I made an International calling app after Skype shutdown ($0.01/min)

I built CallSky as a simple alternative for international calling after Microsoft shut down Skype earlier this month. The app lets you make calls to landlines and cell phones worldwide starting at $0.01/minute with a pay-as-you-go model. I noticed that while Teams replaced Skype's video/chat conferencing, it doesn't offer the same affordable PSTN calling that many people relied on. WhatsApp and other messaging apps don't solve this - whether you're an expat calling the IRS for taxes, reaching elderly family members who don't use smartphones, or contacting people in areas with…

What it does

In the maker’s words, at launch

I built CallSky as a simple alternative for international calling after Microsoft shut down Skype earlier this month. The app lets you make calls to landlines and cell phones worldwide starting at $0.01/minute with a pay-as-you-go model. I noticed that while Teams replaced Skype's video/chat conferencing, it doesn't offer the same affordable PSTN calling that many people relied on. WhatsApp and other messaging apps don't solve this - whether you're an expat calling the IRS for taxes, reaching elderly family members who don't use smartphones, or contacting people in areas with limited internet infrastructure, you still need traditional phone calls to landlines and mobile numbers. So I built this focused solution using Swift/UIKit for iOS with Supabase handling the backend. The app has been live for about 10 days with 49 in-app purchases so far. There's clearly interest from users, but discoverability remains extremely challenging without a significant marketing budget. Currently iOS-only with Android in development.

  • Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

    Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
