Help & Support

Tincall connects your iPhone to AI model and speech services you configure. It requires iOS 26.0 or later.

Make your first call

1. In Settings > API Settings, save a model preset with the provider's address, API key and model name. Test the connection.
2. In your profile at the top of Settings, choose a speech recognition service. Apple on-device recognition does not require an API key. Check the selected recognition language and on-device readiness.
3. In Settings > Text-to-Speech Settings, add and test a speech synthesis preset.
4. In Contacts, tap +, enter a name, choose Independent mode, and select your model and speech preset. Save and tap the phone button.
5. Allow microphone access. Speak or switch to text to send a message. You can interrupt a reply and hang up when finished. Recents contains local call records.

Independent mode does not require a Tincall cloud deployment. MCP, custom backend, cloud sync and incoming calls require the corresponding external services. Model, speech, hosting and network providers may require their own accounts, allowances or fees.

Trial and lifetime unlock

The App Store version offers a free seven-day trial followed by a separate one-time purchase to unlock core calling. The trial does not renew or charge automatically. Use Settings > Trial & Unlock to start the trial, buy the lifetime unlock or restore purchases with your Apple account. Existing records, settings and help remain accessible after expiry. Provider charges are separate from the app purchase.

Text appears but there is no sound

Test the selected voice in Text-to-Speech Settings. Check the provider's balance, network access and the output device. Confirm that the contact selects the intended speech preset.

Speech is choppy or replies take a long time

Check whether audio playback is stuttering or the model is still generating. Test the voice preset, inspect any reported service error and temporarily try the iPhone speaker to isolate a Bluetooth routing issue.

Recognition is inaccurate

Check microphone permission, background noise and the recognition language. If you request support, explain whether whole phrases, individual words or interruption detection are affected.

Speaking does not interrupt a reply

Confirm that speech interruption is enabled and that speech produces valid recognition. Manual interruption and speech interruption are separate controls. Explain whether the app was waiting for a reply or already playing audio.

Incoming calls do not ring

Incoming calls require the correctly signed app, a valid device binding, APNs support and an online sender. Chuli maintains the official App Store version's push relay; you do not need to configure Apple push credentials for that relay. There is no separate push fee. Self-signed or independently deployed versions require matching signing and push services. Device registration does not prove APNs delivery or that a phone rang.

AI output

Replies, transcriptions and summaries may be inaccurate, incomplete or misleading. Generated content does not represent Tincall's or the developer's views. Verify important information and do not rely on Tincall for professional advice or emergency assistance.

Send feedback

Email tincall@chuli.win, or use Submit Feedback in the app's Help page. Include the issue, expected result, repeatable steps, app/iOS versions, device model and relevant connection mode. Screenshots are optional.

If you modified the source, check whether the unmodified official version has the same issue. The developer does not commit to maintaining modified versions or resolving every report. Review attachments and remove secrets and private conversations before sending.
