StudyLock vs Orbit Lab

Struggling to stay focused while studying? StudyLock helps you stay on track by blocking distracting apps - and only unlocking them once you’ve studied and passed a quiz. Your study effort can also contribute to real-world educational impact. Whether you're preparing for exams, tackling daily assignments, or working on long-term projects, StudyLock creates a structured, distraction-free study environment powered by AI. How it works: Upload study materials (PDFs, images, or dictate notes by voice) → Block distracting apps (yes, even TikTok) → Chat with your material, create flashcards, generate visual explanations, and review notes with AI → Take a quiz to prove you've studied → Unlock your apps once you meet the score threshold Certain features including AI chat, voice input, Focus Mode, generated visuals, and unlimited uploads require a StudyLockPRO subscription. Features: • Chat directly with your study materials using AI: ask questions, simplify topics, get examples, create flashcards, or request quizzes • Generate visual explanations to better understand difficult concepts • Record voice notes and turn spoken study material into text • Listen as your study material is read aloud • Save completed study conversations and review them later • Download completed sessions as beautiful PDFs with notes, images, code blocks, tables, and key material • Stay focused with Focus Mode, which helps detect lost attention and closes the study screen when you look away • Study together in the Study Room with live study presence, daily check-ins, and community activity • Set your own quiz score requirement to unlock apps • Learn in the language you're most comfortable with • Adjust text size and background for easier reading • Track completed sessions and study time • Get personalised insights and study statistics • Join study groups using your school or organization email • Earn Study Points and contribute them to unlock real donations supporting education Earn your screen time with real study time - and contribute to meaningful educational impact. -------------------------- StudyLock offers premium access through two auto-renewable subscription plans or a one-time lifetime purchase to help you stay focused and boost your productivity: Monthly – StudyLockPRO Access all premium features and unlock your best study flow.

Orbital Lab teaches orbital mechanics by making you fly it: set a launch speed and angle, and a real two-body Kepler solver draws the exact orbit that results — not a canned animation standing in for physics. Every one of the app's 31 lessons ends on a live 3D workbench. Drag the speed slider and watch the path bulge, open into a wide ellipse, or dive into the star; nudge the launch angle and the shape changes again. The same solver computes eccentricity, periapsis, apoapsis, and orbital period from scratch on every frame — nothing is pre-rendered behind the numbers. A lesson only marks complete when you've actually done what it asked — raised the launch speed past the true escape boundary and recovered an orbit just under it, or hunted down the exact speed that avoids a crash — not for pressing Play. Curriculum, unit by unit: • Unit 1 – Orbits from scratch: what an ellipse, periapsis, and escape velocity actually mean • Unit 2 – Solar System missions: fly from Mercury and Venus out past Mars to Jupiter and beyond • Unit 3 – Space engineering: Hohmann transfers, delta-v budgets, gravity-assist flybys • Unit 4 – Deep Space (Pro): the workbench switches engines to a hand-written Verlet n-body integrator, where Kepler's one-body assumption starts to break down Deep Space runs six curated three-body scenes — a figure-eight choreography, a Sun–planet–Trojan system locked at a genuinely stable Lagrange point, and a three-body pass that turns authentically chaotic. Each scene is checked to hold its total energy over the run, so what plays out is real gravity working, not an animation dressed up to look unstable. Explore is a second sandbox: no lesson, no lock, no limit. Set any launch speed and angle and watch the trajectory resolve in real time on the same solver, wide open. Tight circular orbits, wild eccentric ellipses that graze the surface, hyperbolic escapes — try as many launches as you want. Two hand-written physics engines sit behind every screen: a closed-form Kepler solver for two-body mechanics — the exact analytic solution for that problem — and a symplectic Verlet integrator for the n-body cases where Kepler's math stops applying. Neither is a physics library wrapped in a UI. The first Deep Space lesson runs both engines on the same star-and-planet setup side by side, so you can watch them agree. What's free: • Unit 1 in full, plus Mercury through Mars in Unit 2 — 11 of 31 lessons with their live workbenches • The Explore sandbox, unlimited and always available • Progress tracking across all four units • Full light and dark themes, 10 languages What Pro adds: • The rest of the curriculum — outer-planet missions, space engineering, and all of Deep Space — 20 more lessons and their workbenches • Deep Mode: six real three-body simulations • An AI tutor that explains the orbit currently on your screen • No ads Built for the space-curious adult, the physics or astronomy student who wants "orbital velocity" to mean more than a line in a textbook, and anyone who's flown a space sim and wants the actual laws behind it. No science background required — the lessons build the vocabulary as you go. Orbital Lab starts as a guest — no account to create, no sign-in wall. Explore, the first eleven lessons, and your progress are all there the moment you open the app. Sign in later only if you want to. Monthly and annual subscriptions unlock the rest of the curriculum and all of Deep Space, and both plans start with a 3-day free trial. Payment is charged to your account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period; manage or cancel anytime in your device's Account Settings.
