Four tools · Two desktop, two Android

Software that runs on your machine, not ours.

SuperDaveLab makes small, careful tools that do their work where your data already is. Statements, spreadsheets, cycle history, medication records — none of it is uploaded anywhere, because there's nowhere to upload it to. No accounts, no servers, no subscriptions.

Desktop tools · Windows, macOS and Linux

Getting data out of files and into shape

Two standalone desktop apps for the unglamorous part of working with financial and tabular data. Both read your files on your own computer and never send them anywhere.

LedgerSprout reviewing the rows extracted from a bank statement

LedgerSprout

Statement PDFs into clean spreadsheet data.

Import bank and credit card statements, review every extracted row before you trust it, and export files you can use straight away for bookkeeping and tax prep.

  • Review and correct transactions before export
  • Export to CSV and XLSX, with QFX and direct database export on Pro
  • Local OCR for scanned, image-only statements
  • Parsers for the major banks, and you can request your own
Recruiting beta testers Free tier

Free to try on your own statements $129 one-time · Pro $349/year

LedgerDock's preflight report naming what would break before an import runs

LedgerDock

Spreadsheets into a real database, without the mess.

Read a CSV or Excel file, fix up the table structure, check the whole thing against your actual database before anything is written, then export SQL or import directly.

  • Preflight tells you what will fail before the import, not after
  • SQL Server, PostgreSQL, MySQL and SQLite
  • Handles files far past what Excel will open
  • Saved recipes and a headless command line for scheduled runs
Recruiting beta testers Free tier

Free for review and SQL scripts $29 one-time for Pro

Android apps · Free and open source

Two apps that keep something private, privately

Both are free, MIT licensed, and built without permission to use the internet — Android itself stops them from sending anything anywhere. No ads, no premium tier, nothing to sell you.

Ebb

A period tracker that keeps your data on your phone.

Tracks your period, estimates the next one honestly — as a range, with how sure it is — and reminds you beforehand.

  • Reminders scheduled on the phone, so they work offline
  • Forgiving about missed logs and one-off odd cycles
  • Move to a new phone by scanning a few QR codes
Free · MIT Public beta
Ebb's home screen: day 10 of the cycle on a ring, with the next period expected between two dates

Nexpill

Medication reminders that arrive on time.

Written by a caregiver, for caregivers: when each dose was given, when the next one can be, and a reminder on the minute.

  • Exact alarms the phone keeps itself — no signal needed
  • Intervals, set times, as-needed, and tapers that change by date
  • A dose record you can export for the doctor
Free · MIT Public beta
Nexpill's home screen: one patient's medications, an overdue dose at the top and the next due in minutes

The same promise across all four

The question “what do they do with my data?” has a boring answer: nothing, because it never reaches us.

Nothing leaves your device

Statements are parsed on your computer; cycle and dose records live in a database on your phone. Files only go somewhere else if you move them yourself.

No account to make

There's no sign-up, no server holding your data, and nothing to lose access to. The desktop apps are licensed by a key on your machine, not a login.

Pay once, or nothing

The desktop tools have a free tier and a one-time price. The Android apps are free outright — no ads, no premium tier, no upsell.

Check our work

Ebb and Nexpill are open source under the MIT licence, and the releases are built from that same code. Read it on GitHub.

About

A small shop with a narrow habit

SuperDaveLab is a one-person software shop. Everything here came out of a job that needed doing — a pile of statements to get into a spreadsheet, a file that had to land in a database without breaking it, a cycle worth tracking without handing it to anyone, a medication schedule that couldn't slip in the middle of the night.

The habit they share is keeping the work local. It's the simplest answer to a question these tools all raise, and it means each app does its job with no signal, no account and no one else involved.

LedgerSprout and LedgerDock are how the free apps get paid for. Buying one keeps Ebb and Nexpill free for everybody.
