What Duolingo does well
Duolingo reported 58.7 million 6 daily active users and 12.7 million 6 paid subscribers in Q2 2026 6.
Streaks and a free-to-start, paid-to-continue plan. A Streak Revival event let learners restore their longest streak 6.
What changes for geography
Geography learners. GeoGuessr asks people to join 100 million 4 players (self-reported), and Seterra lists +400 5 map quizzes.
They need a daily path through countries, capitals, flags and maps, with streaks and levels, not only a Street View guess 3.
What's the crossover
From DuolingoFrom Duolingo: a daily streak and a short lesson you can finish in a sitting 6.
From geographyFrom the market: countries, capitals, flags and maps, with progress you can see 3.
A streak-based daily geography habit. GeoBingo already does this as a young indie, so the open angle is a deeper course, or a region the current quiz apps skip.
Demand check
Publish a signup page for a narrow geography path, such as US counties or African capitals, and share it in the learner groups you can reach. Count signups against visits. If almost nobody signs up, the live quizzes already cover the need.
Build plan
- Start: pick a region and a fact type, such as capitals or flags, and write a starter set of items.
- Next: ship a web app with a daily quiz, a streak counter, and a map the learner taps.
- Then: add a reminder email and a simple paid plan behind a free opening unit.
- After that: invite the signup list and fix the item where people drop off.
Copy the build prompt
Build a small web app for learning geography through a daily habit. Each lesson asks the learner to pick a country, capital or flag on a map or from a short list. Track a daily streak, show progress per unit, and send a reminder email when the learner has not practiced today. Keep the opening unit free and put later units behind a paid plan. Store users, items, streaks and plan status in a database. Use plain, accessible HTML.
