$50 and the app is yours.
No subscription required. Try free for 14 days, then a single $50 payment unlocks WordSpark — plus a full year of included updates.
After that, renew your license for $50/year to keep getting updates. Or don’t. If your license lapses, you keep the version you have. No further payment required, ever.
