公開日 26 June 2026更新日 8 August 2026約3分執筆 someday

Somedayは、TikTokやInstagramで見つけた場所を保存するための無料iOSアプリです。地図アプリではなく、非公開コレクションで管理できます。Somedayアプリ / Someday map検索の公式サイトです。

If you searched for Someday app or Someday map — this is the official site for the iPhone app at gosomeday.app.

someday is a place memory app: it helps you save and organise spots you discover on TikTok, Instagram, DMs, map links, screenshots, and notes into private collections you can actually find later.

It is not a standalone map or navigation app.

What problem someday solves

Discovery happens on social. Memory does not.

You find a rooftop bar on TikTok, a cafe in an Instagram reel, or a restaurant recommendation in a DM. You tell yourself you will remember it. A week later, the place is gone from your head — and buried in a feed you will never scroll back through.

someday closes that gap by keeping each place with its context attached:

Who sent it or recommended it
What to order or do there
Which trip or mood it belongs to
Why it caught your attention in the first place

How someday is different from maps and social saves

Google Maps saves are built for location. They struggle when your places come from reels, DMs, and group chats with rich context attached.

TikTok and Instagram saves are built for rediscovery inside those apps. They are weak when you need a organised list for a real trip or dinner plan.

someday sits in the middle: social discovery in, organised place collections out.

What you can save

Restaurants, cafes, bars, and bakeries
Viewpoints, hikes, and weekend getaways
Hotels, shops, and local favourites
Anything you discover online that you want to remember with context

Import via the iOS share sheet from TikTok, Instagram, map links, and more.

How it works

Share a post or reel into someday from the iOS share sheet.
Add to a collection — trip ideas, date nights, neighbourhood hits.
Keep notes while the context is still fresh.
Return when it is time to plan, visit, or share a shortlist.

Free vs Pro

The free tier includes monthly import limits (link, notes, and screenshot imports). Manual adds to collections remain free. Manual adds to collections remain free. Download on the App Store.
