Focus, and a planet forms. Stay until the timer ends and it joins your galaxy. Quit early and it scatters. A pomodoro focus timer that turns your time into worlds. Made with ADHD and restless focus in mind, Planeta gives every study block, homework hour or deep work sprint a reward you can actually see. HOW IT WORKS 1. Pick a session length from 5 to 120 minutes and start the timer. 2. While the clock counts down, your planet's terrain and colors take shape. 3. When time is up, the planet is yours and joins your galaxy. The rule is simple: stay to the end and you keep what you built. Leave early and nothing is left behind. It's an easy way to stick with the pomodoro technique, one session at a time. NO TWO ARE EVER ALIKE Every session generates a new terrain, color palette and set of rings. There are 20 planet types to discover, and no two planets ever come out the same. LONGER FOCUS, RICHER PLANETS Focus for more than 30 minutes and your planet gains an atmosphere. Go past 60 minutes and it gains a ring. Shorter sessions still leave a planet, just without the extra layers. That's a small reason to stay in flow a little longer. YOUR GALAXY The planets you earn settle into star systems. Pan across the map and see which session each planet came from. Your focus history becomes a place you can explore. THE CODEX A record of all 20 planet types that fills in as you discover each one. JOURNAL Every voyage is logged with its length, its tag and its planet. Add a note to any session so you remember what you worked on. It doubles as a simple study tracker for ADHD study habits, exam prep or long work days.

Grotto
Read full descriptionHide full description
Grotto turns intentional phone use into a place you can enter. Create up to nine local Spaces and choose apps through Apple's private Screen Time picker. Several Spaces can be active together. Each hides its own selected apps; leaving one keeps apps hidden if another active Space still includes them. Choose how each Space works: - PIN: enter with a tap and leave with your six-digit PIN. - Countdown: start a one-time session from 30 minutes to 12 hours, in 30-minute steps. Use your PIN to leave early. - Location: automatically enter and leave this Space around its own 500-metre area. Choose its place on a map or use your current location. Different Spaces can use the same place or different places. Location automation requires Always and Precise Location access. Map selection itself does not request your current location. iOS may delay automatic arrival, departure, or countdown completion; these are not exact-time alarms. After a restart, unlock your device before automation can resume. Each Space has a handcrafted 2D environment. Moss Haven is included. Optional one-time purchases unlock additional illustrated environments, interactions, ambience, and visual progression. All nine Space configurations, all three modes, and recovery controls remain available without payment. Privacy by design: - App choices use opaque Apple system tokens. - Grotto stores Space settings locally and does not upload your places or record a movement history. - Apple Maps loads map data online and may send map-display requests to Apple. - No Grotto account, analytics, advertising, or tracking. - Sensitive management screens are covered in the app switcher. Grotto is for adults managing their own device. Your Space PIN protects manual exit, editing, and deletion. You can revoke Screen Time authorization in iOS Settings. Grotto cannot prevent the device owner from changing system settings or uninstalling the app.
