> Useful little tools for everyday tasks, plus the PoshanSense food-journaling project.

Crop a photo. Convert a number. Get on with your day.

## Everyday tools

- [Image cropper and resizer](https://smallpotatostuff.in/tools/image-tools/): Crop exact pixels and resize locally. Images never leave the tab.
- [Currency converter](https://smallpotatostuff.in/tools/currency-converter/): Fetch the latest published ECB reference rates when you press Convert; not a bank quote.
- [Countdown timer](https://smallpotatostuff.in/tools/timer/): A quiet visual countdown; keep the tab open.
- [Signature PNG maker](https://smallpotatostuff.in/tools/signature/): Draw or import a signature locally and export a transparent PNG.
- [Unit converter](https://smallpotatostuff.in/tools/unit-converter/): Convert length, mass, volume and temperature; US and Imperial volumes are distinct.
- [Compass](https://smallpotatostuff.in/tools/compass/): A supported phone sensor is needed; not a professional navigation instrument.
- [Sound meter](https://smallpotatostuff.in/tools/sound-meter/): Rough uncalibrated sound estimates; not for hearing-safety decisions.
