Learn the universe in under a minute a day. Sera is a short audio episode about space, picked for your sky tonight, with a quick question afterwards to make it stick. EVERY DAY, FREE Daily episode: One short audio episode each day, chosen around what's happening above you: clear skies, a full or new Moon, an upcoming eclipse. 48 free episodes: A library of under-a-minute audio episodes across the Moon, the Solar System, Deep Sky and Observation. All 48 stay free. Quick recall: Answer a short question after each episode, track your accuracy, and build a daily streak. NASA, made short: The Hubble feed and NASA's Astronomy Picture of the Day, rewritten into two or three plain sentences, linked to related episodes. 3D Solar System: Rotate, zoom and tap any planet for its facts and related episodes. Lunar calendar: Tonight's phase and illumination, the month ahead, the next four phases and upcoming eclipses with where they're visible. Astrophotography: A score for tonight's shooting conditions based on moonlight and cloud cover, with a suggestion for what to shoot. Built for the dark: A black, low-glare design that's easy on your night vision. SERA PRO - Every Pro episode, with new ones added regularly - Interactive deep dives: hands-on lessons where you move the Moon and predict its phases, starting with Moon Lab - Personal review: one short question at a time on what you've learned, spaced so it sticks - Offline: save episodes to listen and read without a connection SUBSCRIPTION DETAILS SERA PRO is an optional auto-renewing subscription, available yearly (with a free trial for eligible new subscribers) or monthly. The price in your currency is shown in the app before you buy. Payment is charged to your Apple Account at confirmation of purchase, or when the free trial ends. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings. Any unused part of a free trial is forfeited when you buy a subscription. Terms of Use: https://m1labs.io/terms/sera Privacy Policy: https://m1labs.io/privacy/sera

About

Introductory Physics Tutor

Features
Read full description

Introductory Physics Tutor helps students build connected understanding across a complete Physics I and Physics II learning path. Rather than treating physics as a collection of formulas to memorize, the app moves through a Learn → Practice → Master cycle. Focused teaching, worked reasoning, visual questions, immediate coaching, interactive models, adaptive review, and exam preparation work together to help students understand what a problem is asking and why a solution works. WHAT’S INCLUDED • 19 physics topics spanning mechanics, energy, momentum, rotation, fluids, oscillations, waves, thermodynamics, electricity, magnetism, optics, quantum physics, and nuclear physics • 67 focused skills organized into a connected course roadmap • 624 practice and mastery questions • 273 visual-reasoning questions • Immediate choice-specific coaching and retry-until-correct learning • 17 interactive Explore labs • Adaptive review that identifies weak skills and directs you to what to study next • Physics I, Physics II, and cumulative exam review • 60-question timed full exam simulation • Progress and mastery tracking across the course LEARN WITH CONTEXT Each focused skill begins with concise teaching and worked reasoning before practice. The goal is not simply to recognize the right equation, but to connect diagrams, physical models, units, signs, and assumptions to the underlying physics. PRACTICE VISUALLY Many questions use force diagrams, motion relationships, energy models, circuits, fields, waves, thermodynamic processes, and other visual representations. Feedback explains why an answer works and helps rule out common misconceptions. EXPLORE THE PHYSICS Interactive labs let you change variables, make predictions, observe what happens, and connect the result back to the governing model. Explore vectors, projectile motion, free-body diagrams, energy, collisions, torque, fluids, oscillations, waves, thermal physics, electric fields, capacitance, circuits, magnetism, optics, photons, and nuclear decay. REVIEW WHAT MATTERS Adaptive Review turns missed ideas into focused relearning and fresh checks. Exam Review provides guided Physics I, Physics II, and cumulative practice, while the full simulation offers an independent timed test experience. TRY THE REAL TUTOR FREE Topic 1, Measurement & Vectors, is fully available so you can experience the complete Learn → Practice → Master approach, including visual reasoning, progress tracking, and the Vector Components Lab. A single Full Access purchase unlocks the remaining course, labs, adaptive review, and exam-preparation features. No subscription is required. Designed for iPhone and iPad, with layouts built to take advantage of both devices.

Verdict

The call

Sera and Introductory Physics Tutor are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
