Log your hours, let Flex 40 work out the overtime your employer should be paying, and catch the paychecks that come up short — before it quietly becomes normal.



Most time apps stop at counting hours. Flex 40 keeps going — it works out what that time is worth, then holds it against what actually landed in your account.
A guided setup walks you through your hourly rate, overtime rules, pay frequency and tax profile. Eight questions, once.
Hit Start Shift, or enter hours after the fact. Tag overtime or a call-out, add breaks, miles, a case number or notes.

Regular, overtime and double-time hours priced out for the pay period, with tax and deductions taken off for a net estimate.
Log what you were actually paid. Flex 40 flags underpayments and shows you exactly where the two numbers diverge.

Overtime isn't one rule, it's a stack of them — and the order matters. Paid leave is the part most calculators get wrong: it's paid time, so it counts toward your pay, but it isn't worked time, so it must never push you over an overtime threshold.

Every pay period gets a summary you can actually argue from — not a vague weekly total.

Year-to-date gross, what share came from overtime, what tax took, and what landed in your pocket.
Bank overtime instead of cashing it, at your accrual rate. Set a cap and overflow pays out as cash — automatic or decided hour by hour.
Vacation, sick, holiday, comp time used and other paid leave — each paid correctly and each kept out of your overtime math.
Log miles against any entry, save preset routes you drive often, and get mileage analytics alongside your hours.
Turn a pay period into an invoice, or export raw entries to CSV. Useful whether you're checking a paycheck or billing a client.
Achievements tied to hours logged, earnings, streaks and overtime records — because the habit is what makes the data worth anything.
Your records live on your device, so you own the backups. Export a copy whenever you like and restore it on a new phone.
No account. No cloud. No sign-up.
Your hours, pay rates, tax profile and every paycheck you log are stored in a database on your phone and nowhere else. There is no Flex 40 server holding your wages, because there is no Flex 40 account. Nothing to breach, nothing to sell, nothing to log into.
Read the privacy policyEverything you need to log time is free, forever. Pro unlocks the pay engine, the reports and the verification tools — for a single payment, not a subscription that outlives your interest in it.
No monthly fee, no annual renewal, no hidden charges. Every feature Flex 40 ships from here on is included — yours for life.
Set up your rates once, log your shifts as you work them, and let Flex 40 tell you the number your employer owes you.
