Four apps for everyday work — finding your nearest mosque, keeping a shop's credit book, reading a fabric's colour, naming a Quran recitation. And three desktop tools for the people who look after databases. Very different trades, one habit: the work happens on your own device, and nothing is quietly sent anywhere.

What's new · September 2026
Pick a product. Each step points at one thing that changed.
The ledger now gets settled too: payments, disputes and reminders.
A redesigned app, and a library 28 times the size.
Edits you review before they run, and data that moves between clusters.
Safer writes, code you can paste, and staging that matches production.
Edit values safely, see where memory goes, and diff two servers.
Apps for everyday work
Phone-first, free to the people using them, and built to keep working where the signal doesn't. Each has its own home under abdohoo.app, with its own site and its own support.
Find the mosque nearest you, and the times it prays.
Nearby masjids with their Adhan and Iqaamah timings, Jumuʼah, Ramadan schedules and announcements — kept current by the imams who run them. The Android app holds prayer times, reminders and a Qibla compass on the handset.
One credit ledger the shop and the customer can both read.
The shopkeeper writes the entry at the counter, even with no signal, and the customer opens the same ledger on their own phone — not a photo of a notebook page, and not a number they have to take on trust.
Photograph the cloth, read the colour, mix the dye.
Built for dyeing masters and textile units. Put a swatch and a sheet of white paper in frame, and Shadecard fuses three locked-exposure shots into one CIELAB reading, matches it against 13,297 shades, and hands back a yellow:red:blue ratio and a depth.
Hold up a phone to a recitation and know the surah, the ayah and the reciter.
A Quran recitation companion. It names what is being recited — a radio, a mosque speaker, a friend — and follows a Taraweeh imam or a student word by word, marking missed, wrong and added words and skipped ayahs as they happen, and prompting when the reciter is stuck.
Developer tools · devdesk.abdohoo.app
Windows, macOS and Linux. Connection credentials go to the OS keychain, the licence is checked offline, and no telemetry is collected or sent — because database tooling is routinely run on machines with no route to the internet, and on data that must not leave the building.
ScyllaDB · Apache Cassandra
A CQL workbench that lints before the server refuses, typed row forms for every CQL type, exact ring ownership from vnode tokens, and a keyspace ERD that draws the relationships a wide-column model actually has.
MongoDB 4.4+ · Atlas
Real JavaScript against a db handle with mongosh conventions honoured, documents flattened into typed columns by dotted path, field shape sampled with $sample, and an index advisor that reads $indexStats.
Redis · Valkey · KeyDB · Dragonfly
A SCAN-based key tree that never runs KEYS *, a dedicated editor for every core and module type, a linter that knows which commands hurt, keyspace analysis by namespace, and an advisor that hands you the command that fixes each finding.
The next address is already waiting. If you have something that needs to survive a patchy connection, a shared phone, a language most software skips over — or a database nobody has written a decent client for — we'd be glad to hear about it.
How we build
They hold whether the user is a shopkeeper with one bar of signal or an engineer on an air-gapped jump box.
Entries are written to the phone first and sent on when a connection returns. On the desktop, connection credentials go to the OS keychain, the licence is verified offline against a key compiled into the binary, and nothing is collected or sent. No product here needs our servers to be useful.
Not just the buttons. Credit Khata carries fourteen languages; in Shadecard even the refusal messages and the dyeing terms are written in Urdu. Each one is set in its own script, with right-to-left laid out properly rather than mirrored as an afterthought.
Shadecard refuses a recipe rather than guessing when the light is wrong. The database tools probe what a server supports and hide what it cannot do, warn before an expensive command, and show the exact statement before it runs. A tool you can trust is one that declines.
Salah Locator is free for everyone, with no ads at all. Customers reading their own ledger never pay. The desktop tools are commercial — and even there, a lapsed licence never locks you out of reading your own data during an incident.
