lessons, locked content, and the free daily limit

Free learners can access the starter lessons and begin one lesson per calendar day. Lumo Plus unlocks all courses and removes the daily lesson limit. If you completed today’s free lesson, return after the next local calendar day begins or upgrade through the paywall.

If an accessible lesson will not open:

  1. Close the lesson sheet and try again.
  2. Confirm the previous required lesson is complete.
  3. Check that your iPhone date and time are set automatically.
  4. Force-close and reopen Lumo.
  5. If you paid for Plus, use Restore Purchases in Settings.

Lumo does not reply

  • Check your internet connection and try a short message first.
  • Wait a moment and retry if OpenAI is temporarily unavailable.
  • Free learners have a limited number of tutor questions per day; Plus removes that app limit.
  • Start a new question without confidential or highly sensitive information.
  • If a reply streams halfway and stops, reopen the Tutor tab and retry.

Lumo is an AI tutor and can make mistakes. Verify important claims against reliable primary sources.

GPT read-aloud is silent or fails

  1. Wait briefly after tapping the speaker: the voice is generated online before playback starts.
  2. Check your internet connection and raise media volume.
  3. Disconnect or check Bluetooth headphones if audio may be routed elsewhere.
  4. Open Lumo Settings and confirm “read-aloud buttons” is enabled.
  5. Tap the speaker once to stop, then tap again to retry.

The voice is generated by OpenAI and is not a human recording. Lumo does not intentionally switch to Apple’s system voice when GPT generation fails.

AI Daily is empty, old, or cannot open an article

Pull down on AI Daily to refresh. The feed depends on public publisher feeds, OpenAI summarisation, and internet access; an individual source may temporarily fail or remove an article. Lumo can show built-in evergreen cards when current stories are unavailable.

If a link fails, the publisher may have moved or removed it. Headlines and Lumo’s context are not a substitute for reading the original article.

hearts, XP, streaks, and progress

Wrong graded answers can cost a heart. Free learners have a limited heart balance; available in-app recovery options appear when hearts run out. Plus provides the paid heart benefits described on the current paywall.

Progress is stored locally rather than in an online account. If the app was deleted, its data was erased, or the device was restored without the relevant app data, support usually cannot recover lessons, XP, gems, or streaks.

daily reminders do not arrive

  1. Enable reminders and choose a time in Lumo Settings.
  2. Open iOS Settings > Notifications > Lumo and allow notifications.
  3. Check Focus modes, Scheduled Summary, and notification delivery settings.
  4. Open Lumo again after changing reminder time so the alert can be refreshed.

iOS controls final notification delivery and may delay or suppress alerts because of device settings.

manage or cancel Lumo Plus

On iPhone, open Settings > your name > Subscriptions > Lumo. You can also use Apple’s subscription-management page.

  • Deleting Lumo does not cancel a subscription.
  • Only a trial or introductory offer shown on Apple’s purchase sheet for your Apple Account applies.
  • To avoid renewal after an eligible trial, cancel at least 24 hours before it ends. Regional rules may differ.
  • For a refund request, use Apple’s Report a Problem. Apple decides refund eligibility.

paid access is missing

  1. Confirm the subscription is active under the Apple Account used to purchase it.
  2. Open Lumo Settings and tap Restore Purchases.
  3. Keep the app open with an internet connection while entitlement status refreshes.
  4. Restart Lumo if the plan still shows “free.”

If restore still fails, email support with the exact error and a screenshot of the active Apple subscription with personal and payment details hidden.

local data, deletion, and reinstalling

Lumo does not currently use an account or cloud backup. Most onboarding answers, progress, tutor history, preferences, and cached stories live only on your device.

Choose “delete all data” in Lumo Settings to remove local learning data and return to onboarding. This action is immediate and cannot be undone. Deleting local data or uninstalling the app does not cancel Plus and does not erase Apple’s transaction records.
