19 Theory turns a goal into a plan you can follow, fitted to the week you actually have. Someone who teaches builds the curriculum. 19 Theory turns it into your week, and hands you one thing to start today. WHAT IT DOES • Structured plans — week-by-week or day-by-day curricula published by schools, coaching centres and training institutes. Every section is reviewed by a person before a learner can reach it. • One timetable — several plans, one schedule. Say how many hours you have, or name a date to finish by, and the week is built around it. Work that will not fit moves to the next week; it is never dropped. • Today — a queue in time order. Late work first, then what is due, then a way to get ahead, with one thing pulled out to begin. • Modules and quizzes — reading, practice questions and training runs. Keep your place across sessions, and earn a certificate on the ones that offer it. • Study reminders — one notification a day, at a time you choose, naming the day's work. • Up to six learners on one login — for a family, each with their own plans, progress and timetable. FOR TEACHERS AND COMMUNITIES • Publish your own plan, or adopt one another community has already published. • Assign it to a whole group in one action, and set the date the cohort is working to. • See who is behind — per plan and per learner — and coach them through it. WHAT IT WILL NOT DO • It will not guess your pace. Set no weekly hours and it says "your own pace" and counts modules, rather than printing a percentage it cannot stand behind. The plan still runs. • It will not grade your character. No streaks, no scores, no badges. Late work is listed as late and then rescheduled, which is the only useful thing to do with it. • It will not invent a curriculum for you. Plans come from people who teach. AI helps them draft; nothing reaches a learner until a person has reviewed every section of it. Browse plans, modules and quizzes, and read a full curriculum, without an account. An account is only for the part that is yours: your timetable, your progress and your reminders. Questions or feedback: nextgenapps146@gmail.com

Verdict
The clearest difference is rating: 19 Theory at 4.8 against vPro's 1.0. 19 Theory also leads on update cadence (every 6 days vs every 2 months) and ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
