Digit Span Trainer

About Digit Span Trainer

Train your working memory with Forward, Backward, and Sequencing challenges. Choose visual or spoken digits, repeat them correctly, and build your span over time.

Free Core:

• All three Classic modes and Training Journey
• Visual and audio presentation
• Personal bests, charts, accuracy, streaks, and recall speed
• Local Next session recommendations
• CSV import and export
• Multiple visual themes
• Ad-free and usable offline without an account

Digit Span Lab — optional permanent unlock:

• Save custom local training programs and presets
• Run advanced local mode-switch, dual-channel, and overload drills
• Study serial-position errors and response-time patterns
• Compare recent and prior performance in deeper local reports
• Set local goals and share a saved report snapshot
• Pay once through Google Play; no Coach sign-in required
• Lab includes no AI Coach credits

Span Coach — separate optional service:

• Sign in to claim 10 lifetime personalized Coach samples, with one available per UTC day
• Turn a Coach plan into a focused five-round session and review the result
• Add a repeatable one-time Coach Pack with 365 non-expiring insights
• No Coach subscription is offered to new customers; an existing legacy subscriber can still manage the subscription already purchased

A Lab refund or revocation relocks Lab editing and drills without deleting saved local programs or the last saved report. Generated Span Coach plans and reviews require Google sign-in and an internet connection. Signed-in users can permanently delete their Coach cloud account in More > Settings > Account. The Google-authenticated account-deletion page linked from Google Play works without the app.
