Hanno Welsch · building apps since 2008

Apps that simply work.

I build apps for iPhone, iPad and Android – large type, clear colours, no ads and no tracking. And custom software for companies since 1989.

My apps

For everyday life, health and the dog

Each app does one thing properly. The data stays on the device, or is end-to-end encrypted when several people share it.

iDay

Never forget a birthday
New: version 8

Birthdays straight from your contacts, a reminder at the time you choose, star signs, horoscopes and the moon phase – plus a birthday card by email or WhatsApp. In the App Store since 2009, now completely rebuilt.

RamuKauf

A shared shopping list

One shopping list for the whole family. What one person writes down, everyone sees at once – on the phone, Apple Watch, Wear OS and Garmin watches.

RamuInfo

The family noticeboard

Appointments, notes, arrangements: all in one place, visible to everyone and end-to-end encrypted.

RamuPhone

Calling with large tiles

Ten large tiles with a picture and a name: tap, call. For everyone who finds the address book too fiddly.

RamuDates

No more forgotten dates

Birthdays, anniversaries, days to remember – whatever comes next stands large and clear on the screen.

BackPlaner

A timetable for baking bread

Several bakes in one day, each with its own sequence of dough, proving and oven: BackPlaner adds the times up for you.

Nidra Relax

Deep relaxation with Yoga Nidra

Guided Yoga Nidra sessions of various lengths that lead into deep relaxation – in German, English and Spanish.

RückenDoc

Active against back pain

Exercise programmes for the back. Apple picked the iPad edition RückenDocHD in its iTunes Rewind as one of the five best health apps for iPad.

iBodyPro

Fitness at a glance

Recommended by the ZDF WISO team: weight, measurements and progress in one place.

ichNehmAb!

Losing weight with an overview

Record your own weight history and let exactly that keep you going.

Dr.Watson

What is actually in there?

A reference work on food additives and ingredients – explained in plain words instead of E numbers.

Lunella

Season calendar for female dogs

Record the season, understand the phase and work out when the next one is due. Soundly based, and all data stays on the device.

YapYap

For dog owners

The app for life with a dog: walks, habits and everything else that goes with it.

ScalePractice

Guitar scales, practised properly

One key, one position, the matching fingering: 311 exercises for working through the fretboard systematically.

Services

Software that fits you

From the first idea to the app in the store – or bringing an application that has served you well for years up to date.

Apps for iOS and Android

Turnkey, native or with shared code in .NET MAUI – including store listing, subscriptions and maintenance.

Modernisation

Moving proven apps to current platforms without losing data or customers – as iDay went from Objective-C to .NET MAUI.

Software for companies

Custom programs for a range of industries, written to order for over 30 years – from the desktop to the server.

Web and backend

Interfaces, databases and web applications – including a secure backend for your app with end-to-end encryption.

About me

Hanno Welsch

I have worked as a freelance developer since 1989. Some of my apps appeared in 2008 when Apple's App Store opened – and are still maintained today.

What matters to me is software that works without detours: clear controls, honest prices, no advertising and no passing on of data. That holds for my own apps as much as for work done to order.
