# Review credits, missions, and XP

Free-plan study uses review credits. Pro-plan reviews are unmetered. Check the active plan in **Settings → Account Info**.

Review credits pay for study sessions; XP tracks level progress; AI uses a separate weekly allowance. These values are not interchangeable.

## Earn and claim mission rewards

1. Open **Home** and tap **Missions** in the progress card.
2. Choose **Daily** or **Weekly**.
3. Read the requirement and displayed reward for each mission, such as **Daily check-in** or reviewing a number of cards.
4. When the mission is ready, tap **Complete** to claim it.
5. Confirm that the state changes to **Claimed** and check the updated progress.

The progress card shows your level, XP toward the next level, and consecutive check-ins. A check-in streak follows the mission check-in rules; it is not a count of all days on which you opened a card.

Use the reward values displayed in the app. Mission requirements, credit rewards, ad quotas, and cooldowns are supplied by the service and can change. Pro accounts do not receive mission review credits and do not show rewarded-ad controls.

## Watch an ad for review credits

For eligible Free accounts, **Watch Ad** appears in the Daily missions view and in **Not Enough Review Credits** dialogs. It is a repeatable earning opportunity, rather than a mission that you claim once.

1. Connect to the internet and open **Missions → Daily**, or the insufficient-credit dialog.
2. Read the current reward, quota, or cooldown.
3. Tap **Watch Ad** when available.
4. Watch the full ad and close it when permitted.
5. Wait for the reward to be verified and the balance to update.

Closing early or an ad failing to load does not earn credits. A completed video is followed by verification; the balance may not change immediately.

If the message says **Your reward is still being verified**, wait and return to the app later. If it says the reward was confirmed but the balance needs updating, open **Settings → Account Info → Sync Status → Sync Now**. Repeatedly tapping another ad is not a substitute for verification.

## Reset times

| Period                           | Reset               |
| -------------------------------- | ------------------- |
| Daily missions and check-in days | 00:00 UTC           |
| Daily rewarded-ad quota          | 00:00 UTC           |
| Weekly missions                  | Monday at 00:00 UTC |

For example, midnight UTC is 08:00 in Taiwan. The app's **Resets in** countdown helps you follow the active period.

The **Next Day Starts At** study setting controls SRS daily limits and study-day statistics. Changing it does not shift missions or the ad quota.

## Resolve credit problems

- **Not enough credits:** claim eligible mission rewards or use an available rewarded ad before continuing.
- **Cooldown or daily limit:** wait for the time shown or the next UTC quota reset.
- **Ad unavailable:** check the connection and retry later; availability is not guaranteed.
- **Balance seems outdated:** use **Sync Now**, then reopen the relevant view.
- **AI usage limit reached:** check [AI Settings](https://docs.flashnerd.com/guide/ai/limits-and-sources.md); earning review credits does not restore AI allowance.
