What Super Duolingo Includes

Duolingo operates a freemium platform supported by display advertisements and a energy/heart system that penalizes mistakes. Super Duolingo removes these restrictions:

  1. Unlimited Hearts: The free version of Duolingo docks one heart for each mistake; losing all five hearts pauses study until they regenerate over several hours or are refilled with in-app gems. Super Duolingo removes heart limits, allowing uninterrupted study.
  2. Zero Third-Party Advertising: Video and display ads between lessons are removed.
  3. Personalized Practice Hub: A dedicated review section groups previous errors, weak vocabulary words, and listening comprehension drills into targeted recovery sessions.
  4. Unlimited Legendary Level Attempts: Free accounts spend gems to test for Legendary mastery badges at the end of learning units. Super accounts take Legendary tests without gem deductions.
  5. Timed Challenge Entry: Access to Lightning Rounds and Match Madness mini-games without spending in-game currency.

Step-by-Step Guide: How to Claim the 12-Month Subscription

Follow these verified steps to activate the offer on Android or iOS devices:

Step 1: Install and Update the Airtel Thanks App

Ensure you are running the latest version of the Airtel Thanks app from the Google Play Store or Apple App Store.

Step 2: Log in with Your Active Airtel Number

Open the app and authenticate using your primary Airtel mobile number via one-time SMS password (OTP). The account must have an active recharge plan (prepaid) or an active billing cycle (postpaid).

Step 3: Open the "Rewards" or "Discover Thanks" Section

On the bottom navigation bar or top account banner, tap Thanks Benefits or Rewards.

Step 4: Locate the Super Duolingo Banner

Scroll through the digital partner offers to locate Super Duolingo: 12 Months Free Access.

Step 5: Tap "Claim Now"

Tap the claim button. The app will generate a unique 12-month alphanumeric promotional code or provide an authenticated direct activation link.

Step 6: Redeem in Duolingo

  • If redirected through a deep link: Duolingo will launch automatically and prompt you to confirm the 12-month upgrade on your account.
  • If given a coupon code: Open a mobile browser, visit duolingo.com/redeem, sign in to your Duolingo account, paste the code, and confirm.

Eligibility Rules and Edge Cases

  • Prepaid Customers: Available on active bundled unlimited voice and data recharges. Data-only add-on packs without base validity do not qualify.
  • Postpaid Customers: Available on all active individual and family postpaid connections. Each individual Airtel SIM in a family plan can claim its own code through the Airtel Thanks login linked to that number.
  • New Duolingo Users: You can create a new Duolingo profile during redemption; all progress tracks under the Super status immediately.
  • Existing Free Duolingo Users: Your current streaks, XP, unit progression, and friend lists remain completely intact when upgrading to Super.
  • Existing Paid Super Duolingo Subscribers: If you have an active Apple App Store or Google Play subscription, you cannot stack the promo code on top of an active recurring payment. Turn off auto-renewal in your app store settings. Once your current paid period finishes, apply the Airtel promotional code to start the free 12-month period.

Telecommunications Strategy: The Race for Indian Digital ARPU

India is Duolingo’s fastest-growing national market by daily active users. While raw downloads have surged over the past three years, free-to-paid conversion rates in price-sensitive emerging economies traditionally hover below 2%.

By partnering with Bharti Airtel, Duolingo bypasses individual credit card friction and payment gateway hesitations, seeding 376 million users with its premium experience for a full calendar year.

For Airtel, the partnership addresses key competitive dynamics:

  1. Churn Reduction: Telco subscriber churn drops significantly when users anchor high-utility services—such as educational tools and language learning—to their monthly mobile recharges.
  2. Thanks App Daily Active Users: Channeling claims exclusively through the Airtel Thanks app increases daily app opens, exposing subscribers to bill payments, broadband upgrades, Airtel Payments Bank, and financial services.
  3. Competitive Differentiation: Rival operators Reliance Jio and Vodafone Idea (Vi) bundle video streaming services like Disney+ Hotstar and SonyLIV. Airtel’s partnership targets self-improvement, professional upskilling, and academic preparation (such as the Duolingo English Test used for global university admissions).

Popular Language Courses for Indian Learners

Data from Duolingo’s annual language reports indicates specific linguistic interests across the Indian subcontinent that this offer directly impacts:

  • English: Remains the most-studied language across Tier-1, Tier-2, and Tier-3 Indian cities, functioning as a primary vehicle for white-collar employment, software engineering interviews, and business operations.
  • Hindi from English: Widely used by domestic migrants and professionals relocating across different states.
  • Korean & Japanese: Driven by global pop culture, anime, and industrial manufacturing ties, Korean and Japanese have become the fastest-growing foreign language subjects among Indian university students.
  • French & German: Heavily studied by software engineers and university applicants seeking European work visas and tuition-free higher education in Germany.

The free 12-month Super Duolingo tier allows learners to study multiple languages concurrently without penalty or lesson caps.


Troubleshooting Common Redemption Issues

If you encounter issues claiming or activating the 12-month voucher, follow these verified fixes:

  1. Offer Banner Missing in Airtel Thanks App: Ensure the app is updated to the latest build from the Play Store or App Store. Log out and log back in with your registered Airtel number. The offer rolls out sequentially across telecom circles; users in priority circles (Delhi-NCR, Mumbai, Karnataka, Tamil Nadu, Andhra Pradesh) receive instant visibility, with nationwide availability completing over 72 hours.
  2. "Code Already Redeemed" Error: Check if another family member on your shared plan claimed the voucher code. If claiming on a shared family plan, each primary SIM requires individual login to generate a distinct voucher.
  3. Active App Store or Google Play Billing Conflicts: Duolingo does not allow promotional vouchers to overwrite active Google Play or Apple App Store recurring subscriptions. Cancel auto-renewal in Google Play Store $\rightarrow$ Subscriptions, wait until your current paid month completes, and enter the voucher at duolingo.com/redeem.
  4. Voucher Expiry: Generated claim codes must be redeemed on duolingo.com/redeem within 30 days of generation from the Thanks app.
