Think Math is a concept explorer that lays out every math concept from elementary through high school on a single map. 802 concepts cover the whole curriculum, from counting to calculus. Narrow things down in three steps - area, unit, concept - to find what you need fast. Fractions, roots, exponents and sigma notation are typeset properly, just like a textbook. Concepts are linked to short YouTube concept videos, so you can read an idea and then watch it. KEY FEATURES * 802 concepts across elementary, middle and high school * Three-step navigation: area > unit > concept * Textbook-quality math typesetting (fractions, roots, exponents, sigma) * 700+ English concept videos, linked concept by concept (more added over time) * Explanations and examples written at each grade's level * Concept cards with Basic and Advanced views * Listen and learn: hear any concept read aloud * Wrong-Answer Notes (save photos, handwriting and formulas) * Summit hall - enrichment math beyond the curriculum * Study streaks and daily reminders * In English and Korean - switch any time from the home screen * Layouts for iPhone and iPad (iPad works in portrait and landscape) GREAT FOR * Students who want to see how units connect in the big picture * Test-takers who want a fast concept review * Parents who want to see how math builds grade by grade * Teachers who need a concept map for class * Math lovers who enjoy thinking through proofs and formulas PRIVACY AND USE * No sign-up needed - just open and start. * All study data stays on your device and is never sent to a server. * Ads are shown to keep the app free (Google AdMob). An optional one-time Pro purchase removes ads. * On first launch, iOS asks whether to allow tracking. You can decline and still use every feature.

글벼림은 내 작품 한 편을 끝내기 위한 앱입니다. 장르에 맞는 뼈대를 따라 쓰고, 다 쓴 글은 다듬고, 여러 편은 묶어 하나의 작품으로 만듭니다. 근대문학 명문장 해부는 그 곁을 받치는 본보기입니다. [내 글 — 뼈대를 채우며 쓰기] 자유·에세이·단편·시. 장르마다 뼈대가 있어요. 에세이는 여는 장면에서 시작해 떠오른 생각, 파고들기, 뒤집기, 닫기로. 칸마다 무엇을 쓰는 자리인지 안내가 붙고, 같은 갈래 명문의 첫 문장도 바로 볼 수 있어요. [다듬기 — 규칙으로 짚어주기] 쓴 글에서 번역투("~에 의해", "되어졌다"), 관공서 말투, 확신을 흐리는 군말, 너무 긴 문장을 찾아 표시해요. 채점하지 않습니다. 표시는 힌트일 뿐, 다듬을지는 쓰는 사람이 정해요. [완성작 — 여러 편을 한 작품으로] 완성한 글이 쌓입니다. 시는 한 편이 그대로 한 작품이고, 소설처럼 여러 장이 모이는 글은 편을 묶어 하나의 작품으로 만들어요. 순서를 바꾸고, 이어 쓰고, 통째로 내보낼 수 있습니다. [읽기 — 명문장 해부] 현진건·김소월·이상·정지용·김유정 등 근대문학 88편. 어느 말에 어떤 기법(은유·대조·의인화·감각어·리듬)이 걸렸는지 문장에 직접 밑줄을 긋고 풀어드려요. [벼리기 — 문장 다듬기 연습] 일부러 못 쓴 문장을 직접 다듬는 405개의 연습. 중복 덜기, 번역투 걷기, 피동을 능동으로, 압축, 문장 쪼개기 등 8가지 기법. 다듬으면 그 자리에서 결과를 알려줘요. [성장 — 쌓이는 기록] 완성한 글, 기법별 정확도, 연속 학습, 칭호(습작생에서 문장의 대가까지). 오늘 목표를 정하고 매일 한 문장씩. [이런 분께] · 블로그·에세이·업무 글을 더 잘 쓰고 싶은 분 · 쓰다 만 글을 끝까지 완성하고 싶은 분 · 문장력을 기초부터 다지고 싶은 분 · 계정 없이 조용히 쓰고 싶은 분 글쓰기와 연습은 인터넷 없이 동작합니다. 원고와 학습 기록은 이용자 기기에만 저장됩니다. 연습 화면에는 광고가 나옵니다. 맞춤형 광고는 쓰지 않으며, 앱 안에서 한 번 구매하면 광고를 없앨 수 있어요. 수록된 문학 작품은 저작권 보호기간이 끝난 근대문학(저자 사망 후 70년 경과)만 사용했습니다.

Verdict

The call

The clearest difference is in-app purchases: Think Math at none against 글벼림's 1. Think Math also leads on iOS requirement (13.0 vs 15.0). 글벼림's advantage is update cadence (weekly vs every 3 weeks). On price, ads and device support there is nothing between them.
