Substation Engineer Suite vs Setenta

Substation Engineer Suite is the complete professional reference and learning suite for high-voltage power substation design — a fully interactive 3D substation, an extensive engineering drawing library, IEEE/NFPA references, and a full set of field calculators, all in one app. Whether you're a power engineer reviewing a single-line diagram, a student learning how a substation actually works, or a field technician who needs a fast calculation on site, SubstationEngineer puts substation knowledge in your pocket — and it works completely offline. The app is organized into two modules. Buy only what you need, or get both in a discounted bundle. ELECTRICAL SUBSTATION TOOLKIT • 160+ professional engineering illustrations across 10 categories • Pinch-to-zoom with smooth swipe navigation • Favorites and personal notes on any drawing • Full-text search across the entire library • 10 engineering calculators (transformer sizing, fault current, grounding, and more) • IEEE / NFPA reference library • 30-question knowledge quiz 3D EXPLORER • Interactive 3D substation model with 54 tappable components • Tap any component for its code reference and engineering notes • X-Ray and Energize visualization modes • 8 filterable equipment systems • 15 engineering calculators (IEEE 80 grounding, fault, transformer, and more) • Learning Hub: quiz, glossary, guided tour, and fault simulator • Substation image gallery WHY YOU'LL USE IT • Works 100% offline — no account and no internet connection required • One-time purchases — no subscriptions, ever • Buy a single module or unlock everything with the bundle • Grounded in IEEE and NFPA engineering standards • Built for real engineering work, from the classroom to the control house From study to substation, SubstationEngineer is the reference you'll actually keep on your phone. IEEE and NFPA are trademarks of their respective owners. This app is an independent reference and study aid and is not affiliated with, endorsed by, or sponsored by IEEE or NFPA.

Numbers are the part of a new language that goes by too fast. You know them on paper, and then somebody says a price or a phone number out loud and it is gone before you have caught the first half. Setenta trains exactly that. It says a number aloud and you type what you heard. A round is ten numbers; get one wrong and it shows you what you typed beside what it said, and lets you hear it again. WHAT IT SAYS Numbers on their own, prices, times, dates, years and phone numbers, each written the way that country writes it: cents after the comma or the point, the day before the month or after it. TEN LANGUAGES Spanish (Spain or Mexico), Portuguese (Brazil or Portugal), Italian, French (France or Quebec), English (United States or United Kingdom), German (Germany or Austria), Catalan, Chinese (Mandarin, mainland China or Taiwan), Japanese and Korean. The app itself is in nineteen languages. AT YOUR PACE Play a number again, or play it slower. Ask for a hint and it shows the next key to press. Each kind of number levels up on its own as you get it right, and Progress keeps your streak and how you are doing with each kind. PRIVATE BY DESIGN Setenta collects no data. There is no account and no sign-in, it works offline, and your settings and progress stay on your device. PLEASE NOTE Every exercise is a number spoken aloud, so Setenta needs sound and does not work for deaf people. It speaks with your device's own voices; if one is missing, the app's "No sound?" button says how to add it.
