Review intelligence
Medium confidenceUsers find the app easy to use for sending letters quickly, but some report delivery issues and high costs.
Best 60 dollars I’ve ever spent, this app makes it so so so easy and I can use emojis in the letters which is a huge plus for me. Sends super fast and the customer service is great if you ever have issues!
I purchased 20 letters. I have sent 5 but the app says I sent 15 and have 7 left. Scam alert

Questions this record can answer
How was every figure on this page produced?
Each figure is read from public App Store metadata or computed from it, dated to when we read it, and traceable to a stored row. Percentiles, cadence, longevity and sentiment are derived by us; ratings, prices, sizes and dates are taken as the store reports them.
Why can the star average and recent opinion disagree?
The star average is cumulative over the app’s whole life, so recent opinion barely moves it. Any sentiment figure we compute reads only recent review text, which is why it turns first. Treat a divergence as an early indicator, not a verdict.
What can this page not tell you?
Downloads, revenue, active users, subscription pricing inside the app, and anything about security or data handling. None of those are visible in public store metadata, so we do not estimate them.
