How to Upgrade to a Subscription

Ronaldo, a pragmatic construction manager, upgraded after 34 days of free use when he tapped "Advanced Analytics" and saw the upgrade prompt. He wanted a fact-type breakdown to show his neurologist — proof that his brain was healing in a measurable way. This guide walks through upgrading your account.

Subscription Options​

OptionWhat It Includes
Ad-free (Tier B)One-time purchase to remove all ads permanently. Requires creating an account.
Basic Subscription (Tier C)Monthly or annual. Removes ads + unlocks cross-device sync, Advanced Analytics, adaptive difficulty, and push notification reminders.
Premium Subscription (Tier D)Monthly or annual. All Tier C features plus future premium capabilities.

How to Subscribe​

  1. Tap any locked feature — for example, tap Advanced Analytics on the Progress tab.
  2. An upgrade prompt appears explaining the benefits of subscribing.
  3. If you are anonymous (no account yet), the app prompts you to create an account first. Choose Google Sign-In, Apple Sign-In, or email. All your existing session history is preserved during this upgrade.
  4. After account creation, the subscription purchase screen appears.
  5. Select your plan (monthly or annual) and complete the purchase via the App Store or Google Play.
  6. The subscription activates immediately — the previously locked feature becomes accessible.

From Settings​

  1. Go to Profile > Subscribe (or Profile > Settings > Manage Subscription).
  2. Review the subscription benefits listed.
  3. Tap Subscribe and select your plan.
  4. Complete the purchase.

Removing Ads Only (Ad-free, Tier B)​

  1. Go to Profile > Settings and tap Remove Ads.
  2. If you are anonymous, create an account first (the same account creation flow as above).
  3. Complete the one-time IAP purchase.
  4. Ads disappear immediately from all screens.

Expected Outcome​

After subscribing, your tier updates immediately. Locked features become accessible. If you subscribed to Tier C:

  • Cross-device sync activates — data starts syncing to the server
  • Advanced Analytics unlocks on the Progress tab
  • Adaptive difficulty activates (monitors your 7-session rolling average)
  • Push notifications become configurable in Settings

Restoring a Previous Purchase​

If you reinstall the app or switch devices, go to Profile > Settings > Restore Purchases. The app checks your App Store or Google Play account for prior purchases and restores your tier.
