Opening your saved planner…
Nothing has been overwritten. Keep a copy of the saved data. A lost encryption password cannot be reset.
Repeat the last shift as a draft, or prepare this week from a rota. Confirm each entry before saving.
Forecasts use unpaid expected income and bill dates. They cannot guarantee a bill is covered. Enter an available opening balance as of today to see a running estimate. Today’s receipts and bills must already be reflected in that balance.
Enter monthly amounts. Divide annual bills by 12. Keep work-related business costs in work records to avoid double counting.
Compare your recorded earnings with the gross pay and hours printed on a payslip. This is a comparison, not tax calculation or proof of an employer error. Exclude jobs or dates that are not on that payslip.
Record the actual amount received against an earnings entry below. Part payments stay outstanding until you mark the entry settled. Receipts are separate from earned income.
Free, rule-based help. No AI model, API account or cloud processing. Use the examples below. Nothing is sent to an AI provider.
Messages and live shifts use this device’s clock and time zone. A running shift is saved on this device and continues while the app is closed. Correct the phone’s clock if it is wrong. No contacts or location permission is used.
“On my way” asks whether paid work starts now, so travel is not silently counted. Finish times include the date, so overnight shifts work. Unpaid breaks are entered before saving.
Voice converts speech to text only where verified on-device recognition is available. Otherwise use typing or your phone keyboard’s microphone. Keyboard dictation may require internet. The app does not interpret uploaded audio recordings.
Your start and finish timestamps have been captured. Confirm the pay details below.
The proposed entry is ready for review.
Should paid work start at the message timestamp?
These checks run when you open or use the app. They are not background push notifications.
Read the complete step-by-step guide, including pay bands, shifts, payments, backups and troubleshooting.
Add hourly, daily / gig or fixed pay jobs. Rates are copied into new entries, so changing a default never rewrites previous pay.
Optional password protection encrypts this installation’s saved planner records. Your password cannot be recovered. Keep an encrypted backup and your password somewhere safe. This is not Face ID or fingerprint locking.
When encryption is enabled, the app locks after five minutes without interaction, including time spent in the background. The timer continues. Device screen locking is still recommended. CSV exports are unencrypted.
On iPhone, choose Save to Files when the share sheet appears. A share or download prompt cannot prove that you saved the file: restore-test the file before clearing data.
Records stay in this browser on this device. Export a backup regularly and before moving phones or clearing browser data.
The file is validated before restore. Replacing data requires confirmation. Export your current records first.
