### 3/5 — Could be good but subscription… eh

*2026-03-19*

First, let’s be real, this app is a copy of Tydlig. Which is a calculator app that’s been around for years here (but hasn’t been updated in years. Still works great though). This app does include a few small new features, and the app works well, but unfortunately I can’t justify paying a recurring subscription for what I get from a one time purchase of Tydlig. If this was a one-time purchase… $5-7 or something like that, I’d buy it. But there’s no way I’d pay subscription for this. 

In fact, I suspect this app isn’t gonna take off if they keep this subscription model. Who’s gonna pay a subscription for this except professionals who do constant calculations, and those people generally already have more advanced tools for what they do, so I don’t see them paying for it either. I think the only target you can hit is the average user who needs it regularly but not frequently, and that user isn’t gonna wanna pay a subscription. (And again, this app is literally a clone of Tydlig with a few bells n whistles).
If you change it to one time purchase, I’d prob buy it. It works well.

**Developer response:** Thanks again for the thoughtful feedback. Based on feedback like yours, Calvance now offers two one-time purchase options—Local Pro and Local Unlimited—for local use. Premium subscriptions remain available for ongoing services such as multi-device sync. We appreciate your help in shaping a more flexible purchase model.
