MEE — Electrical Measurements

Electrical measurements, learned a few minutes at a time.

MEE breaks the university subject "Electrical and Electronic Measurements" into short lessons: a handful of questions, an explanation right after each answer, and a map that shows how far you have come. Built for students, and for anyone who wants to understand how electrical quantities are actually measured.

What makes it different from an ordinary quiz

• The figures are drawn by the app itself, from each exercise's own data: analogue instruments with a pointer and a dial, oscilloscope screens, measuring bridges, wattmeter connection diagrams, operational-amplifier circuits, instrument transformers. No scanned pictures — the drawing stays sharp on any screen and in either theme.
• Formulas are typeset in native MathML: real fractions, radicals that span the whole expression, true subscripts and superscripts.
• Mistakes come back for review, at intervals that stretch as you master them.
• Bilingual, Romanian and English: every prompt, option, hint and explanation exists in both languages, and one button switches between them at any moment.

What is inside

• 15 modules, from quantities and units to power and energy measurement
• 49 lessons and more than 300 exercises: single choice, multiple choice, true/false, and numeric answers with tolerance
• a theory recap for every module, one tap away
• a searchable formula sheet, with the whole course's formulas and definitions in one place
• a timed mock exam, with a full review at the end
• a virtual lab: 24 instruments and accessories on three benches, bought with the points you earn — voltmeters, an oscilloscope, an LCR bridge, a function generator, a data-acquisition system
• Study Mode: no hearts and no limit, for practising without the pressure
• two themes, dark and light
• daily streak, daily goal, quests and achievements, for when you need a reason to come back

No account, no server, no ads

• works offline after the first launch
• asks for no access to your camera, microphone, location or contacts
• collects, transmits and shares no data of any kind — your progress stays on your phone
• no advertising and no in-app purchases; lab points are earned only by learning inside the app
• you can save your progress to a file and load it back
