Stop opening social media on autopilot. one sec adds a short pause before distracting apps so you can choose what deserves your attention. This principle works really well: we have gained scientific evidence in numerous research studies with the Max-Planck Institute, with the German and Danish government, and in dozens more scientific collaborations: one sec has incredible effects on your screen time: app usage drops by 57% on average! …just read our App Store reviews or try it for yourself if you don’t believe me (…you should really try it)! How is one sec different from Screen Time limits or app blockers? - one sec DELAYS access to distracting apps instead of blocking apps completely – that’s an important difference psychologically. - This way, we solve the screen time problem at its roots: long-term & sustainably! - one sec is always on, and makes using social media just slightly more annoying…so you’ll end up using it only when you actually have a reason! Which apps can I use with one sec? - You can set up one sec with any app you’d like to use less / more intentional. - Most popular use-cases are: social media, games, video streaming, dating, stock/coin trading, adult content. - Using one sec with one app of your choice is completely free, for more you’ll need to purchase one sec pro (we also need to finance development of our app!). What if I get stuck scrolling? - No worries, one sec offers a Doom Scroll Emergency Brake: We call it Re-Intervention. - After a set time (e.g. 5 minutes) you’ll be kicked out of social media, and you’ll have to go through an intervention again to unlock more time. Where can I learn more about the scientific background of one sec? → https://one-sec.app/research Can I use one sec to interrupt access to websites as well? → Yes, one sec offers a free Safari extension as well. How does one sec work technically? - one sec uses Shortcuts Automation to toggle a deep breath animation whenever you open one of the configured apps (Instagram, Twitter, YouTube…). - This breaks unconscious social media habits short-term (literally, as soon as you have set it up) and even helps long-term by adding more friction when opening these apps. Integrations: - Structured: one sec blocks apps during unfinished tasks. - LENGO: learn vocabulary to unlock social media. I developed one sec for myself in 2020…and it worked so well I decided to upload it to the App Store. Especially for people with ADHD one sec is a great tool to gain back control for incredible focus and concentration. – Frederik Legal information: Available Subscription Options: one sec pro (annual / monthly / lifetime unlock) one sec can contribute mindful moments to the Health App via HealthKit. one sec is covered by U.S. Patent 12,468,828 B2.

About

Warikomi TODO

Read full description

WARIKOMI TODO is a reminder app that displays your TODO memo just before you open an app you have selected. Instead of sending a notification at a set time, it turns your everyday app habits into a cue to remember what you need to do. KEY FEATURES • Show TODO memos before opening selected apps • Complete a TODO or temporarily skip it to continue to the selected app • Schedule memos for every day, selected weekdays, specific dates each month, and time windows • Show memos repeatedly • Move unused TODOs to Stock and restore them when needed • View your TODOs alongside the icons of their selected apps • Restore your purchased Premium plan HOW IT WORKS 1. Write a TODO you want to remember. 2. Choose the app that will trigger your memo. 3. Set the days and time window. When your schedule conditions are met, your TODO appears just before the selected app opens. For example, attach a memo to a social app you check regularly and set it to appear only between 6 AM and 9 AM. Opening that app can remind you to: • Check a social media post you don't want to miss • Check what you need to take before leaving home Outside the 6–9 AM window, that memo will not appear when you open the same app until the next scheduled day. You can also: • Attach a memo to a game so you remember an in-game event you want to complete. • Attach a memo to a video app with a routine you want to fit into your day, such as “Do squats while watching.” There are plenty of ways to make it work for you. For recurring TODOs, you can set a memo to become eligible to appear again after a chosen interval. It's useful for things you want to remember throughout the day without having to do them at an exact time. It's a flexible approach to TODOs, built around opening apps rather than notifications at preset times. Choose time windows, weekdays, or specific dates each month to control when your memos can appear. Which apps will you stick your memos to? FREE PLAN Create up to 1 active TODO memo. PREMIUM PLAN Create up to 10 active TODO memos. You can also attach multiple TODO memos to the same app. Premium is available as a monthly or annual subscription. Payment is charged to your Apple Account, and your subscription renews automatically unless canceled. Prices and subscription periods are shown on the purchase confirmation screen. You can manage or cancel your subscription at any time in your iPhone's Settings. BEFORE YOU START Permission to use Apple's Screen Time features is required to display TODO memos before your selected apps open.
