Learn to Write: Alphabet Glow is a fun and interactive way for kids to learn handwriting while exploring glowing neon letters full of life and animations! Designed for preschool and kindergarten learners, this app makes tracing the alphabet an exciting adventure. Each letter has 3 magical steps with unique effects, objects, and rewards — keeping children engaged and motivated to practice writing again and again. * How it Works Step 1 – Build the Road: Drag along the glowing path to create roads, tracks, and rocket trails. When completed, the letter comes alive with animations — trains drive across “A,” cars race through “B,” rockets launch in “C,” and more! Step 2 – Discover and Play: Trace the letter again to place fun objects that match the letter (A = Apples, B = Balls, C = Cars…). Kids can tap and interact with the objects after finishing the letter. Step 3 – Meet the Character: Complete the final trace by guiding glowing bees! Each letter reveals its own unique animated character — like a Drum for D, a Carrot for C, or an Apple friend for A. * Rewards & Progress Earn 1 star for every step completed. Collect stars for each letter and see your progress in the main lobby. Keep practicing to unlock all 3 stars per letter! * Key Features Neon glow design that makes tracing letters exciting and fun Interactive animations for every letter Unique characters to discover and collect Star rewards system that motivates kids to keep learning Perfect for preschool & kindergarten handwriting practice Safe for kids: no ads, parental gate for in-app purchases Learn to Write: Alphabet Glow transforms handwriting into an adventure of light, color, and imagination — the perfect way to introduce your child to ABC learning!

Planet Explorer

Take a survey craft anywhere in the solar system. Twenty-four worlds — the Sun, all eight planets, five dwarf planets and ten famous moons — and not one of them is a photograph. Every surface is generated on your device as you arrive: Jupiter's counter-flowing cloud bands with the Great Red Spot drifting between them, Saturn's stripes under real ring gaps, Io's volcanoes, Europa's cracked ice, Haumea tumbling end over end. TWELVE SURVEY MISSIONS Each mission is a clue rather than a waypoint. "Find the moon that orbits its planet backwards." Work out which world it means, fly there, descend close and hold position to survey it. Every debrief is a real fact, and your badges are saved. REAL RELIEF, REAL PLACES Solid worlds carry a height map, so craters have raised rims and Valles Marineris is genuinely a gash four thousand kilometres long — visible on the planet's silhouette and sharpest along the terminator. Turn on landmarks and the real places name themselves at their real coordinates: Olympus Mons, Tycho, the Sea of Tranquility where Apollo 11 landed, Caloris, Sputnik Planitia, the Cassini Division. Worlds we have only ever seen as cloud, like Venus, honestly have nothing to show. THE VIEW FROM A MOON Select a moon and its planet hangs in its sky — Saturn looming over Enceladus, Jupiter's bands churning above Io, Earth floating over the Moon with its clouds still moving. The sky moves too: the planet circles at the moon's real orbital direction and waxes through phases. Every moon is tidally locked, so the host stays over the same face, and Pluto and Charon each keep one face toward the other, as they really do. TIME WARP One second of flight is six minutes of local day on every world. Speed that up to sixty times and the physics becomes something you can watch: the terminator sweeping across the ground, Haumea turning end over end every four hours while Venus barely creeps. SCIENCE LAYERS One tap draws the schematic — spin axis with the poles marked and the real axial tilt, the equator, the direction of rotation, the sub-solar point and the terminator. Uranus lying on its side at 98°, Venus upside down at 177° so its spin runs backwards, Triton turning against its own orbit: things to see rather than take on trust. A SENSE OF SCALE The target and Earth drawn at one scale, which is the point — next to the Sun, Earth is a dot you have to hunt for. Then the whole solar system shrinks until the Sun is a 30 cm beach ball, Earth a peppercorn 32 metres away, Neptune a marble most of a kilometre off. Distances are measured in things that take time: how long sunlight takes to arrive, how long a radio call would take, how many years an airliner would need. YOU, HERE Enter your weight and age and every world tells you what you would weigh there and how high you could jump — 35 metres on Enceladus — from real surface gravity. BUILT TO BE HARMLESS No advertising. No in-app purchases. No accounts. No analytics. No network requests of any kind, so it works in a tunnel or on a plane. Nothing is collected, and nothing can be: the app has no networking code in it at all. Every number, every clue and every debrief is real science, written to be read by someone young.

Verdict

The call

The clearest difference is in-app purchases: Planet Explorer at none against Learn to Write's 1. Learn to Write's advantage is iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
