What is Spanner?

Spanner builds small apps for your everyday life

Spanner is a simple way to get a personal app made just for you—without you having to design anything. You tell Spanner what you want to do, and it creates an app you can use anytime.

Think of it like asking for a tool and getting it instantly—built around your routine.

How it works (the simple version)

You describe what you need (for example: “a grocery list that remembers my usual items”).
Spanner creates a personal app that matches your request.
You use it whenever you need it—to add items, track progress, or repeat a task the same way every time.

In Spanner, an “App” usually means a small, focused tool for one job—like a list, tracker, or helper—not a big all-in-one system.

What you can make with Spanner

Spanner is best for things you do repeatedly and want to keep organized. Here are a few common examples:

Lists

Grocery list (with categories like produce, dairy, pantry)
Packing list (with “already packed” checkboxes)
Shared household to-do list

Trackers

Habit tracker (streaks, notes, quick check-ins)
Symptom or mood tracker (simple entries you can review later)
Expense tracker (amount, category, optional notes)

Helpers for repeated tasks

Morning routine checklist
Meal planning helper (ideas, favorites, notes)
Workout log (sets, reps, how it felt)

If you can describe it as “I want a simple way to…” then it’s a great fit for Spanner.

What makes a Spanner App different

Spanner Apps are designed to be:

Personal: built around how you actually do the task.
Focused: usually one main job, so it’s fast to use.
Flexible: if something isn’t quite right, you can ask for changes later.

Real-world examples (in everyday language)

You want: a grocery list that’s easy to check off while shopping.

Spanner can create: a list with sections (Produce, Meat, Pantry), a quick add button, and a way to keep your “usual items” handy.

You want: a simple way to track a daily habit.

Spanner can create: a tracker where you log each day in seconds, add a short note when needed, and review your past entries later.

You want: a checklist you can reuse every week.

Spanner can create: a reusable checklist (like “Laundry”, “Clean kitchen”, “Trash/recycling”) with optional reminders or notes depending on what you ask for.

What Spanner is (and isn’t)

Spanner is a way to get a personal app made for a specific task you want to make easier.
Spanner isn’t a one-size-fits-all template you have to force yourself to use.
