### 5/5 — Does What It Says On The Tin

*2026-06-17*

Simple. Straightforward. Ad free. No data collection. The only desired ideas would be having it default to the numeric keyboard, a setting to default to either C to F or F to C at startup, and having a way to quickly clear the slate when you go back to do another conversion, rather than having to get the cursor in the right place and tapping Delete to get rid of your previous input. But glad I found this!

**Developer response:** Good idea. I have incorporated those suggestions in version 2.1, which should be out in a couple days.

### 5/5 — Easy and clean

Great app. No frills and no data collection. I think the developer needs to add a tip jar.
