A digital temperature log for cafés, delis, food trucks, and small kitchens. Log your fridge, freezer, and hot-hold checks in a few seconds, get flagged automatically when a reading is out of range, and export an inspection-ready PDF when someone asks for your records.
Download on the App Store — free with unlimited logging. No account, no subscription.
If you run a food business, you already know the drill: fridge, freezer, and hot-hold temperatures need to be written down every day, in a form you can hand an inspector without digging through old notebooks. Most places still do this on a paper sheet taped to the fridge door. It works right up until the sheet gets greasy, the pen disappears, or the inspector asks for last March.
This app does one job. It replaces the paper sheet with something faster, and it turns your history into a clean PDF on demand. It is not a full HACCP management suite with checklists for everything, and it doesn’t try to be. If you want the fastest way to log temperatures and stay inspection-ready, this is it.
Paper is fine until it isn’t. Some honest reasons kitchens switch:
What paper still has going for it: it never runs out of battery and anyone can use it. That’s why the app copies the paper workflow instead of reinventing it. If your staff can fill in a sheet, they can use this.
If you’re wondering what temperatures you should actually be logging, here’s the short version. Always confirm against your local regulator’s guidance, since exact requirements vary by country and sometimes by state or local authority.
| Unit | Common guideline | What you’re avoiding |
|---|---|---|
| Fridge | At or below 5°C (41°F) is the widely used target for chilled storage. | Bacteria multiplying in perishable food held too warm. |
| Freezer | Around -18°C (0°F) is the common standard for frozen storage. | Partial thawing and quality loss, plus growth if food warms enough. |
| Hot-hold | Food kept hot for service has a regulated minimum: 63°C in the UK, 135°F (57.2°C) in the US. Other regions differ. | Cooked food sitting in the temperature danger zone. |
The core idea behind all of it is the danger zone: the band between roughly fridge-cold and hot-hold-hot where bacteria grow fastest. Cold storage keeps food below it, hot-holding keeps food above it, and your log is the evidence that you checked. Most regulators expect checks at least daily, and many businesses log morning and evening.
This is general information, not food safety advice for your specific business. Your local environmental health officer or health department has the numbers that apply to you.
Temperature records are one part of a HACCP-based food safety system, usually the part that generates the most paperwork. This app covers that part: it’s a HACCP-friendly temperature log, not a complete HACCP plan builder. If you already have your plan (or use something like Safer Food, Better Business in the UK), this slots in as the daily temperature diary. If you need cleaning schedules, delivery checks, and full checklist management, you want a bigger tool — this one is built to be the fastest at the thing you do every single day.
Logging is free, forever, with no limits. Log ten units a day for years and pay nothing.

Where is my data stored? On your device only. Your readings, staff names, and business details never leave your phone except when you choose to share an exported PDF yourself.
How do I restore my purchase after reinstalling or switching devices? Open the app, go to the Export tab, open the unlock screen, and tap “Restore purchases.”
How do I export a PDF? From the Export tab, tap “Export PDF.” Logging is always free and unlimited — the one-time purchase unlocks full PDF export instead of the single-entry sample.
Does it need an internet connection? No. Everything works offline, including PDF export. Your records live on your device.
Will an inspector accept a digital log? Digital records are widely accepted; what inspectors care about is that checks were actually done and recorded consistently. If you’re unsure, ask your inspector, but in practice a clean digital log tends to go over better than a smudged sheet.
