123 ToDo review
A portable free task manager with strong privacy features and limited calendar workflow coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
123 ToDo is a browser-based task management app for individuals, professionals, freelancers, families, and field workers. It combines priority-based organization with a four-level priority matrix, projects, due dates, recurring tasks, subtasks, notes, photo attachments, and voice dictation. The app runs across web, Windows, macOS, Linux, iOS, and Android, with cloud, mobile, and desktop deployment. Its free positioning makes it particularly suitable for solo users and small teams that want task management without a subscription commitment.
Portability is a major part of the product’s appeal. Users can import from Todoist, TickTick, Google Keep, Google Tasks, and Microsoft To Do, then export task data as JSON. Local shadow backups add another data-handling option, while offline Progressive Web App access supports desktop and mobile use without relying on a continuous connection. Optional synchronization through 123 ToDo Cloud Sync or Google Drive is encrypted across devices, and the product emphasizes local-first storage with client-side AES-256-GCM encryption. Google Drive, WebDAV, and Cloudflare D1 are listed integrations.
The free plan includes priority-based task management, recurring tasks, subtask checklists, offline PWA access, and encrypted cross-device sync. Scheduling also includes due dates and task deferral, while attachments and voice dictation broaden task capture. Support is provided by email, and GDPR is listed among the compliance areas. 123 ToDo should suit users who value privacy, offline access, and control over moving their task data between services. Users whose core workflow depends on verified calendar synchronization, task-specific reminders, or a wider support model should consider a more calendar-centered alternative.
