Hey r/apps — I'm a solo indie developer and I wanted to share an app I've been working on called TabulaDB. It's a personal database builder for iPhone.

What it does

TabulaDB lets you create custom databases to organize pretty much anything — home inventory, book collections, wine cellars, fitness logs, movie watchlists, contacts, vinyl records, you name it. You define your own fields (there are 15 types including text, dates, ratings, picklists, images, currency, color, and file attachments), then add records and view everything in a clean grid or detail view. It comes with 7 built-in templates to get you started, or you can build something completely from scratch.

It also has iCloud sync so your data stays in sync across devices, CSV export, full backup/restore (to a self-contained .tabulabackup file), and a reports section with charts that auto-generate based on your data.

Why it might be a better fit

There are a few personal database apps out there (Collections, MobiDB, Firevault, etc.) and they're solid. What I was going for with TabulaDB was something that's native Swift, modern (built with SwiftUI and SwiftData, iOS 18+), lightweight, and doesn't require you to wrestle with a spreadsheet or learn a query language. It's designed for regular people who want structured data without the overhead.

A few things that set it apart: the built-in templates are genuinely useful starting points (not just empty shells), the reporting/charts adapt to your data automatically, and the backup format is a single portable JSON file so your data is never locked in.

Cost

The app is free to download with a 7-day trial of all features. After that, TabulaDB Pro is a one-time purchase of $4.99 — no subscription, no recurring charges, you own it. The free tier still lets you create up to 2 databases with up to 100 records each, so you can kick the tires before deciding.

I'm the developer — happy to answer any questions or take feedback. This is genuinely a passion project and I'm building it because I wanted something like it for myself. If you try it out, I'd love to hear what you think.

Hey everyone, indie dev here. I built XVert because I was tired of unit converter apps that either nickel-and-dime you with subscriptions or only cover the basics. XVert is a one-time $1.99 purchase — pay once, own it forever, no recurring charges.

What it does:

It covers 22 conversion categories — the usual stuff like length, mass, and temperature, but also categories most converters skip: torque, data speed, electric charge, acceleration, force, resistance, and more. Within those categories I've included units you don't always see, like troy ounces, Mach speed, furlongs, BTU, RPM, and time units that go all the way from nanoseconds to millennia.

What makes it different — the Formula Builder:

This is the feature I'm most proud of. Beyond standard unit-to-unit conversion, XVert has a full expression-based formula builder. You define your own variables, then build a formula using those variables, constants, operators (+, −, ×, ÷), and parentheses. It evaluates live as you type in values.

It ships with a few built-in formulas to get you started (tip calculator, sales tax, hourly wage → annual salary, shoe size converter, dog years), but you can create whatever you need. I use it for stuff I look up way too often — splitting a bill, estimating fuel costs, quick pace calculations.

You can also export and share formulas as .xvformula files via AirDrop or the share sheet, and import ones other people have made.

Other details:

• Custom numpad with one-tap copy to clipboard and unit swap
• Adjustable decimal places (1–10)
• Grid or list view for categories
• Per-formula decimal place overrides
• No ads, no tracking, no account required

I'm a solo developer and this is one of three apps I've built and shipped. Happy to answer any questions or take feedback. Thanks for checking it out!
