YOUR RECORDS NEVER LEAVE YOUR PHONE
• Everything is stored on your device and encrypted at rest — no cloud, no account, no login
• No subscription and no risk of an update wiping your work
• Export to PDF any time: email it, print it, or save it wherever you like
• Your existing records and PDF export stay free forever

LANDLORD GAS SAFETY RECORDS DONE RIGHT
• Every information item required by regulation 36(3)(c) of the Gas Safety (Installation and Use) Regulations 1998
• Per-appliance safety checks: flue condition and performance, ventilation, operating pressure or heat input, safety devices — and a clear safe-to-use outcome
• The next check date follows the MOT-style rule in regulation 36A: check within the last two months of the current deadline and the app keeps your renewal date instead of quietly shortening it
• Re-check a property in seconds: duplicate last year's record and update what changed — your data is never held hostage

WARNING NOTICES TO THE CURRENT STANDARD
• Immediately Dangerous (ID) and At Risk (AR) classifications per the current industry procedure — the decision is always yours, with the definitions on screen
• Records who was advised, what was disconnected, and signature or refusal
• RIDDOR prompt: flags when a situation may be reportable, with the 14-day window

BOILER SERVICE RECORDS
• A clean service record for annual boiler and appliance servicing — readings, work done, parts fitted

BUILT FOR THE FIELD
• Sign on screen with your finger
• Optional PIN and fingerprint lock for the app
• Big controls, works with no signal in a basement or plant room

ONE-TIME PURCHASE
The free version lets you create your first three records. A single one-time purchase unlocks unlimited records. No subscription. No ads. Ever.
