App rescue & long-term maintenance

Your developer left. The app still has to work.

Anyone can generate an app now. Almost nobody will still be answering the phone about it in two years. If you're holding an app whose author is gone, the code is a mystery and Apple keeps sending emails — that's a job I take.

This is for you if

What you get

  • Code and infrastructure audit, in plain language, with the risks ranked
  • Recovering accounts, certificates, signing and store access
  • Stabilisation, then release back to the stores
  • Ongoing care plan: OS updates, store policy changes, crash monitoring, small changes
  • A written record of how everything works, so you're never in this position again

What I don't do

  • Rewrites sold as maintenance — if a rewrite is genuinely the answer, I'll say so and price it separately

If your project needs something on this list, I'll say so on the first call and point you to someone who does it.

Proof I can do this

I maintain my own products in both stores through every OS release and policy change. Maintenance isn't a service I bolted on — it's the part of the work I already do every month.

iOS · Android · Web Live

ProWord

Vocabulary learning across iOS, Android, web and backend — designed, built, shipped to both stores and maintained solo.

How we'd work together

01Free project review

Free · 2 working days

Send me what you want built. You get a price range, a timeline, a technical approach and an honest market check — including whether something off the shelf already does the job.

02Intro call

Free · 30 min

You describe what you have and what you need. I tell you straight whether I'm the right person, and roughly what it costs. No deck, no pitch.

03Blueprint

€1,200 · 1 week

A fixed-price week that removes the unknowns: technical approach, what talks to what, the risks worth worrying about, and a fixed quote for the build. Yours to keep, even if you hire someone else.

04Build

Fixed price, quoted after the review

Fixed scope, fixed price, in phases you can stop between. Code lives in your repository from day one. You see something working every week.

05Care plan

Monthly, agreed up front

The part most people skip. OS updates, store policy changes, certificate renewals, crash reports, small improvements — and one person who answers the phone when something breaks.

I won't be the cheapest quote you get. If cheapest is what you need, I'll say so on the first call rather than waste your time.

Priced in euro. I invoice as a registered sole proprietor (FOP) in Ukraine, so no VAT is added by me — an EU business client handles it as a normal non-EU supplier invoice.

Tell me what you're trying to do.

Send it over and I'll come back with a price, a plan and an honest market check — free, within two working days. Or book a call if you'd rather talk.
