Express yourself in the most authentic and therapeutic way, using letters! WriteBack is a new way to get in touch with your friends and family. 1. Make a scribble for whatβs in your heart and save it as a journal. 2. Share your thoughts with your loved ones as a personal letter. 3. Track the responses and write back again. 4. Send the letters to your contacts. 5. All the letters are privately shared and not public. Letters can be seen only by the recipient, you choose! 6. Save the letters in one place, and track their corresponding responses in one place. Just like email threads, WriteBack makes a thread of letters so you can find them easily! Enjoy writing!
Sorra
Read full descriptionHide full description
Sorra is a calm space to send a message without being directly identified to the recipient β and to receive human surprises from someone you donβt know. It isnβt for endless βchatβ with the same person, but for a moment of connection: one sentence, one idea, one greeting β something honest between two strangers. How it works Write your message within the set limits and send it βquietlyβ β the system delivers it to a random user. You donβt choose who they are; the recipient doesnβt see your name the way they would on classic social networks. The same idea applies when you receive messages: something kind, unexpected, or simply human may arrive from someone else. Why Sorra Less pressure β no focus on photos, follows, or vanity metrics. More sincerity β one message, one moment. Your profile β you can personalize your experience (e.g. name and profile photo) without turning sending into an βopenβ social network. Notifications β you can be notified when a new message arrives. Message quota β to keep the community balanced; you can have free messages on a schedule and options to buy more when you need them. Care Sorra is meant for respectful communication. Do not send offensive, threatening, sexual, or illegal content. Users who break the rules may be reported or removed. If you want a place to write a thought without putting yourself on display, or to read a line from a stranger β Sorra is for you.

Verdict
The clearest difference is in-app purchases: WriteBack at none against Sorra's 1. WriteBack also leads on iOS requirement (13.0 vs 18.0). Sorra's advantage is update cadence (every 2 days vs every 5 days). On price, ads and device support there is nothing between them.
