CashSDKCashSDK
For productivity apps

Monetize the upgrade, the seat, and the unlock.

Productivity apps charge three ways — a freemium Pro subscription like Notion Plus or Bear Pro, per-seat team plans billed per member, and the pay-once unlock that indie apps like Things still sell. CashSDK ships all three from one integration, with paywalls you A/B over the air and revenue you can read the same afternoon you launch.

Pro subscriptions · per-seat teams · one-time unlocks — one SDK, both stores.

How the category prices

Three revenue models, from free to forever.

The top productivity apps stack a freemium Pro subscription, a per-seat team tier, and — for the indie holdouts — a one-time pay-once unlock. Here is how the category really charges.

Recurring

Pro subscription

The dominant pattern: a permanent free tier hooks the user, then an individual Pro plan unlocks sync, history, and AI. Annual billing discounts monthly ~15–35%.

  • Notion Plus ~$10/mo (annual); Todoist Pro ~$4/mo
  • Bear Pro $2.99/mo or $29.99/yr; Ulysses $5.99/mo, $49.99/yr
  • Fantastical Individual from ~$4.75/mo billed annually
  • Free tier gates sync, version history, offline & AI

Per-seat

Team & business plans

A higher tier billed per active member, adding admin, SSO, and the shared workspace. Per-seat scales linearly; Enterprise is contact-sales with volume discounts.

  • Notion Business ~$20/seat/mo; Todoist Business $8/seat (annual)
  • 1Password Business $8.99/seat; Teams flat $24.95 for 10
  • Grammarly Pro $12/seat (annual); Superhuman $30–40/seat
  • Gates SSO, roles, audit log, priority support

One-time

Pay-once unlock

The indie/Apple-native holdout: buy the app once and own it, usually sold per platform with sync left free. Most of the category has migrated away from it toward recurring revenue.

  • Things 3: Mac $49.99, iPad $19.99, iPhone $9.99 — one-time
  • Sold per platform; Things Cloud sync stays free
  • No subscription — you keep the version you buy
  • Ulysses left one-time for subscription in 2017 (the shift)

Things · (historically Ulysses)

Market context only. Prices are representative US list prices for 2025–26 and vary by region, promotion, login state, and billing term (annual plans discount the monthly rate); app and tier names are trademarks of their owners and are cited to describe the category, not affiliation. On the stores, these apps file under the Apple App Store and Google Play “Productivity” categories.
