How can we help?

By default, no. Nosce's headline feature is a Notice — a gentle notification that taps you on the shoulder when you've been in an app too long. The phone stays unlocked and you can keep going.

If you want a real wall, you can opt in to a Pact, which uses iOS's shield to lock an app after a daily or per-sitting cap. Pacts are hidden by default and entirely your choice.

A Notice interrupts — it sends you a message you wrote and lets you decide. A Pact enforces — it shields the app when you cross a limit. Notices are the default; Pacts are an optional, stronger guardrail for the apps where noticing isn't enough.

Apple's Screen Time framework hands apps opaque tokens, not names or exact usage numbers. iOS measures your usage on-device and only tells Nosce when a threshold is crossed. This is a privacy protection built into iOS. For optional Shared Pacts, Nosce syncs your display profile plus the kept/missed result, chosen app label, daily cap, Pact minutes, and estimated all-apps screen time for the pact you chose to share.

A few things to verify:

1. Screen Time permission — iOS Settings → Screen Time → make sure Nosce is allowed. Nosce also shows this status on its own Settings screen.

2. Notifications — iOS Settings → Notifications → Nosce → Allow Notifications.

3. The active window — a Notice only fires inside the time window and on the days you set.

4. Pause — if you've paused Nosce, notices won't fire until the pause ends. Look for the banner on the Today screen.

Screen Time data updates on iOS's own schedule, so a brand-new notice can take a little while to trip the first time. Still stuck? Email us.

A Shared Pact lets you and one other person commit to a daily limit on an app together. You create the pact, send an invite link, and your partner joins. Progress syncs through Nosce's server so you can keep each other accountable. Both people see each other's display profile, daily result, chosen app label, daily cap, Pact minutes, and estimated all-apps screen time.

Both people need Nosce installed on an iPhone.

Subscriptions are handled by Apple. Open iOS Settings → [your name] → Subscriptions, select Nosce, and change or cancel there. Nosce never sees your payment details.

Nosce is iPhone-only and requires iOS 17 or later. It is not a parental-control app — it's for the person installing it on their own device.

Nosce stores most data on your device, so deleting the app from your iPhone removes it. To remove Shared Pact server data, delete the pact inside the app, or email us and we'll help. See the privacy policy for details.
