, founded in 2022.
From the manufacturing floor to the App Store
AityTech (AI Typhoon Tech) is an indie 個人事業主 (Kojin Jigyou Nushi — sole-proprietorship) studio based in Japan, founded in 2022. The "AI Typhoon" comes from a decade spent on the manufacturing floor — making excavator parts for Hitachi, Sumitomo, Komatsu, and Mitsubishi — combined with modern AI and software development. The studio ships factory digital-transformation tools, AI visual-inspection systems, and consumer-facing apps.
StudyKits is the consumer line: native iOS, iPadOS, and macOS apps for cloud and project-management certifications. It started after preparing for AWS certifications first-hand and finding that every existing study app either farmed real exam questions (against the policy of every cert body), buried the learning under banner ads, or charged a recurring SaaS fee that punished slow studying. StudyKits is the response — built on the official exam blueprint, one-time IAP pricing per cert, fully offline, with FSRS spaced repetition instead of question-dump memorisation.
Each StudyKits app is built around the issuing body's published exam guide, never scraped from forums. Questions are written from scratch, mapped to the official domains, and reviewed against the AWS / Google Cloud / PMI source material before shipping. The apps stay native to Apple platforms because that's the audience that values privacy, offline access, and one-time purchase pricing — and because Apple's accessibility primitives (Dynamic Type, VoiceOver, Smart Invert) ship for free with the platform.

The short version
I studied for the AWS certifications myself and bounced between apps that were either expensive subscriptions, ad-funded clones, or browser-only. None of them were a great fit for studying on the train, the way I actually study.
StudyKits is an attempt at the simplest possible answer: native Apple apps with the official exam blueprint, fair pricing, and no tracking. Each certification is its own app. You pay $3.99 once for the full bank, or use the free tier for as long as you like.
I am building it slowly and honestly. There are no inflated stats on this site, no fake testimonials, no invented user counts. If you find a bug, an outdated question, or a typo — email me at support@studykits.app.
Operating principles
No subscriptions, ever.
Pro is a one-time $3.99 in-app purchase per certification. You buy it once. You own it. You get updates for free.
Offline-first.
Every question, every explanation, every flashcard ships with the app. No background sync, no telemetry, no required login.
Honest copy only.
Until we have audited Apple App Store ratings, you will not see star ratings on this site. Until we have measurable pass rates, you will not see pass-rate claims. No inflated download counts, no invented testimonials. Trust is built slowly.
Independent.
StudyKits is not affiliated with AWS, Google Cloud, Microsoft, or PMI. The exam names and trademarks are owned by their respective providers.
