Hey PH. Solo dev here. This started because opening email attachments on Android was ridiculous. One app for PDFs, another for spreadsheets, a third for archives, and every one of them wanted a subscription, an account, or to send the file to a server to "convert" it. So I built one app that opens things. Then it grew into one that edits them too. PDFs: sign, fill forms, type, insert images, rearrange pages, merge, split, password-protect. Word and PowerPoint: text, formatting, tables, comments, footnotes, tracked changes. Excel: cells, formulas, sort, freeze panes, charts. Plus images, CSV, SQLite, Markdown, code, archives, fonts, certificates, and a text/hex view for anything unknown. The unusual part is under the hood. The Office and PDF engines are written from scratch to run entirely on-device, so the app ships with no INTERNET permission at all. Not "we promise we don't upload your files". Android's own App info screen shows "No permissions requested." No ads, no analytics, no accounts either. A side effect of writing everything from scratch: the whole app is about a 5 MB download. There are some limits, it's not desktop Office. Complex layouts render simplified, for example legacy .doc/.xls/.ppt open as extracted text only. I'm receiving feature requests daily and the app has much room to grow and improve. Free to open your first 30 files, $5 one time to unlock. Android only for now. I'll be around all day. Happy to answer any questions.

Handles everything I threw at it without needing to grant internet access, which is rare these days. The 5MB size and one-time $5 after the trial feels fair for something this practical.

 Appreciate it, glad it’s helpful. Let me know if there’s any file type you’d like it to handle better.

Handy little app that just works without begging for internet access, which is rare these days. Opened a stubborn .sqlite file I'd been meaning to peek at for weeks.

 thanks, similar to the last comment xD
