I have been working on the latest update to my app: Wrote Myself a Letter which I finished after being laid off.
The idea is to send a letter to your future self, which I personally find very therapeutic in many ways, but what is important is the app is fully offline, has 0 tracking, ads or subscriptions. It's a once off purchase and own forever, which is something I wish was more common these days.
Check it out and, if for any reason you can't afford it just write me and I will send you a key.
