Night-only screen time blocker for the phone-to-bed transition
Problem
Existing screen time apps are built around all-day limits and subscriptions. People who only struggle with the nighttime transition (putting the phone down before bed) can't find an app with time-based blocking, a single shared 'one more minute' across all apps, and a one-time payment instead of a subscription — even after trying suggested apps, the gap remains.
Opportunity
A focused, buy-once app that enforces a wind-down window at set hours: apps freeze after bedtime, one single 'one more minute' grant across all apps per night, no daily limits during the day. The OP of the thread explicitly documented that ScreenZen, Foqos and Halo each fail at least one of these criteria.
Market analysis
The gap the OP documents is real: most blockers are all-day limit meters gated behind subscriptions, and the closest incumbents are free (ScreenZen, open-source Foqos). A buy-once, night-only app is a viable solo project, but it has to win users against $0 alternatives on one clever mechanic.
Market · People with healthy daytime usage and one specific bedtime failure mode; persistent 'can't put my phone down at night' threads prove recurring demand.
Pricing · Anchors are free (ScreenZen, Foqos), Jomo at $29.99/year, and the $44 one-time Halo device; a $5-15 one-time purchase is the realistic ceiling for this niche.
Pros
- + Laser-sharp scope: a time-window block plus one shared 'one more minute' is a small, shippable MVP.
- + Buy-once positioning directly answers documented subscription fatigue in the category.
- + Proven category spend (Jomo, Brick, Halo) with no exact feature match today.
Cons
- − Free incumbents (ScreenZen, Foqos) already cover most of the ask.
- − One-time pricing caps revenue per user and rules out paid acquisition.
- − iOS Screen Time API quirks make reliable scheduled blocking fiddly.
- − App stores are saturated with screen-time apps; discovery is the bottleneck.

The genuinely novel constraint is the single shared ‘one more minute’ across all apps: per-app grants are exactly why existing blockers fail at night, since users burn one minute in each app and lose the evening anyway. On iOS there is no native global grant, so orchestrating one shared budget across Screen Time shields is the real engineering work, and nobody appears to have bothered. That detail, not the schedule itself, is the product. The biggest external risk is Apple shipping an equivalent as a native Sleep feature, which would erase the category overnight.
