Compass

Read full description

Open the app and know exactly which way you're facing. Compass gives you a precise, calibrated digital compass with true heading, magnetic heading, and your exact bearing the instant the screen lights up. Most compass apps stop at a spinning needle. This one turns direction into something you can actually navigate with: drop a waypoint at your car or trailhead and follow a live needle back, read your coordinates and elevation off the screen, and check the sun's bearing when you have no signal at all. Everything runs on-device, fully offline. WHAT YOU GET - True north and magnetic north, corrected live with magnetic declination for your exact position - Your bearing in clean degrees and cardinal directions (N, NE, E...) that update the moment you turn - Saved waypoints with a live back-track needle that points you home, even with no signal - Live coordinates in decimal or DMS, plus elevation, so you always know where you stand - Sun bearing, altitude, sunrise, sunset and solar noon for orienting when the compass can't help - A built-in spirit level and inclinometer for checking level surfaces and measuring slope PERFECT FOR - Hikers and backpackers navigating trails and the backcountry - Boaters and paddlers holding a heading on open water - Travelers and explorers orienting in an unfamiliar city or landscape - Anyone who just wants to know which way is north, right now WHY NOT JUST USE THE BUILT-IN COMPASS The stock compass shows a heading and nothing else. It can't save the spot you started from, guide you back to it, show you where the sun will set, or double as a spirit level. Compass keeps all of that in one screen you can trust the moment you need it. PRIVACY Your location never leaves your device. No accounts, no ads, no tracking, ever. FULL ACCESS Compass and the spirit level are free to use. A subscription or one-time purchase unlocks the full toolkit: offline waypoint navigation and back-track guide, live coordinates, elevation and declination readouts, and the full sun and sky panel. Choose the plan that fits you: - Weekly - Yearly (best value) - Lifetime (one-time purchase, never expires) Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings. The Lifetime option is a single purchase with no renewal. Download Compass and always know your direction.

親戚が増えるほど、線が重なって誰が誰の子か分からなくなる。指が滑って違う人につないでしまっても、元に戻せない。家系図アプリでよく聞くその2つの困りごとに絞って作りました。 ■ 人数が増えても自動で整う 名前と続柄を入れるだけで、世代ごとに自動できれいに並びます。婚姻・養子・再婚・複数世代をまたぐ複雑な構成でも、線を自分で引き直す必要はありません。 ■ 間違えても、Undoで元に戻せます 誤って違う人とつないでしまっても、ボタン一つで元の状態に戻せます。「全部やり直すしかない」ということはありません。 ■ 実の親と、育ての親と。両方書けます 養子縁組があるご家庭でも、実親・養親の2組をそのまま記録できます。無理に1組にまとめる必要はありません。 ■ 作成・編集は人数無制限でずっと無料 何人分でも、何本の家系図でも、無料のまま作成・編集できます。広告も表示しません。 ■ 親族から届いたファイルも、そのまま追加できます 親戚が作った家系図ファイルを受け取ったら、新しい家系図として取り込めます。今お使いの家系図は変更されません(非破壊)。取り込みも無料です。 ■ 渡すとき・残すときだけ、買い切り¥600 ・ファイルとして書き出す:全体、または選んだ人より上の代だけを書き出して、親族に共有できます ・PDF出力:家紋を添えて、印刷して残せる形で書き出せます 一度の購入でずっと使えます。月額料金はありません。作成・編集・人数無制限・複数ツリーの保有・取り込みは、購入しなくてもすべて無料のまま使えます。 ■ データは端末の中だけに保存されます アカウント登録もログインも不要です。入力した内容は外部のサーバーに送信しません。日々の自動バックアップを保持し、書き込み中にアプリが落ちてもデータが壊れない設計にしています。 ■ こんな方に ・親戚の集まりで家系図を作ることになった方 ・以前ほかのアプリで作った家系図が、線が重なって読めなくなってしまった方 ・養子縁組や再婚があり、家族構成をそのまま記録したい方 ・誤操作で作り直しになるのが不安な方 ※ 生年月日は「昭和10年頃」のような自由な書き方にも対応しています。正確な日付が分からない先祖の記録にもお使いいただけます。
