Once you are in: • Today, the session you are doing today, with pace targets and coach notes • Your Week, drag a session to another day when life gets in the way • Your Plan, every week from now to race day and the two weeks after • Progress, how consistent you have been and how training is feeling • Feedback, tell your coach how a session actually went in under a minute • Messages, ask your coach about niggles, nerves and everything else • Reminders that name the session, not just the time • Works offline on the trail and syncs when you are back APPLE WATCH, WIDGETS AND APPLE HEALTH (for runners with a plan) • Today's session on your wrist, plus the next few days coming up • Start the real structured workout: warm-up, intervals, cool-down • Live heart rate, distance and calories while you run • Home Screen and Lock Screen widgets for today, or for the whole week • Sessions scheduled into the Apple Workout app, so you just press start • Resting heart rate and sleep read from Apple Health to fill in your feedback • Send your plan to its own calendar on your phone Optional in-app purchase: Unlimited Saves, a one-off unlock that lifts the one-save-per-tool limit across all four free tools. Full Potential is made by Full Potential Performance Ltd, a UK coaching team who have spent over ten years looking after charity marathon runners, most of them standing on a start line for the very first time.

CREST
Read full descriptionHide full description
Most lifting apps are a notebook. CREST is a scoreboard: log only your new maxes, and see exactly how strong you are. NO ACCOUNT. NO ADS. NO WORKOUT LOG. Open it, log a PR, close it. Your lifts stay on your phone. YOUR LIFTS RANKED From Wood to Olympian, against lifters at your bodyweight. Your overall rank comes from Push, Pull and Legs, and every lift shows the kilos to its next rank. PRS THAT COUNT YOUR BODYWEIGHT A PR is measured as a share of your bodyweight on the day you lift it, so a lighter you lifting the same counts for more. KNOW WHEN TO GO FOR IT (PRO) CREST reads your reps, compares them to your real best, and says: ready for a PR, try 97.5 kg. One tap to log it. STRONGER SINCE DAY ONE One number for how much stronger you are since your first PR, with the climb as a chart. Per lift: your maxes for 1, 5 and 10 reps, your PR history, plates per side, and gym milestones like the 2-plate bench. COMING FROM ANOTHER APP? Import your history from its CSV export in one tap. SHARE IT Clean cards for a new PR, your rank and your progress, on your own photo if you want one. CREST PRO Free keeps one Push, one Pull and one Legs lift (one more for telling a friend), with your ranks, progress and share cards. Pro adds when to go for a PR, the weight to try, and every lift you train. $2.99 a month, or $17.99 a year with 7 days free. Payment is charged to your Apple ID. The subscription renews automatically unless cancelled at least 24 hours before the period ends; manage or cancel it in your App Store account settings.

Verdict
The clearest difference is device support: Full Potential Training at 3 against CREST's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.
