Your assignments, together. Stop copying deadlines from different course sites one by one. ReminderSnap reads assignment screenshots, photos and PDFs on your device. Review the results, then keep your deadlines in one assignment calendar. • Start with Your Task Calendar, organized by course colour and a clear legend. • Import screenshots and PDFs, or photograph a laptop screen on iPhone and iPad. • Check and edit titles, courses, sections, real deadlines and timezones before saving. • Edit course preferences, archive finished courses and correct the course for each image. • Enable ReminderSnap notifications and choose when to be alerted before a deadline. • Sync confirmed assignments through your private iCloud account when available. • Choose your workflow: stay in ReminderSnap, connect Apple Reminders and Calendar, or optionally sign in to Google Calendar. • Keep the real deadline while using optional planning blocks to make late-night deadlines easier to see. • Update linked entries from ReminderSnap and remove multiple linked planning blocks while keeping assignments. • Use English or Simplified Chinese on Mac, iPhone and iPad, with a visual first-launch guide and sample preview. Recognition works locally, including offline. No school-account login, advertising, analytics SDK or AI subscription. Screenshots and raw recognized text are not uploaded to the developer or an AI service. Network access is needed for iCloud synchronization and Google Calendar connections. Calendar connections and notifications are optional and depend on your permissions and account settings. Google access is limited to calendars created by ReminderSnap. Linked edits made in ReminderSnap update external entries; edits made in external calendar apps are not automatically imported. Apple-linked updates run on the original exporting device. Always review extracted information before saving. Recognition depends on clarity and layout. Missing details may need confirmation. Notification delivery depends on system settings and Focus. Each device requires its own notification permission. iCloud synchronization may be delayed.

Verdict
The clearest difference is in-app purchases: ReminderSnap at none against STL Simple Viewer's 4. ReminderSnap also leads on ads (none vs shown) and update cadence (weekly vs every 5 months). On price, device support and iOS requirement there is nothing between them.
