iPhone
A private space just for the two of you: posts, chat, reminders, a days-together counter and a cycle tracker your partner understands. Free, no ads.
SongKon is a private space for couples. Everything in the app is seen only by you and your partner.
Count your days together
• The home screen shows how many days you've been together and when the next anniversary is
• Tap “Miss you” and your partner gets a notification right away
Posts only the two of you see
• Post text, photos and places, and your partner is notified every time
• No likes, just “Seen by your partner” so you know they've read it
• Secret letters: write ahead and choose the day they can be opened
Chat and remind each other
• Open the chat right from the home screen, with read receipts
• Send your partner a reminder like “Don't forget the milk”, at a set time or every day
A cycle tracker your partner understands
• She records when her period starts; the app predicts the next one, the fertile window and ovulation day
• Tap a day in the calendar to see the estimated pregnancy chance
• Daily pill reminders
• She chooses whether her partner can see it: view only, no editing
Places we've been together
• Check in at cafés and trips and keep them on a map of your memories
Works solo too
• No partner yet, or want a private diary first? Everything works on your own
• Multiple accounts on one phone, with Face ID lock
Privacy
All data stays on your device and in your own iCloud, shared only with the partner you paired with. The developer has no server and can't access your data. No ads, no sign-up.
Cycle predictions and pregnancy chances are estimates based on what you record. They are not contraception and not medical advice.
Pairing needs two iPhones signed in to two different iCloud accounts.
