For small businesses
The everyday tools a spreadsheet was never quite right for.
Staff roster
Build me a staff roster app. Let me add my team members, then create a weekly schedule of shifts with a day, start and end time, and role. Show the week in a grid, let me mark shifts as confirmed or open, give each person a view of just their own shifts, and keep a running total of hours per person for the week.
Stocktake & inventory
Build me a stocktake app for my workshop. Let me add products with a name, SKU, category, quantity on hand, and reorder level. I want to search and filter the list, adjust quantities up or down with a note, and highlight anything below its reorder level. Show a simple dashboard of total items and how many are low on stock.
Quote calculator
Build me a quote calculator for my trade business. Let me pick services from a list (each with a base rate), add materials with quantities and prices, apply a margin percentage, and add tax. Produce a clean, printable quote total I can send a customer, and save each quote against a customer name and date so I can find it later.
Job & work-order tracker
Build me a job tracker for my two-van business. Each job has a customer, address, description, assigned person, scheduled date, and a status (booked, in progress, done, invoiced). Let me see today's jobs, filter by person or status, and add notes and photos to a job as it progresses.
Simple CRM
Build me a simple CRM for my regulars. Let me store customers with their contact details, notes, and a history of jobs or orders. Let me tag customers, search them, and see who I haven't heard from in a while so I can follow up.
Booking sheet
Build me an appointment booking sheet. Let me set my available days and time slots, then book customers into slots with their name, contact, and the service. Show the day and week at a glance, stop double-bookings, and let me mark a booking as confirmed, arrived, or a no-show.
Timesheets
Build me a timesheet app my team fills in on their phones. Let each person clock in and out against a job or task, add a note, and see their hours for the day and week. Give me a manager view that totals hours per person and per job, and lets me export a week.
Daily takings log
Build me a daily takings log for my café. At close, let me record cash, card, and other takings, plus a note. Show a running total for the week and month, a simple chart of daily takings, and let me compare this week to last.
For freelancers & the self-employed
The back office you keep meaning to sort out.
Invoice tracker
Build me an invoice tracker. Let me record invoices with a client, invoice number, amount, date sent, and due date, and mark each as draft, sent, paid, or overdue. Show totals for outstanding and paid this month, and automatically flag anything past its due date.
Client pipeline
Build me a client pipeline to track work from lead to paid. Each deal has a client, description, value, and stage (lead, quoted, won, in progress, invoiced, paid). Show it as a board I can drag cards across, with a total value per stage, and a note history on each deal.
Time tracker per client
Build me a time tracker for my client work. Let me start and stop a timer against a client and task, or add time manually, and jot a note. Show hours by client and by day, this week's total, and let me mark entries as billed so I know what's left to invoice.
Client portal
Build me a simple client portal I can share with the people I work with. Each client should see only their own projects, files, and a status update from me, and be able to leave a comment or approve a deliverable. Keep everything else private to me.
Expense log for tax
Build me an expense log ready for tax time. Let me record expenses with a date, amount, category, and a photo of the receipt, and flag which are claimable. Show totals per category and per month, and let me export a date range for my accountant.
Proposal builder
Build me a proposal builder. Let me assemble a proposal from reusable sections (intro, scope, timeline, price), fill in the client details, and produce a clean, shareable page or PDF. Save each proposal and track whether it's been sent, viewed, or accepted.
Content calendar
Build me a content calendar. Let me plan posts with a title, channel, status (idea, drafting, scheduled, published), and publish date, and see them on a month view. Let me filter by channel and keep the draft text and any links with each post.
Financial models & spreadsheets
The spreadsheets you rebuild every year — turned into apps that just work.
Cash-flow forecast
Build me a 12-month cash-flow forecast app. Let me set an opening balance, then add recurring and one-off income and expenses by month. Calculate the running monthly and closing balance, show a chart of the balance over time, and let me tweak any figure and watch the forecast update. It's replacing a spreadsheet, so make editing quick.
Budget vs actual
Build me a budget-vs-actual tracker. Let me set a monthly budget per category, then log actual transactions against those categories. Show budget, actual, and the difference per category and overall, with over-budget categories highlighted, and let me switch between months.
Pricing & margin calculator
Build me a pricing and margin calculator. Let me enter a product's cost, target margin, and any fees to get the selling price — or enter a price and see the margin. Save products so I can compare them in a table and spot which ones aren't pulling their weight.
Break-even calculator
Build me a break-even calculator. Let me enter fixed costs, price per unit, and variable cost per unit, and show how many units I need to sell to break even, with a simple chart of profit as sales grow. Let me save a few scenarios side by side.
Simple profit & loss
Build me a simple profit-and-loss app. Let me enter income and expenses by category and month, and it works out gross profit, total expenses, and net profit per month and for the year. Show a clean summary and let me compare two periods.
Savings goal tracker
Build me a savings goal tracker. Let me create goals with a target amount and date, log contributions, and see progress bars, how much is left, and whether I'm on track for the date. Let me share a goal with my partner so we both update it.
Recurring revenue (MRR) tracker
Build me a recurring revenue tracker. Let me add customers with a plan and monthly amount, mark them active, paused, or churned, and see total MRR, new vs churned this month, and a chart of MRR over time.
Loan repayment calculator
Build me a loan repayment calculator. Let me enter the amount, interest rate, and term, and show the monthly repayment, total interest, and a full amortisation schedule I can scroll. Let me compare two loans side by side.
For families & home
The stuff that lives on the fridge — but better, and shared with just your family.
Weekly meal planner
Build me a weekly meal planner for my family. Let me plan breakfast, lunch, and dinner for each day, pick from a list of saved meals or add new ones, and generate a shopping list from the week's plan. The whole family should be able to see the current week.
Chore chart & pocket money
Build me a chore chart with pocket money for my kids. Let me add each child and a list of chores with a point or dollar value, let the kids tick off chores they've done, and total what each has earned this week. Let me approve completed chores before they count.
Shared shopping list
Build me a shared shopping list the whole family can add to. Let anyone add items with a quantity and category, tick them off in the shop, and keep a list of usual items I can re-add in one tap. Group the list by aisle to make shopping faster.
Sports & activity schedule
Build me a family sports and activity schedule. Let me add each child's activities with the day, time, place, and who's on pick-up and drop-off, and show the week so we can see clashes. Let everyone in the family view it and get this week at a glance.
Household bills
Build me a household bills tracker. Let me add bills with an amount, due date, and who's paying, mark them paid, and see what's coming up. Add a who-paid-what tally so my partner and I can square up fairly each month.
Holiday planner
Build me a family holiday planner. Let me keep the itinerary by day, a shared packing checklist everyone can tick, a list of bookings with confirmation numbers, and a budget with what we've spent so far. Let the whole family see it on their phones.
