For learning apps
Monetize the habit, the streak, and the upgrade.
Learning apps run the freemium playbook — a generous free tier like Duolingo’s, a Super subscription that removes ads and limits, a family plan, and consumable streak freezes bought the moment a streak is at risk. CashSDK ships all of it from one integration, with annual plans and 7-day trials honored natively and revenue you can read the same afternoon you launch.
Freemium subscriptions · annual plans & trials · consumable power-ups — one SDK, both stores.

How the category prices
Freemium at the top, an annual plan in the middle, power-ups at the peak.
The top learning apps build a habit for free, convert it to an annual subscription behind a 7-day trial, and monetize the gamification loop with consumable streak freezes. Here is how the category really charges.
Freemium → subscription
The Super unlock
A generous free tier hooks the habit, then a single premium plan removes the friction — ads, limits, and the hearts that block a lesson after a mistake.
- Duolingo free gates lessons on a hearts/energy system
- Super Duolingo (~$12.99/mo) removes ads + unlimited hearts
- Duolingo Max (~$29.99/mo) adds AI Video Call & Roleplay
- Elevate, Quizlet, Photomath all gate advanced features behind Premium

Annual-heavy plans
Yearly, with a 7-day trial
The category steers hard to annual — often ~50% cheaper than monthly — behind a 7-day free trial. Several apps have dropped the one-month plan entirely.
- Blinkist ~$99.99/yr vs ~$15.99/mo (~50% off)
- Quizlet Plus ~$35.99/yr (~62% off monthly)
- Brilliant ~$161.88/yr; Coursera Plus ~$399/yr
- Babbel sells 3/6/12-month terms + a Lifetime plan

Consumables & gamification
Streak freezes & power-ups
Streaks are the retention engine, and the fear of breaking one is monetized directly — streak freezes, heart refills, and gems bought at the emotional peak.
- Duolingo Streak Freeze bought with gems (~200 gems)
- Gems also buy heart refills to keep learning after a miss
- Bought on impulse — right when a streak is at risk
- Family plans (Super Family ~$119.99/yr, up to 6) widen the base
Duolingo · and the wider gamified-learning set
Market context only. Prices are representative US list prices for 2025–26 and vary by region, promotion, and plan length; annual plans run ~50% below monthly and several apps have dropped the one-month option. 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 “Education” category.
Paywall shapes
Every learning paywall, rendered from our own components.
The freemium Super unlock, a family plan, and consumable streak freezes — the same primitives, themed for education. These are CashSDK’s unbranded chrome, never a copy of any app’s screen or mascot.
