4thewords vs Habitica

4thewords is a writing-specific gamification tool that ties word counts directly to monster battles, with a subscription cost of $96–$144 per year. Habitica is a general-purpose habit and to-do gamification app with RPG elements, available as a freemium model. The main difference is focus: 4thewords is specialized for authors who want a writing-only environment, while Habitica offers broader life management. Pricing also distinguishes them, with 4thewords requiring a paid subscription and Habitica offering a free tier.
