## FlowBuddy: App Blocker & Focus App

FlowBuddy tackles phone overuse with friction rather than total lockdown. Instead of blocking everything outright, it inserts a brief, mindful pause before a distracting app or website opens, so you have a chance to reconsider whether you actually want to be there. Blocking is built on Apple's Screen Time shielding APIs, which means it works reliably on iPhone without jailbreaks or profiles you have to babysit.

Setup is deliberately simple: choose the apps, categories (like Social or Games) or web domains you want to shield, then decide how access works. You can define allowed schedules so work hours stay protected, choose from unlock mechanisms, and track how often you try to open blocked apps so you can see habits shifting over time. The app also adds a Tamagotchi-style character that sleeps at night and reacts when you unlock too often, a small nudge that makes the pause feel friendly rather than punitive.

FlowBuddy is built by a small independent developer (Costin Bernhart) and is free to download with an optional Pro upgrade and in-app purchases. Note that an earlier AI-flashcard quiz feature was retired in version 1.4.0 — the current focus is purely on blocking, mindful pauses and habit tracking.

**Pricing & Plans:** Free to download with in-app purchases; a Pro tier (including lifetime access) unlocks additional unlock mechanisms and customization. Verify current prices on the App Store.

- **App, category and website blocking:** Shield individual apps, whole categories such as Social or Games, and web domains using Apple's Screen Time framework.
- **Mindful unlock mechanisms:** Restore access by completing a breathing exercise or other intentional action, so opening an app never happens on autopilot.
- **Allowed schedules:** Define time windows when apps block and unblock automatically, with times that hold steady across time zones and daylight saving changes.
- **Usage tracking:** See how often you attempt to open blocked apps and watch your habits improve over weeks.
- **Reactive companion character:** Your FlowBuddy sleeps at night and reacts when you unlock apps too often — a light Tamagotchi-style motivator.

**Strengths:** Reliable blocking built on native Screen Time APIs; Flexible unlock mechanisms far less rigid than hard lockdowns; Simple setup with no complex configuration required; Frequently updated by an active solo developer

**Limitations:** iPhone only — no Android or desktop version; Advanced unlock options sit behind the Pro purchase; The retired flashcard feature means it is now blocking-only

## Knowt

Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative. Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting.

The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go.

Knowt is free to use for core studying, with unlimited learn mode and free practice tests. It is widely adopted in education, with millions of students and teachers using it and a strong presence in AP exam preparation, alongside SAT and ACT resources and a Chrome extension for on-screen study.

**Pricing & Plans:** Knowt's core features are free: unlimited learn mode, free practice tests, flashcard creation, imports, and AI study tools with reasonable usage limits. Optional paid upgrades (Plus/Unlimited-style tiers) unlock higher AI generation limits and premium features. No credit card is required to start studying.

- **AI PDF Summarizer and Flashcards:** Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
- **Import and Lecture Recording:** Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
- **Exam Predictor and Planner:** Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
- **Voice Tutoring and Podcasts:** Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.
- **Study Modes and Exam Prep:** Free learn mode, matching games, spaced repetition, and practice test rooms cover AP, ACT, and SAT prep.

**Strengths:** Free core with unlimited learn mode and practice tests; One-click Quizlet import preserves formatting and images; AI turns PDFs, slides, and lectures into study materials; Strong AP, SAT, and ACT prep resources plus a Chrome extension

**Limitations:** Some AI generation limits encourage upgrading to paid plans; Advanced study plans rely on accurate file uploads; Best experience requires creating an account to save materials
