A little Thai, every day. NexaThai helps you connect Thai letters, sounds and meaning. Follow guided lessons, practise handwriting and revisit familiar material with review informed by your progress. LEARN THE SCRIPT Explore Thai consonants, vowels, tone marks and numbers. Build from characters to syllables and useful words through short, guided activities. WRITE TO REMEMBER Watch animated stroke guides, trace and copy characters, then write from memory. Choose specific characters for focused practice or explore at your own pace. CONNECT SOUND AND MEANING Practise listening, recognition and reading alongside writing. Use mixed practice, flashcards and your own study lists to revisit what needs attention. TRY A GUIDED CONVERSATION Listen to a short exchange at a Thai drink stall, reveal the meanings and practise your reply. Speaking features depend on supported device capabilities and are practice aids, not a pronunciation assessment. CONTINUE AT YOUR OWN PACE Return to your saved place, review familiar material and gradually meet new content. Designed for iPhone and iPad. Core learning is free and does not require an account. An optional monthly NexaThai Pro subscription enables supported progress and custom study-list sync across your signed-in devices.

Preplexity is a complete study companion for IT certification exams. One app, 32 certifications across 7 vendors: CompTIA, AWS, Microsoft Azure, Cisco, Google Cloud, ISC2, and ISACA. From A+, Network+, and Security+ to CCNA, AWS Solutions Architect, AZ-104, CISSP, CISM, and CRISC, if it's on your certification path, it's here. A STUDY PLAN FOR YOUR EXAM DATE Set your exam date and get a daily plan sized to the days you have left: what to read, what to practice and when to take a full simulator exam. The plan moves through Learn, Practice, Simulate and Review, today's tasks show on Home, on Progress and on the course page, and a daily reminder keeps you on track. DAILY CHALLENGE Five fresh questions from your course every day, done in about two minutes. Finish it for bonus XP and come back tomorrow for a new set. PICK UP WHERE YOU LEFT OFF Home opens on what you were doing last: the practice session, flashcard deck, study topic or exam you left, one tap away. OVER 10,000 QUESTIONS, EVERY ONE EXPLAINED Each question comes with a clear explanation of the correct answer and why every wrong answer is wrong. Answer choices are shuffled and balanced so you learn the material, not the option positions. EXAM SIMULATOR Timed, full-length practice exams that mirror the real thing. Question counts, time limits, passing scores, and domain weightings are modeled on each certification's official exam guide. Finish with a pass or fail verdict, a per-domain score report, and for ISACA exams an estimated scaled score. PRACTICE MODE Untimed practice with instant feedback. Weak areas are resurfaced automatically so you review what you miss, and you can report any question from inside the session. SMART FLASHCARDS More than 3,000 spaced-repetition flashcards. Rate each card Again, Hard, or Easy and the deck reschedules itself around what you find difficult. STUDY MATERIALS AND DIAGRAMS Nearly 1,200 concise study topics organized by exam domain, with native diagrams for every certification: process flows, hierarchies, lifecycles, and comparisons built for your phone, not scanned PDFs. READINESS SCORE A per-course readiness score blends your practice results, simulator performance, and study completion, weighted by each exam's official domain percentages, so you know when to book the exam. TRACK YOUR PROGRESS Per-domain mastery, streaks, XP, badges, exam history, and an Activity calendar with a breakdown of every study day show exactly where you stand and what to study next.
