漢字スイスイ

"Kanji Suisui" is an app that allows you to learn all 1026 kanji characters from elementary school grades 1-6 at your own pace, in line with the textbook's progression. — Why focus on "recalling"? — The moment when you stumble during writing practice is when you start simply "tracing the example." This app includes a few seconds' delay before displaying the example, encouraging you to first "recall" the character from memory. — Main Features — • Supports all 1026 kanji characters from elementary school grades 1-6 (in order of assignment according to the textbook's progression) • "Review" mode (Pro) — Allows you to review kanji from grades below your current grade level across grades • Forgetting curve-based system (SRS) that shows characters you're about to forget. The more you've memorized a character, the wider the gap becomes, and only characters you're about to forget will appear. • Step-by-step hints — The example is displayed stroke by stroke after an 8-second wait. We incorporated thinking time into the design. • Stroke order animation — Compliant with the official stroke order data of the KanjiVG project. • Contextualization with short example sentences and illustrations drawn for each character — All are original sentences reviewed and proofread at home, and AI-generated images. • Egg → Fluffy Dragon Growth Metaphor — As the number of characters learned, the egg cracks, hatches, and grows in 5 stages. • Multi-profile (Pro from the second child) — Siblings can have their own progress and monsters on one device. • Two-stage lock in parent mode — Math Challenge (always) + PIN/recovery code (optional) + Face ID/Touch ID for peace of mind, preventing children from changing settings. • Share progress with family — You can send "Today / This Week / All" learning status to the family chat. • No Hint Correct Answer Badge — An effect that shows "I wrote it without using hints!" • Zero ads on the child's screen — Video ads (rewarded ads) only when selected by the parent. You can watch a video ad and unlock all kanji and picture card cards for your grade level for that day only. • No personally identifiable information is collected — only aggregate usage statistics are used (no advertising IDs are used). ― What you can do for free / What you can do with Pro ― • Even with the free version, you can use the first 40 characters of each grade level. Kanji practice is continuous with a system that brings up forgotten characters (SRS) and hint delays. No payment is required to continue daily learning (only one child profile). • You can try all features for 7 days after installation. • With Pro (one-time purchase), you can use all 1026 characters from grades 1-6, review mode, all picture card cards, and unlimited child profiles. One purchase for perpetual use (no automatic renewal). • By watching one video ad beyond the parent gate, you can unlock all kanji and picture card cards for your grade level for that day only. ― For Children and Parents Who: ― * Want to learn kanji from textbooks in the order they appear in the textbook. * Want to efficiently reinforce characters that are difficult to remember even after repeated writing. * Want a relaxed approach to handwriting assessment, allowing for easy self-reflection. * Want to occasionally review kanji learned in grades 1-4, even in 5th and 6th grade. * Want parents to quickly check progress. ― Background of Development ― This app was created by a parent (individual developer) for elementary school children. We use it daily as a family, adjusting the hint delay and example sentences based on children's feedback. While referencing the best aspects of commercially available apps, we adopted a strategy combining hint delay and the forgetting curve, based on the idea that "recalling is necessary for handwriting retention." ― Credits ― • Stroke order data: KanjiVG Project (CC BY-SA 3.0) • Reading data: EDRDG / KanjiDic2 (CC BY-SA 3.0/4.0) • Allocation: Ministry of Education, Culture, Sports, Science and Technology "Grade-Specific Kanji Allocation Table" (Factual Information) For details, please see "For Parents" → "About this App" within the app. ― Future Plans ― • Further proofreading and replacement of example sentences ― Inquiries ― If you find any bugs or example sentences that are difficult to read, please let us know via the support URL. We are continuously working to improve it at home.
