App support

Help for AfterBite, NoteFolio, FeatureFlow, and LaterLinks on iPhone and iPad. All four apps require iOS or iPadOS 17 or later.

Contact support

Email enquiries@xntric.io and include:

  • The app name and version (shown in the App Store or the app’s settings)
  • Your device model and iOS or iPadOS version
  • What happened, what you expected, and the steps that cause the issue
  • A screenshot or screen recording, if you can

None of our apps use accounts, so we can’t look up your data. The more detail you send, the faster we can help.

Restore a purchase

If you bought an upgrade or subscription and it isn’t showing, open the app’s upgrade screen and tap Restore Purchase. Make sure you’re signed in with the same Apple Account you used to buy it.

Manage or cancel a subscription

Subscriptions (AfterBite Pro and FeatureFlow Pro) are billed and managed by Apple. To change or cancel one, open Settings, tap your name, then Subscriptions. Deleting the app does not cancel a subscription.

Refunds

All payments are processed by Apple, so we can’t issue refunds directly. You can request one at reportaproblem.apple.com.

iCloud sync

Sync is optional and uses your own private iCloud account. If data isn’t appearing on another device:

  • Check that sync is turned on in the app on every device.
  • Check you’re signed in to the same Apple Account on each device, with iCloud turned on for the app (Settings → your name → iCloud).
  • Keep the app open for a minute while connected to the internet. Changes can take a few minutes to arrive.

App notes

AfterBite: Track & Feel Better

AfterBite can read data from Apple Health with your permission. It only reads data and never writes to Health. You can change access at any time in Settings → Health → Data Access & Devices. AfterBite is a diary and pattern-finding tool. It does not provide medical advice, diagnosis, or treatment, so talk to a healthcare professional about your symptoms.

NoteFolio: Digital Notebook

Two notebooks are free with every feature. A one-time unlock adds unlimited notebooks and folders. There is no subscription.

FeatureFlow: Backlog Manager

FeatureFlow Pro adds unlimited workspaces and unlimited features per workspace, and is available as a monthly, annual, or lifetime purchase.

LaterLinks: Ready when you are

The free version holds up to 15 links and 3 tags. A one-time Pro unlock adds unlimited links and tags, iCloud sync, archive, per-link reminders, and the tag-grouped view. To save from another app, tap Share and choose LaterLinks. If it isn’t listed, scroll to the end of the app row, tap More, and add it.

Privacy

Our apps have no accounts, no ads, and no third-party analytics. Read the full privacy policy.
