Spaced Repetition System for memorizing capitals/flags/country positions

I have a pub trivia team and like to play geogussr, sporcle, worldle. I wanted to see if there was a way to memorize all of the country capitals and flags. I look online and find the Anki community and find they are maintaining a deck for exactly this. In about a month with ~15 mins a day or so, I learnt all of the capitals and flags.

痛点：Anki 这类间隔重复工具学习曲线陡、必须用桌面端加卡，想把「背国家首都/国旗/地理位置」这种轻量知识塞进去的休闲用户被挡在门外。

目标用户：酒吧问答/trivia 队伍成员、GeoGuessr、Sporcle、Worldle 等地理游戏玩家，以及想快速背地理常识的休闲学习者。

证据：they found the learning curve of Anki too hard. So, I built a webapp that lets you use the spaced repetition system with the deck already added. Mobile friendly in browser to fix the pain point of needing a desktop to add Anki cards. / Right now, I'm just playing around with learning how to get users, before I actually try to make any money off of a project.

变现：免费基础牌组+订阅解锁更多牌组（化学元素、世界历史、GRE 词汇等）与进度统计；或一次性买断去广告；也可做 trivia 队伍的团队版/赛事练习包。

MVP：用 Next.js + Supabase 做单页应用：内置 1-2 个预制牌组（首都+国旗），手机浏览器可用的 SRS 复习界面（SM-2 简化算法），无需注册即可练习，邮箱保存进度，两周内可上线，先验证留存而非收费。

竞品：Anki、Seterra、Sporcle、Quizlet、JetPunk、Worldle/GeoGuessr（同类场景但非 SRS）

摘要：开发者因队友觉得 Anki 太难上手，做了一个内置牌组、移动端友好的地理间隔重复学习 webapp（geo.connormdk.xyz），约 15 分钟/天一个月可背完所有国家首都与国旗，维持只需 5-10 秒/天。目前完全免费、限 500 名用户，作者明确说还在摸索获客、尚未考虑变现。痛点真实但用户为休闲地理爱好者，付费意愿与竞争空间都有限。
