Short answer
Yes. Several iPhone apps turn the time in a screenshot into a calendar event, and this page compares five from official pages, including our SnapCal. Use SnapCal to pull events from Chinese chat and poster screenshots and write them to Apple Calendar and Feishu after you confirm; if your iPhone supports Apple Intelligence and you point the camera at a poster, try the built-in Visual Intelligence first; third-party facts checked 2026-10-14.
How to choose
- The time is hidden in a Chinese chat, group notice or poster and you want to write it to Apple Calendar and Feishu after confirming: SnapCal.
- Your iPhone supports Apple Intelligence and you can use the camera on a poster: the built-in Visual Intelligence, no app needed.
- You want a Chinese interface, several events from one image and repeat rules: Screenshots to Calendar.
- An English-only interface is fine and you need Google or Outlook calendars: EventShot.
- You want a one-press Action button trigger inside WeChat and a notification at event time: Todoo.
Five options in one table
| App | How it works | Requirements and price | Where data goes | Source (checked 2026-10-14) |
|---|---|---|---|---|
| SnapCal | Triggered from the Share Sheet, Shortcuts or Recent Screenshots in the app; a confirm screen lets you edit title, date, time and place; writes to the iPhone calendar and optionally Feishu; one event per screenshot | iPhone; free tier 10 reads a month, subscription ($1.99 monthly or $9.9 yearly) or lifetime membership unlocks unlimited use, the price in the app applies | The compressed screenshot is sent to an AI processing service to read the event and is not kept afterwards; on-device OCR is only for the preview and is never uploaded | App Store page |
| Apple Visual Intelligence | Point the iPhone camera at the subject, then tap Add to Calendar and Create Event. The official page describes a camera scenario; whether it works on screenshots: not verified | Needs Apple Intelligence: iPhone 15 Pro, 15 Pro Max or iPhone 16 and later, iOS 27; not available in every language and region; built in, no separate charge | System feature | Apple Support: Use Visual Intelligence on iPhone |
| Screenshots to Calendar (Blocksize One UG) | Import by screenshot, photo, Share Sheet or clipboard; extracts title, date, time, place and video-call links; the listing states recurring patterns and multiple events from one image; interface languages include Chinese | iOS 17.0 or later; free to download in the US store (in-app purchases: not verified) | Not verified | App Store page (US) |
| EventShot (Lauper Labs) | Screenshot or pasted text; extracts title, date, time and place and saves to Apple, Google or Outlook calendars | iOS 18.0 or later; free to download in the US store, listing says "Rate limits apply"; English interface only | Listing says all scanning happens on the device | App Store page (US) |
| Todoo (汝衡 冯) | Triggered with the Action button in WeChat; recognizes events from text, images and voice, listing says it can extract several at once and notifies you at event time | iOS 17.0 or later; free to download in the China store (in-app purchases: not verified); Chinese interface | Not verified | App Store page (China) |
Third-party entries come from official App Store pages (read through Apple's iTunes Lookup API) and Apple Support, and are the developers' or Apple's own statements, not our tests. Prices and requirements change, so check the App Store page on the day you download. "Not verified" means we did not see it on an official page, not that it does not exist.
What each does well
- Apple Visual Intelligence: nothing to install; point at a poster and tap Create Event, with privacy and stability handled by the system. The bar is the device: an iPhone that supports Apple Intelligence.
- Screenshots to Calendar: the listing says it can pull several events from one image and read repeat rules, which SnapCal does not do today (one event per screenshot).
- EventShot: saves straight to Google and Outlook calendars, and its listing says scanning stays on the device.
- Todoo: built around WeChat with an Action button trigger and notifications at event time, another route for Chinese users.
- SnapCal: clear rules for Chinese chat screenshots (chat screenshots always go through a confirm screen before writing), every field editable before writing, Feishu sync, and confident non-chat screenshots are written directly with a 10-second undo.
Costs and limits
- SnapCal is iPhone only; there is no Android version. One screenshot produces one event, a full timetable is not split into courses, and reading needs a network because the compressed screenshot goes to an AI processing service.
- The free tier has 10 reads a month and only a real write to the calendar counts; after that you need a subscription or the lifetime membership.
- Every reader gets some wrong, which is why each app above keeps a confirm step; try a few of your usual screenshots first.
