Turn focused time into colorful gems. Gems stay when you take a day off. English and Japanese UI; support is currently provided in Japanese. FOCUS BY ACTIVITY Choose an activity and a free 25-, 45-, 60-, or 90-minute timer. Each completed minute adds 10 grams to your jar. • Tap a gem to bounce it; long-press for details. Tilt your iPhone to move gems • Vivid crystals reflect the colors in their breakdown • Vertical menus and smoother returns from landscape timers to the portrait jar • Every 250 minutes forms a crystal; ten form the next size. Remaining time carries forward • Weekly and lifetime progress, milestones, and manual records separate from timed focus • Share images and short GIFs of eligible records, with PomoGem branding and its website MUSIC FOR EACH ACTIVITY Set music and autoplay per activity using suggestions, your playlists, Apple Music search, or a shared link. Save choices in the activity editor. Music settings stay on this iPhone. Autoplay respects audio already playing. Playback uses the Music app; streaming music requires an Apple Music subscription. OPTIONAL SCREEN TIME GEMS In Settings > Add App Time, choose apps and an activity for each. Apps with the same activity combine their use: each confirmed 10 minutes adds a 100-gram gem. Activities count separately. Free: 5 apps; Pro: unlimited. OS notifications may be delayed. Periods under 10 minutes are not added. Gem recording pauses during focus timers. Apps you want to use less can add black gems every combined 10 minutes. This selection is unlimited for everyone. Black gems combine only with black gems; they never count toward study time, mass, rewards, or sharing, or subtract earned gems. An app cannot belong to both selections. Authorization and recording are optional. POMOGEM PRO A one-time In-App Purchase adds custom timers from 1:00 to 360:00 and unlimited Screen Time learning apps. Enter minutes and seconds or use wheels. Update both devices to hand off second-level timers. Pro has no subscription, trial, or renewal. The purchase screen shows your price. Time-based crystals no longer offer Pro month stamps. Session dates, monthly records, and your purchase remain intact. YOUR STORAGE CHOICE At first launch, choose private iCloud sync or this iPhone only. Device-only mode works without an Apple Account or network and never uploads automatically. If you confirm iCloud, activity names, achievement notes, records, settings, and the active timer use your Apple Account's private CloudKit storage. Initial loading and resuming sync require online checks. An eligible, previously verified local copy can be used offline in iCloud mode; changes wait on this iPhone for sync. Verified account changes or conflicting history can block access to protect data. Reopening the app may be required. A connection check does not prove all records have uploaded. Settings lets you enable iCloud using its data to replace device-only records, or disable it by copying verified data to this iPhone while retaining iCloud data. In iCloud mode, you may also preview the cloud contents and explicitly confirm replacing this device's data, including unsent changes. Histories are not merged. Replacing all iCloud data with device data remains unavailable. Transfers require a connection and restarts as instructed. Do not uninstall during a transfer. Uninstalling loses device-only records and unsent changes. Exported JSON cannot be reimported for restoration or migration. Screen Time app selections, pending thresholds, and black gems stay on this iPhone and are excluded from JSON export and storage transfers. Imported learning records follow your chosen storage, including private iCloud sync, but are excluded from shared images, GIFs, captions, and JSON export. Unverified summaries are excluded from sharing and export. Diagnostics stay on-device without app tokens or gem counts. No advertising, tracking, analytics SDK, or developer server.
