## Pendulum Description
Pendulum - keep track of your pen pals!

• Add your friends, record when you send them letters or they send something to you. See how long it takes for your letters to arrive!
• Record what pen, ink, and paper you used to write to each person, to keep the variety going each time you write.
• Reminders to write back, or to post letters you've written but have sat by the front door for ages; you won't forget to stay in touch again.
• Sync via iCloud, so you can keep up to date regardless of what device you have to hand.

## Pendulum Reviews in United States

### ***** "Easy to use"
Super clean and easy to use. Love it.
-- zeldagirl13, 2025-04-24

### **--- "Interesting but unwieldy"
The app has potential, but it isn’t intuitive and is a bit unwieldy. It’s frustrating not to be able to add addresses and I will not link things to my address book. It isn’t clear how to delete things and on a few records I ended up with very confusing notes on whether I’d sent a letter or not. It’s nice to be able to add pics of letters. All in all, pen and paper work better for me.
-- Sad news, 2024-11-17

### ****- "Love this app"
Makes keeping track of my penpal so much easier.  One thing I would change if I could is to have a place for peoples addresses if you don’t use your contact list.  I don’t want to add all my penpals to my normal contact list so I have to keep addresses on paper.

Overall, absolutely love this app
-- Kskev, 2023-11-18

### *---- "Erased my progress"
I spent hours putting my penpals into this app. The WHOLE time it either made duplicates of stuff I made or removed them! It’s so annoying! I finally spent hours getting everything in and when I reopen app, half my stuff is gone?! WHAT! WOULD NOT RECOMMEND IF YOU WANT UNSTABLE APP!
-- Asiankat, 2023-05-18

### ***** "Amazing App for PenPals!"
I thought I’d give this app a try since I basically just have a spreadsheet to track things and it’s been amazing! It tells you exactly when you sent mail, how many days it’s been since you received mail, etc… Been such help keeping all my correspondences organized. And you can add pictures of your pen pals for their profile and also any past letters you’ve sent so you can reference them!
