Introducing TuTrail: the trail, exactly as you walked it

TuTrail records the trail, exactly as you walked it. It is a GPS track recorder for hiking, trail running, cycling and walking — it logs where you went, how much you climbed and how long you were actually moving, then it stays out of the way. No account, no ads, no analytics. Your tracks stay on your phone.

Recording

Four activities, each with its own pace and calorie model. Live distance, moving time, speed, altitude and elevation gain update as you move. Auto-pause stops the clock when you stop, and resumes when you set off again. Recording keeps running with the screen off or the app in the background — and if iOS closes it mid-hike, the unfinished recording is offered back on the next launch.

RFCReader Plus and RFCReader Pro: no difference in functionalities

Leave a reply

Short answer: they are the same app. Same features, same document formats, same search, same favourites, same dark mode. If you put RFCReader Plus and RFCReader Pro side by side on two devices, you could not tell them apart from the inside — the only visible difference is the corner of the icon.

The real difference is how you pay. RFCReader Pro costs $1.99 up front and everything is unlocked the moment you install it. RFCReader Plus is free to download and unlocks the same full feature set through a single in-app purchase. There is no subscription in either one, and no feature is exclusive to either app.

Introducing CodeInsight: a powerful source code reader

Leave a reply

CodeInsight is out now. It opens tar, tar.gz and zip archives without unpacking them, indexes every function and struct with ctags, and lets you jump through millions of lines of C — offline, on the device in your hand. The pitch is simple: a kernel source tree should read like it does in an editor, not like a folder of text files.

Open the archive. Don’t unpack it.

Point CodeInsight at a kernel tarball and start reading immediately. The app records file offsets once, then seeks straight to any file inside — so a 24 MB source tree becomes browsable in seconds, without a second expanded copy eating your storage.

Introducing RFC Reader: every RFC, in your pocket

Leave a reply

RFC Reader is out now. It is a reader for the entire IETF document series — every RFC from 0001 to the newest publication, in three formats, cached on your device so you can keep reading on a plane, in a basement meeting room, or anywhere else the network gives up.

Most of us meet an RFC as a browser tab: a 200-page text file, no table of contents, horizontal scrolling on a phone, and a search box that belongs to the browser rather than to the document. RFC Reader is built the other way round. Every screen exists for one thing — getting you through a long technical document without losing your place.

Welcome to @MeAI — support and news for our iOS apps

1 Reply

Welcome to @MeAI. This site went live on 21 October 2026, and it exists for a single reason: to support the iOS apps we build. It is not a company blog and not a place for announcements about ourselves — it is the place you come to when you want to know how one of our apps works, what changed in the latest version, or how to get help.

Everything here is written for people who already have the app on their device. Each post covers one product, explains a feature in enough detail to be useful, and points you at the next step — whether that is downloading, upgrading, or sending us a message.
