iPhone lock screen cluttered instead of showing only a to-do list: SKIP, 35/100 | Ideas Lab

A lock screen replacement that shows a to-do list instead of the default iPhone interface.

The pain

Users switch between their lock screen and task management apps multiple times daily, creating friction in their workflow. The lock screen shows time and notifications but not actionable tasks, forcing an extra unlock to see what needs doing.

The gap

Apple's lock screen customization (iOS 16+) allows widgets but not full replacement. Existing to-do apps (Todoist, Things, Reminders) don't integrate into the lock screen experience. Users must choose between seeing their tasks or their notifications/time.

Build angle

This requires jailbreaking iOS or using Apple's limited widget API, both of which severely constrain what's possible. Apple actively prevents third-party lock screen replacement. Even if technically feasible, Apple could block it at any update. The actual problem, task visibility, is better solved by improving notification integration or home screen widgets, which don't require fighting iOS architecture.

Strengths

Clear user pain point: task visibility on lock screen
Narrow, focused feature set reduces scope
Existing to-do app market proves demand exists

Risks

Apple's iOS architecture fundamentally blocks third-party lock screen replacement without jailbreak
Any solution violates Apple's App Store policies and gets rejected or removed
Users who jailbreak represent <5% of iPhone base and face security/stability issues
Apple's own lock screen widgets (iOS 16+) directly compete and improve over time
No sustainable business model if app gets banned from App Store
High churn: users abandon jailbroken devices or update iOS and lose the app
Solving the real problem (task visibility) doesn't require replacing the lock screen

Is the pain real, is there a gap, is it the right time, can one person build it.

No easy way to hide Instagram stories from specific groups like coworkers

Instagram lacks a reverse 'close friends' feature to quickly hide stories from select people (e.g., colleagues) without hiding from everyone.

Manual document processing creates bottlenecks in business workflows

Businesses waste time manually extracting data from invoices, contracts, forms and other documents. This creates delays and errors in workflows that depend on this information.
