You used Ministry Assistant on Android and now you want WitnessWork on iPhone. This page merges both backups and builds a restore file.
Go to conversion
Your files never leave this device. Conversion runs in the browser — nothing is sent to the internet.
Open Ministry Assistant. In the menu, look for backup (not “export to text”).
Avoid “device storage”: Android hides that folder and you only get it with a cable. Also skip export to text — that .txt file does not include the real hours.
On your phone or computer, open Google Drive, find the backup, and download the .mabackup to an easy place (Downloads, for example).
You do not lose hours or records already in Witness Work. This page does a merge: it joins Ministry Assistant data with the current iPhone backup. Only days that were not already there are added.
Without the WitnessWork JSON, migration creates a generic publisher and skips your setup.
Pick both backups and tap the button. The page builds a new file to restore in WitnessWork — without erasing what you already had on iPhone, only adding the Android data.
Tap or drop the .mabackup
This is the file from step 1. The name looks like MABackup-… .mabackup
Tap or drop the backup JSON
This is the file from step 3. Without it, your iPhone profile is not kept.
When it finishes, the file goes to Downloads. The summary appears here.
How you restore depends on where you used this page:
If you did it on iPhone
In WitnessWork: menu → Backup and restore → Restore from a backup → choose the file this page downloaded (usually in Downloads).
If you did it on a computer
Send the generated file to yourself on WhatsApp. On iPhone: open the file in WhatsApp → Share → More → Save to Files → an easy folder (Downloads). Then restore that backup in WitnessWork as above.
Check a month you remember (field hours and LDC/Bethel). If something looks wrong, keep the old Drive backup and the WitnessWork JSON.
It reads the gzip/Smile Ministry Assistant backup, extracts hours (field and LDC/Bethel), contacts and visits, and builds JSON in the WitnessWork format. If you also upload the current iPhone backup, your profile and hours already logged are kept.

If you use Ministry Assistant on Android and prefer a different iPhone app (not WitnessWork), get in touch. Send a backup of the app you are using on iPhone. This is not a promise: if it is possible, we will try to build the conversion and publish it for free, like this one.
